Overview of ABB 1SBL137501R1300

The ABB 1SBL137501R1300 is an AF09-22-00-13 four-pole contactor. It belongs to the AF series of industrial contactors developed for reliable switching and control of electrical circuits. The device is configured with two normally open and two normally closed main contacts, providing a 2NO + 2NC contact arrangement.

The contactor is designed for power circuits up to 690 V AC under the applicable IEC ratings and can control motors with an AC-3 rating of up to 4 kW at 400 V. Its AC-1 rated operational current is 25 A at 690 V under the specified conditions.

The AF09-22-00-13 uses an electronic coil interface rather than a conventional single-voltage coil. Its 100–250 V AC/DC control range allows the contactor to accommodate substantial variations in the control supply while maintaining the same contactor configuration.

Product Identification

AF09-22-00-13 Contact Arrangement

The 1SBL137501R1300 has four main poles with a 2NO + 2NC arrangement. The two normally open contacts close when the contactor coil is energized, while the two normally closed contacts open. This configuration makes the contactor suitable for power switching applications where both normally open and normally closed circuits are required.

The main contacts form part of the power switching circuit. Additional auxiliary contact blocks can also be added to compatible AF contactors when extra electrical control or indication functions are required.

The contact arrangement should be considered when replacing an existing contactor. A visually similar four-pole contactor with a different contact configuration may not provide the same circuit functionality.

Wide Control Voltage Range

One of the important characteristics of the AF09-22-00-13 is its electronic coil interface. The control circuit accepts 100–250 V AC at 50/60 Hz as well as 100–250 V DC. This wide range reduces the need to select a separate coil for every individual control voltage within the supported range.

The electronic coil interface also allows the AF contactor to manage significant variations in the control supply. This is useful in industrial control panels where the control voltage may not remain at a single nominal value under all operating conditions.

Built-in surge protection is part of the AF contactor design. Consequently, the coil interface incorporates protection against the voltage transients associated with contactor operation, reducing the need for a separate external surge suppressor in applications where the integrated protection is appropriate.

AC-1 and AC-3 Ratings

The ABB 1SBL137501R1300 has an AC-1 rated operational current of 25 A at 690 V under the specified IEC conditions. AC-1 represents utilization categories involving non-inductive or slightly inductive loads, such as resistance loads.

For motor control applications under AC-3 conditions, the contactor is rated at 9 A at 380/400/415 V and can control motors with a rated operational power of 4 kW at these voltage levels. The AC-3 rating should be used when evaluating the contactor for motor starting and stopping applications.

The difference between AC-1 and AC-3 ratings is important when selecting a contactor. The appropriate rating depends on the load type, operating voltage, switching frequency, and application conditions.

Industrial Applications

The AF09-22-00-13 can be used in industrial electrical control systems where four-pole switching is required. Typical applications include motor control panels, heating equipment, pumps, ventilation systems, machinery, and general power switching circuits.

For motor applications, the contactor can be incorporated into a motor starter or control circuit together with suitable overload protection and other control components. The four-pole configuration can also be useful in applications where additional switching of conductors is required.

The contactor can also be used for non-inductive or slightly inductive loads within its applicable AC-1 rating. The actual application must always be evaluated according to the electrical characteristics of the connected load.

Electrical Characteristics

The main circuit of the AF09-22-00-13 is rated for applications up to 690 V AC under IEC requirements. Its conventional free-air thermal current is 35 A at the specified 40 °C reference condition, while the AC-1 operational current is 25 A at 690 V.

At 220/230/240 V, 380/400 V, and 415 V, the AC-3 operational current is 9 A. At 500 V, the AC-3 current increases to 9.5 A, while the rating at 690 V is 7 A. These values demonstrate why the exact operating voltage must be considered when selecting the contactor.

The main circuit operates at 50/60 Hz, while the electronic control interface supports the specified AC and DC control voltage range. Screw terminals are used for electrical connections.

Mechanical Design

The ABB AF09 contactor uses a compact block-type design. The 1SBL137501R1300 has a product width of approximately 45 mm, a height of approximately 86 mm, and a depth of approximately 77 mm. Its compact dimensions allow it to be integrated into industrial control panels where panel space is an important consideration.

The contactor can accept compatible add-on accessories, including auxiliary contact blocks. These accessories allow the basic switching device to be adapted for control, monitoring, and signaling requirements.

When mounting the contactor, adequate clearance and suitable wiring space should be maintained. Installation should follow the applicable ABB instructions and the requirements of the electrical panel design.

Installation Considerations

Before installing the AF09-22-00-13, the control voltage and main circuit voltage should be verified against the requirements of the application. The wide 100–250 V AC/DC coil range does not mean that all control circuits should be connected without checking the actual supply voltage and wiring arrangement.

The main contacts should be selected according to the actual load category. For motors, the AC-3 rating should be considered rather than using the higher AC-1 rating as the primary selection criterion.

Wiring should be completed using suitable conductors and terminal tightening procedures. The contactor should be installed in an enclosure or panel that provides the environmental conditions required for the application.

Maintenance and Troubleshooting

Routine inspection of a contactor should include the main terminals, control terminals, mechanical operation, and surrounding wiring. Loose connections, excessive contamination, abnormal noise, or unusual contact behavior can indicate that further inspection is required.

If the contactor does not operate when the control signal is applied, the control supply should first be checked. Because the AF09-22-00-13 accepts a wide control voltage range, the actual supply should still be verified to ensure that it falls within the specified 100–250 V AC/DC range.

If the coil operates but the load circuit does not switch correctly, the main contact circuit and connected load should be inspected. In motor applications, overload protection and other components in the starter circuit should also be checked.

Replacement and Model Identification

When replacing an ABB AF09 contactor, the complete product identification should be compared rather than selecting a replacement based only on the AF09 family name. The 1SBL137501R1300 specifically identifies the AF09-22-00-13 configuration with four poles, 2NO + 2NC main contacts, and a 100–250 V AC/DC control interface.

Other AF09 models can have different contact arrangements and different coil voltage ranges. For example, AF09 variants with 24–60 V control circuits or other voltage configurations use different ABB ordering numbers.

Therefore, the ordering number, extended product type, pole configuration, control voltage, and electrical ratings should all be checked before integrating a replacement into an existing control panel.
