ABB PSTX142-690-70

The ABB PSTX142-690-70 softstarter is a solid choice for managing motors with a maximum operational current of 142 A and an operating voltage range between 208 and 690 V AC. Designed to handle three-phase control, it smoothly starts and stops motors using either a voltage or torque ramp, helping to prevent mechanical stress and reduce wear. With a rated control voltage from 100 to 250 V AC at 50/60 Hz, this softstarter also includes a handy built-in bypass, making installation straightforward while improving energy efficiency.

You’ll find useful relay outputs providing RUN, TOR, and event signals in a normally open (NO) configuration, which keeps integration simple. The unit comes packed with features like current limiting, kickstart for extra torque on startup, analog output, end-of-line (EOL) detection, motor heating protection, and pump cleaning functions. For added control, it also supports jog mode, braking, stand-still brake, diagnostics, sequence start, and even emergency or fire pump modes as standard.

If you’re looking to keep your motors running smooth without any hiccups, the PSTX142-690-70 is definitely a solid pick for the job. This product, also referenced as 320500501457, is available through BSP Automation, who provide reliable access to ABB’s industrial automation gear.
