Manual Motor Starter Function

The primary function of ABB 1SAM250000R1013 is to provide local manual switching and protection for an electric motor circuit. The operator can use the rotary handle to switch the motor circuit between its operating states, while the integrated protective mechanism responds to specified fault conditions.

Unlike a simple manual switch, the MS116-20 incorporates thermal and magnetic protection functions. This allows the device to respond to motor overload and short-circuit conditions while also providing a manual means of controlling the motor circuit. ABB describes the device as a manual motor starter, motor protection circuit breaker, or manual motor protector. :contentReference[oaicite:3]{index=3}

The combination of switching and protection makes the MS116-20 suitable for control panels where a motor requires a dedicated protective device without relying on a separate fuse for the primary short-circuit and overload protection functions.

16–20 A Adjustable Current Setting

ABB 1SAM250000R1013 has an adjustable current setting range from 16 A to 20 A. The adjustment allows the motor protection setting to be matched to the applicable motor circuit within the specified range. The rated operational current of the MS116-20 is 20 A. :contentReference[oaicite:4]{index=4}

The adjustment should be selected according to the motor nameplate data, applicable electrical regulations, installation conditions, and the requirements of the complete protection system. The setting should not simply be selected according to the maximum value of the device.

Correct current adjustment is particularly important for motor protection because the motor’s normal operating current and starting characteristics must be considered when establishing the appropriate protective setting.

Short-Circuit Protection

The MS116-20 incorporates magnetic protection for short-circuit conditions. ABB specifies a rated service short-circuit breaking capacity of 10 kA at 400 VAC for this product. :contentReference[oaicite:5]{index=5}

The short-circuit protection function is intended to interrupt excessive fault current and protect the motor circuit and associated conductors from the effects of a short circuit. The actual protective coordination of an installation depends on the upstream supply system, prospective fault current, wiring, and applicable electrical standards.

A complete motor protection design should therefore consider the MS116-20 together with the upstream protective equipment and the characteristics of the connected motor.

Overload Protection

Motor overload protection is another important function of ABB 1SAM250000R1013. Motor overload can occur when a motor operates above its intended load for an extended period, causing increased current and thermal stress.

The MS116-20 uses a thermal protection mechanism to respond to overload conditions. Its trip behavior is associated with trip class 10A, providing a defined operating characteristic for motor protection applications. :contentReference[oaicite:6]{index=6}

The adjustable 16–20 A range allows the protection setting to be selected according to the applicable motor operating current. This provides a more appropriate protection arrangement than using one fixed current value for every motor application.

Phase-Failure Protection

ABB specifies phase-failure protection among the protective functions of the MS116-20. Phase failure can create an abnormal operating condition in three-phase motors and may lead to increased current in the remaining phases and additional thermal stress.

The integrated protection system helps detect the relevant abnormal electrical condition and initiate tripping when the specified protective criteria are reached. The exact response remains dependent on the electrical operating conditions and the device’s protection characteristics.

Trip Class 10A

The ABB MS116-20 is specified with trip class 10A. Trip class provides information about the operating characteristic of the overload protection mechanism and is particularly relevant to motor applications.

The 10A classification allows the MS116-20 to be applied to suitable motors where the starting and operating characteristics correspond to the protective requirements. Motor starting current can be considerably higher than normal running current, so the protection device must allow appropriate starting behavior while still responding to sustained overload conditions.

The selection of a motor starter should therefore be based on the complete motor data rather than the current range alone.

Manual Switching and Rotary Handle

The MS116-20 uses a rotary handle for manual operation. ABB describes the handle as providing a clear indication of the switch position. :contentReference[oaicite:7]{index=7}

This arrangement gives the operator a direct visual indication of the device’s operating state. The manual switching function can be used when starting or stopping the connected motor circuit and during appropriate isolation procedures.

The handle design also forms part of the device’s disconnect function. The exact isolation procedure should always follow the electrical installation requirements and applicable safety procedures.

Disconnect Function

ABB specifies a built-in disconnect function for the MS116-20. This function allows the motor circuit to be manually switched off through the device’s operating mechanism. :contentReference[oaicite:8]{index=8}

The disconnect capability is useful in industrial control panels because motor circuits often require a dedicated means of switching the circuit off during equipment operation, maintenance, or system isolation.

The device should nevertheless be applied according to the applicable electrical safety requirements, and the presence of a disconnect function should not be interpreted as eliminating the need for a complete system-level isolation procedure.

Temperature Compensation

ABB lists temperature compensation as one of the features of the MS116-20. Temperature can influence thermal protection behavior, making compensation an important characteristic for motor protection equipment. :contentReference[oaicite:9]{index=9}

The compensation feature helps the protective characteristics remain appropriate across the device’s specified operating conditions. This contributes to consistent operation when the surrounding control-panel temperature changes.

The applicable ambient temperature limits should still be observed when designing and installing the motor protection circuit.

Trip-Free Mechanism

The MS116-20 incorporates a trip-free mechanism. This means the protective mechanism is designed so that the device can trip when a fault condition requires protection even if the manual operating mechanism is being held in an operating position.

This is an important characteristic for protective switching equipment because a protection device must be able to interrupt the circuit when its protective function determines that tripping is necessary.

Motor Application

ABB 1SAM250000R1013 can be applied to suitable single-phase and three-phase motor circuits. ABB documentation specifically states that the manual motor starter is suitable for both three-phase and single-phase applications. :contentReference[oaicite:10]{index=10}

In a typical industrial installation, the MS116-20 is placed in the motor feeder circuit. The device provides a local switching function and protects the connected motor circuit against the specified electrical fault conditions.

The correct configuration depends on motor current, supply characteristics, wiring, starting conditions, and the requirements of the complete motor control system.

Mounting and Compact Design

The MS116-20 uses a compact 45 mm wide housing. Its compact form factor is useful for industrial control cabinets where multiple motor protection devices must be installed within a limited panel area. :contentReference[oaicite:11]{index=11}

Product information also identifies DIN rail mounting for the 1SAM250000R1013 version. :contentReference[oaicite:12]{index=12}

The mounting arrangement allows the manual motor starter to be incorporated into conventional control-panel layouts together with contactors, terminal blocks, control relays, power distribution components, and other motor control equipment.

Accessory Compatibility

The MS116 series supports a range of accessories that can extend the functionality of the basic manual motor starter. ABB documentation identifies auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, three-phase busbars, power in-feed blocks, and locking devices among the available accessory options. :contentReference[oaicite:13]{index=13}

Auxiliary contacts can provide additional electrical status signals to a control circuit. Signaling contacts can provide information about a particular switching or trip condition. Undervoltage releases and shunt trips can support additional control functions where required by the application.

Busbar and power in-feed accessories can simplify the arrangement of multiple motor protection devices in a control panel, while locking accessories can restrict unauthorized operation where required.

Industrial Control Applications

ABB 1SAM250000R1013 is suited to industrial motor control systems in which individual motors require manual switching and integrated protection. Applications can include pumps, fans, compressors, conveyors, machine tools, material-handling equipment, and other electrically driven industrial machinery.

The MS116-20 can form part of a motor starter arrangement together with a contactor and associated control components. In such an arrangement, the manual motor starter provides motor circuit protection while the contactor provides electrically controlled switching.

The final motor-control architecture depends on the application, motor characteristics, control requirements, and applicable standards.

Electrical Installation Considerations

The installation of ABB 1SAM250000R1013 should be based on the electrical characteristics of the connected motor and the complete protection system. The current adjustment must be appropriate for the motor, while the short-circuit protection must be coordinated with the available fault current and upstream protection.

The conductors, terminals, mounting arrangement, and surrounding equipment must also be suitable for the electrical conditions of the installation. Product information identifies screw terminals and DIN rail mounting for this version. :contentReference[oaicite:15]{index=15}

The applicable ABB installation instructions and electrical standards should be followed for wiring, adjustment, commissioning, and maintenance.

Maintenance and Service

Maintenance of the MS116-20 should include inspection of the rotary operating mechanism, terminal connections, mounting position, and surrounding motor-control equipment. Loose connections, abnormal heating, mechanical damage, or unusual operating behavior should be investigated.

The current setting should also be checked against the motor’s required protection setting after maintenance or system modification. Accessories connected to the device should be inspected according to their respective technical requirements.

Because the device is part of an electrical motor circuit, maintenance should only be performed under appropriate electrical safety procedures.
