PSTX570-600-70 Softstarter by ABB
The softstarter PSTX570-600-70 has a rated maximum operational current of 570 A with an operating voltage span from 208 to 600 V AC. The rated control voltage is between 100 to 250 V AC at 50/60 Hz. It features a three-phase control soft start and stop through a voltage or torque ramp and built-in bypass for easy installation and energy saving. Relay outputs provide RUN, TOR, and Event signals in normally open state.
Functions include current limit, kickstart, analog output, end of line (EOL), motor heating, pump cleaning, jog, braking, stand-still brake, diagnostics, sequence start, and emergency/fire pump mode as standard. The device includes a detachable full graphic display with IP66 and 4x outdoor rating.
Communication options: hardwire inputs Start/Stop/Reset, three programmable digital inputs, built-in Fieldbus communication Modbus RTU, optional ANYBUS modules supporting protocols such as Profinet, Profibus, Modbus TCP, Ethernet IP, and others, and external adaptor with Fieldbus plug.
Suitable for medium to large-sized three-phase motors with nominal currents from 30 to 1250 A inline connection or 52 to 2160 A inside delta connection. Typical applications: pumps, fans, compressors, conveyors.
