The ABB PSTX370-600-70 Softstarter is engineered for medium to large three-phase motors, providing a rated maximum operational current of 370 A and an operating voltage range from 208...600 V AC. It features a three-phase control soft start and stop through a voltage or torque ramp, with built-in bypass for easy installation and energy saving. The PSTX offers functions such as current limit, kickstart, analog output, EOL, motor heating, and pump cleaning.The PSTX also includes features like jog, braking, stand-still brake, diagnostics, sequence start, and emergency/fire pump mode as standard. It comes with a detachable full graphic display with IP66 and 4x outdoor rating, allowing for four communication methods: hardwire inputs Start/Stop/Reset of fault, three programmable digital inputs, built-in Fieldbus communication Modbus RTU, and optional ANYBUS modules with various protocols such as Profinet, Profibus, Modbus TCP, Ethernet IP, and others. The PSTX is a versatile alternative for any motor starting application, suitable for medium to large three-phase motors with nominal currents from 30...1250 A inline connection or 52...2160 A inside delta connection.
