If you're wiring it inside-delta, it carries 300 A / 160 kW at 400 V, which is the configuration for larger motors where the starter sees phase current instead of line current. The built-in electronic overload protection eliminates the need for a separate overload relay on the BOM — one device handles starting and protection. Ramp time is adjustable from 0 to 120 seconds, and the initial voltage during start sits between 30 and 70 % with a step-down special ramp from 100 to 30 %. That range covers soft starting for high-inertia loads like conveyors or fans, and soft stopping for pumps to avoid pressure surges. Control supply voltage is 100–250 V AC, with a separate 24 V DC control circuit for the logic side — keeps the control wiring isolated from the power circuit. The unit includes run, fault, by-pass, and overload signal relays, so you get status feedback without adding interface modules. ## Deployment context Main terminals are IP00 per IEC 60529 — that means the power connections are bare bus bars, intended for enclosure mounting where the panel provides the overall IP rating. The main circuit connects via bars with a 10.2 mm hole diameter; control wiring uses rigid 1 x 2.5 mm² terminals with a 0.5 N·m tightening torque. Communication is via a standard FieldBusPlug, which means it accepts the ABB fieldbus adapter modules for PROFIBUS, DeviceNet, or similar — no onboard protocol, but ready for a plug-in gateway.","metaTitle":"ABB PST175 1SFA894011R7020 Softstarter, 175 A In-Line, 90 kW","metaDescription":"ABB PST175 softstarter 1SFA894011R7020. 175 A in-line (90 kW at 400 V), 300 A inside-delta (160 kW).
