ABB 1SFA897104R7000 is the PSE37-600-70 PSE soft starter for low-voltage three-phase motors that need smooth acceleration, controlled stopping and reduced mechanical stress. This ABB PSE unit is selected for 37A rated operational current and a 18.5 kW 400 V motor class, making it a practical choice for pumps, fans, compressors, conveyors, HVAC equipment and industrial motor-control panels.

The ABB PSE37-600-70 softstarter combines two-phase control, voltage ramp and torque ramp functions with built-in bypass contacts, so panel builders can reduce heat losses and simplify wiring. ABB 1SFA897104R7000 operates on a 208...600 V AC main circuit and uses a wide 100...250 V AC, 50/60 Hz control supply. Core protection and commissioning functions include current limit, kickstart, electronic overload, underload detection, locked rotor protection, start/stop inputs, fault reset and clear LED display indication.

Use 1SFA897104R7000 / PSE37-600-70 when a compact ABB motor starter is required for medium-duty installations where direct-on-line starting would create high inrush current, belt shock, water hammer or unnecessary mechanical wear. The PSE family is also searched by buyers as ABB PSTE soft starter, but the official ABB reference for this part number is PSE37-600-70. It is suitable for maintenance replacement, new panel assembly, pump control panels and factory automation upgrades.
