Product details

The ABB 1SFA898120R7000 is a PSTX1050 soft starter with auto phase sequence detection, designed to ramp three-phase induction motors up and down smoothly, reducing mechanical shock and inrush current. Rated for 208 to 600 V AC at 50/60 Hz, it carries a UL/CSA horsepower rating of 400 Hp at 200-208 V AC three-phase. Built-in electronic overload protection eliminates the need for a separate overload relay, saving panel space and wiring.

Ramp and protection depth

Ramp time is adjustable from 1 to 120 seconds, with initial voltage during start configurable from 10 to 99%. Protection functions include locked rotor, earth fault, phase reversal, under/over voltage, current imbalance, and PT-100 connection for motor thermal monitoring. Warning outputs cover current imbalance, underload, electronic overload time-to-trip, faulty fan, locked rotor, and THD(U) among others.

Supports Modbus-RTU, Modbus-TCP, Ethernet/IP, EtherCAT, DeviceNet, CANopen, Profibus, Profinet, BACnet-IP, and BACnet-MSTP — covers nearly every industrial network in a single unit. Analog outputs provide 0-10 V, 0-20 mA, or 4-20 mA signals for external monitoring or trending. Dedicated run, fault, bypass, and overload signal relays are built in, plus a 24 V DC control circuit and a separate 100-250 V AC control supply for the logic.

RoHS compliant per EU Directive 2011/65/EU and Amendment 2015/863, classified as Business To Business WEEE Category 4 (Large Equipment).
