Softstarter PSR3-600-11 / 1.5kW at 400V 1SFA896103R1100

Compact motor starter – PSR3-600-11

This softstarter from the PSR series by ABB is a compact and efficient method for limiting the inrush currents of three-phase motors. The device is designed to work with motors up to 1.5 kW at 400V, making it an ideal solution for both simple industrial applications and more demanding installations. Compact dimensions allow for mounting in tight spaces, and the built-in bypass contactor minimizes energy losses and simplifies connections.

Application and functionality

The PSR3-600-11 softstarter is a versatile device that finds application in a wide range of applications such as pumps, fans, conveyors or compressors. Its main function is smooth motor starting and stopping, which translates to reduced mechanical and electrical stress on the installation. Adjustable start-up parameters allow the device to be adapted to the specific requirements of a given application. This makes it possible to minimize inrush currents and extend the life of connected devices.

Construction and mounting

The device is characterized by a solid construction and ease of mounting – it can be mounted both on a DIN rail and directly on a mounting plate. The built-in bypass contactor ensures reliable operation of the device in continuous mode. PSR3-600-11 is designed to operate in ambient temperatures up to 40°C, and its IP20 protection class provides basic protection against touch and ingress of solid objects. The control voltage can be powered from both AC (24V) and DC (24V) networks, which increases installation flexibility. Additionally, the device has an adjustable tripping class, which allows for precise tuning of operating parameters to specific needs. Low power consumption (12 VA) minimizes energy losses during device operation.
