ABB PSR25-600-11 Soft Starter, 25A, 11kW, 208-600V AC, 24V AC/DC

The ABB PSR25-600-11 is a compact and efficient 3-phase soft starter engineered for precise motor control in industrial environments. Designed to handle a maximum operational current of 25 A and a power rating of 11 kW, this device operates seamlessly within a voltage range of 208-600V AC. It utilizes a 24V AC/DC control supply and features a robust, space-saving design that integrates easily into existing electrical cabinets.

Advantages

This soft starter provides a reliable solution for reducing mechanical stress and electrical surges during motor startup, which significantly contributes to extending the operational lifespan of connected equipment. The inclusion of a built-in bypass ensures energy efficiency during steady-state operation, while the two-phase control mechanism allows for smooth voltage ramping. Users benefit from straightforward configuration via front-mounted potentiometers, enabling quick adjustments to start and stop times. Furthermore, the device supports flexible integration options, including compatibility with manual motor starters and external fieldbus communication adapters.

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. Mount the unit on a standard DIN rail or surface within an enclosure that provides adequate ventilation. Connect the power supply and motor leads to the designated terminals. Use the three potentiometers located on the front panel to set the desired start and stop ramp times according to the specific requirements of your motor load. Ensure that the control voltage is correctly wired to the input terminals. Once configured, the device will automatically manage the motor startup sequence based on the defined parameters.

What to consider before purchase

• Ensure the motor current rating does not exceed 25 A.
• Verify that the 24V AC/DC control supply is available in your control circuit.
• Check the available space in your electrical cabinet against the unit dimensions.
• Determine if additional accessories like fieldbus adapters or mechanical connection kits are required for your specific setup.

Usage recommendations

For optimal performance and longevity, ensure the soft starter is installed in an environment free from excessive dust and moisture. Regularly inspect the electrical connections to ensure they remain tight and free from oxidation.
