ABB PSR12-600-11 Soft Starter 12A 208-600V AC 24V AC/DC

The ABB PSR12-600-11 is a compact 3-phase soft starter engineered for precise and efficient motor control in industrial environments. Designed to manage motors with a rated operational current of 12A, this device operates within a voltage range of 208-600V AC. By utilizing a voltage ramp for both starting and stopping, it effectively minimizes mechanical stress on equipment and reduces electrical surges during power-up. The unit features a built-in bypass, which simplifies the installation process while contributing to overall energy efficiency during operation.

Advantages

This soft starter offers a highly space-efficient design, making it an ideal choice for control panels where mounting area is limited. The inclusion of a relay output for the RUN signal allows for easy integration into existing monitoring systems. Users can quickly configure the start and stop ramps, as well as the ramp times, using the three intuitive potentiometers located on the front panel. Furthermore, the device supports high-frequency operation, capable of managing up to 100 starts per hour, ensuring reliability in demanding applications.

Suitable for

• Pumps and pumping systems
• Industrial fans and ventilation units
• Compressors
• Conveyor belt systems

This device may not be suitable for applications requiring complex motor control features, such as torque control or advanced diagnostic feedback, as it is designed for basic soft start and stop functionality. It is also not intended for use in environments where a higher ingress protection rating than IP20 is required without additional protective enclosures.

Key specifications

• Rated operational current: 12A
• Operational voltage range: 208-600V AC
• Control supply voltage: 24V AC/DC
• Protection rating: IP20
• Dimensions: 114 x 45 x 140 mm
• Weight: 400 g
• Control method: Two-phase voltage ramp

Installation of the ABB PSR12-600-11 is straightforward due to its compact footprint and integrated bypass functionality. The device is designed to be mounted within a control cabinet. Once mounted, the start and stop parameters are adjusted via the front-mounted potentiometers to match the specific requirements of the motor load. It is frequently paired with a manual motor starter to provide a complete motor protection and control solution.

What to consider before purchase

• Ensure the motor's nominal current falls within the 3-105A range supported by the PSR series.
• Verify that the 24V AC/DC control supply is available in your control circuit.
• Check if additional Fieldbus communication adaptors are required for your specific automation setup.
• Confirm that the IP20 rating is sufficient for your installation environment.

For optimal performance and longevity, it is recommended to ensure proper ventilation within the control cabinet and to verify that the start/stop ramp settings are calibrated according to the specific inertia of the connected load.
