PSR105-600-70 Softstarter, 105A, 208–600V AC

Description for PSR105-600-70 Softstarter, 105A, 208–600V AC

The PSR105-600-70 is a compact and reliable softstarter designed for smooth starting and stopping of small three-phase motors. With a maximum operational current of 105 A and an operating voltage range of 208 to 600 V AC, this device is perfectly suited for basic motor control applications.

Featuring a two-phase control system, the PSR softstarter manages motor ramp-up and ramp-down through voltage control, minimizing mechanical and electrical stress. The integrated bypass contactor enhances energy efficiency and simplifies installation.

Users can easily configure the start/stop ramp times using three potentiometers conveniently located on the front panel. The softstarter also provides relay outputs with RUN and TOR signals in normally open (NO) state, useful for monitoring and control purposes.

For integration flexibility, the PSR supports Fieldbus communication via an optional external adaptor and Fieldbus plug. It is commonly paired with ABB’s manual motor starters (MMS), with mechanical connection kits available for seamless assembly.

Ideal for small motors rated from 3 to 105 A and capable of handling up to 100 starts per hour, the PSR105-600-70 is widely used in applications such as pumps, fans, compressors, and conveyors
