ABB PSTX60-600-70 Soft Starter Controller Module

ABB PSTX60-600-70 Softstarter is a three‑phase motor soft starter designed for mains up to 600 V and a control supply of 100–250 V AC (50/60 Hz). It enables smooth start and stop of industrial motors via voltage or torque ramp, reducing electrical peaks and mechanical stress. The unit has a nominal inline current of 60 A with a current range of 18–60 A, supports mains in the 208–600 V AC range, and uses cable‑clamp terminals with an IP00 enclosure. Weighing about 5.6 kg, it includes an internal bypass for efficient operation once the motor reaches speed. Power ratings at 400 V are specified as 30 kW in-line and 55 kW (105 A) in delta configuration. Part number 1SFA898106R7000 places it in ABB’s PSTX60 family, which provides soft‑start and soft‑stop for three‑phase motors. Typical applications include conveyors, pumps, fans, and other equipment where controlled acceleration and reduced electrical stress are priorities. This ABB softstarter combines reliable ABB electronics in a compact form factor for panel installations and continuous-duty operation.
