HK1-11 Auxiliary Contact Function

The primary function of ABB 1SAM201902R1001 is to provide an auxiliary electrical interface for a compatible manual motor starter. The auxiliary contacts operate together with the main switching mechanism of the motor starter. When the main device changes its operating state, the auxiliary contact changes its corresponding electrical state.

This arrangement allows an external control system to receive information about the operating condition of the motor starter. Instead of monitoring the main power circuit directly, a control circuit can use the auxiliary contact to obtain a discrete electrical indication.

The HK1-11 therefore adds an additional signaling function without changing the fundamental motor-protection function of the MS116, MS132 or MS165 manual motor starter.

Normally Open and Normally Closed Contacts

The HK1-11 contains one normally open contact and one normally closed contact. This 1NO + 1NC arrangement provides two complementary switching states that can be incorporated into different control circuits.

A normally open contact is open in its defined normal state and closes when the auxiliary mechanism reaches the corresponding operating position. A normally closed contact operates in the opposite manner, providing a closed circuit in its normal state and opening when the switching mechanism changes position.

Having both contact types in the same accessory provides flexibility for status indication, control logic and interlocking circuits.

Mechanical Relationship with the Main Starter

ABB specifies that HK1 auxiliary contacts change position together with the main contacts of the manual motor starter. This mechanical relationship means the auxiliary contact provides an electrical representation of the main device’s switching state. :contentReference[oaicite:4]{index=4}

The accessory does not operate as an independent control switch. Its mechanical state is linked to the associated manual motor starter. Consequently, correct installation and mechanical engagement with the main device are essential for reliable auxiliary signaling.

When the manual motor starter is operated, the auxiliary mechanism follows the corresponding movement and changes the NO and NC contact states.

Side-Mounted Design

ABB 1SAM201902R1001 is designed for lateral installation. Product specifications identify the mounting type as side mounting, and ABB documentation describes HK1 auxiliary contacts as being installed on the right side of compatible manual motor starters. :contentReference[oaicite:5]{index=5}

The side-mounted architecture allows the auxiliary contact to be added to the motor starter without occupying the primary front operating area. This is particularly useful in compact motor-control assemblies where the main manual starter and its operating handle remain accessible while additional signaling is required.

The mounting arrangement must correspond to the compatible manual motor starter family and the installation instructions for the accessory.

Compatibility with MS116

ABB identifies HK1-11 as an accessory for MS116 manual motor starters. The MS116 family is used for motor switching and protection, while the HK1-11 provides additional auxiliary signaling capability. Product data specifically lists MS116 among the related devices. :contentReference[oaicite:6]{index=6}

When installed with an MS116 manual motor starter, the auxiliary contact follows the operating state of the starter and makes the corresponding NO and NC signals available to the external circuit.

The complete motor-control assembly can therefore combine the main motor protection function of the MS116 with auxiliary status information provided by the HK1-11.

Compatibility with MS132 and MS165

ABB product information also identifies MS132 and MS165 as compatible manual motor starter families for HK1 auxiliary contacts. ABB’s product description states that HK1 contacts are mounted laterally on the right side of MS116, MS132 or MS165 manual motor starters. :contentReference[oaicite:7]{index=7}

This compatibility allows the same accessory family to be used across several ABB manual motor starter platforms. However, the exact accessory selection should always be checked against the specific starter model and its configuration.

Compatibility should not be determined from physical dimensions alone. The mechanical interface and electrical requirements should correspond to the specified ABB product family.

Electrical Connection

ABB 1SAM201902R1001 uses screw terminals for its electrical connections. The terminal arrangement provides a direct connection between the auxiliary contact and the external control or indication circuit. :contentReference[oaicite:8]{index=8}

The normally open and normally closed contacts can be connected according to the requirements of the control circuit. One contact can be used for a status signal while the other can be incorporated into an interlock or another discrete control function.

The actual terminal numbering and wiring arrangement should be verified against the applicable ABB technical documentation before installation.

Auxiliary Signaling in Motor Control

Auxiliary contacts are widely used in motor-control systems because the main power circuit and the control circuit often require different electrical interfaces. The main contacts of a manual motor starter handle the motor circuit, while an auxiliary contact can communicate the device state to a lower-power control circuit.

For example, the HK1-11 can be incorporated into a control panel where a controller, relay, indicator or interlocking circuit needs to know whether the associated motor protection device is in its corresponding operating state.

This separation between power switching and auxiliary signaling simplifies the integration of manual motor starters into larger automation systems.

Control and Interlocking Applications

The 1NO + 1NC contact arrangement allows ABB 1SAM201902R1001 to support different control functions. A normally open contact can be used to provide a discrete signal when the manual motor starter reaches the corresponding position, while the normally closed contact can provide an inverse state.

This can be useful for electrical interlocking. A control system may use the auxiliary state to permit or inhibit another operation depending on the condition of the associated motor protection device.

The exact logic should be designed according to the electrical schematic and the safety requirements of the machine or process.

Motor Protection System Architecture

The HK1-11 should be understood as an accessory rather than as the primary motor protection device. The associated MS116, MS132 or MS165 manual motor starter provides the main switching and motor protection functions, while the auxiliary contact extends the available electrical interface.

This modular approach allows the motor protection circuit to be adapted to different control requirements. Where only motor protection is required, the main manual starter can be used in its basic configuration. Where status monitoring or additional control logic is needed, an auxiliary contact can be added.

The resulting arrangement is suitable for industrial control cabinets containing multiple motor circuits and automation devices.

Technical Specifications

The listed product characteristics correspond with ABB catalog information and supporting technical product data for HK1-11. :contentReference[oaicite:9]{index=9}

Switching Characteristics

Available product data identifies switching characteristics for the auxiliary contacts according to utilization categories. One technical listing specifies AC-15 values of 6 A at 24 V, 4 A at 230 V and 3 A at 400 V, together with DC-13 values for the listed voltage conditions. :contentReference[oaicite:10]{index=10}

These ratings describe the auxiliary contact circuit rather than the motor’s main power circuit. The auxiliary contact must therefore be selected and wired according to the electrical load connected to the auxiliary terminals.

The control circuit voltage and current should remain within the specified limits for the applicable utilization category.

Installation Considerations

Installation of ABB 1SAM201902R1001 begins with confirming that the associated manual motor starter is a compatible MS116, MS132 or MS165 model. The auxiliary contact is designed for right-side mounting, so its mechanical interface must align correctly with the main starter. :contentReference[oaicite:11]{index=11}

After mechanical installation, the auxiliary wiring should be connected to the appropriate screw terminals. The NO and NC functions should be identified according to the product marking and electrical documentation.

The auxiliary contact should engage properly with the operating mechanism of the main starter. If the mechanical connection is incorrect, the electrical state indicated by the auxiliary contacts may not correspond to the actual state of the main device.

Maintenance Considerations

Maintenance of the HK1-11 should include inspection of the mechanical mounting, terminal connections, contact wiring and interaction with the main motor starter. Loose terminals or incorrect wiring can affect the auxiliary signal even when the main motor protection device operates correctly.

The auxiliary contact mechanism should also be checked for proper movement with the associated manual motor starter. Any abnormal mechanical resistance or inconsistent contact behavior should be investigated according to the applicable maintenance procedure.

Because the accessory is part of an electrical control system, inspection and maintenance should follow the safety procedures applicable to the complete motor-control panel.

Applications in Industrial Automation

ABB 1SAM201902R1001 can be incorporated into motor-control circuits where the operating state of an MS116, MS132 or MS165 manual motor starter needs to be communicated to another part of the control system.

• Motor starter status indication
• Industrial motor control panels
• Electrical interlocking circuits
• Machine control systems
• Motor protection monitoring
• Control relay interfaces
• Industrial automation cabinets
• Auxiliary status signaling

The exact application depends on the electrical design of the machine or control panel. The auxiliary contact should be treated as a signal interface associated with the main manual motor starter.

Related ABB Accessories

ABB’s accessory catalog lists several related HK and SK auxiliary and signaling contact types. For example, 1SAM201902R1002 corresponds to HK1-20, while 1SAM201902R1003 corresponds to HK1-02. The ABB catalog also identifies 1SAM201901R1001 as HKF1-11, showing the broader range of auxiliary contact configurations available for manual motor starters. :contentReference[oaicite:12]{index=12}

These different product references should not be treated as interchangeable without confirming the contact arrangement and mechanical compatibility. The specific ABB article number 1SAM201902R1001 identifies the HK1-11 configuration.

Product Identification for Technical Records

For inventory and maintenance records, the recommended identification is ABB 1SAM201902R1001, HK1-11 Auxiliary Contact. The EAN code 4013614320361 can provide an additional identification reference where barcode-based inventory systems are used. :contentReference[oaicite:13]{index=13}

Recording both the article number and product type helps distinguish the component from similar ABB accessories. The associated manual motor starter model should also be recorded when documenting an installed assembly.

This approach is particularly useful in industrial automation environments containing multiple MS116, MS132 or MS165 motor protection devices.
