ABB PSE170-600-70 model belongs to the PSE series of soft starters.

Product Description

ABB PSE170‑600‑70 is a compact soft‑starter from PSE series for three‑phase asynchronous motors. It achieves smooth motor start‑up and soft‑stop to limit inrush current and reduce stress on power network and mechanical equipment. Built‑in bypass contactor closes after motor ramp‑up to minimize internal power loss. Comprehensive protection covers motor overload, phase loss, phase unbalance and unit over‑temperature. Local keypad allows configuration of starting voltage, ramp‑up time and soft‑stop parameters. Cabinet‑mount design for fans, pumps, compressors and similar loads, suitable for OEM integration, spare‑part replacement and retrofit of legacy soft‑starting equipment.
