Product Overview
The PSR37-600-70 belongs to ABB’s PSR series of compact soft starters, tailored for applications requiring space-efficient solutions without compromising performance. Rated for 18.5 kW motors (400V) or 22 kW motors (500V), it ensures smooth acceleration/deceleration, minimizing mechanical stress on equipment and electrical networks.

Key Features:

Soft Start/Stop: Gradually ramps motor voltage to eliminate inrush currents, reducing wear on couplings, belts, and gears.

Energy Saving Mode: Automatically reduces motor voltage during light loads to cut energy consumption.

Integrated Protection: Safeguards motors against overloads, phase failure, and thermal overload.

Compact Design: Screw-mounted installation with front-facing terminals for quick wiring.

Wide Temperature Range: Operates from -20°C to 65°C, adapting to harsh industrial environments.

Case Study: A cement plant reduced motor maintenance costs by 40% after replacing star-delta starters with PSR37-600-70 units, citing smoother operation and extended equipment lifespan.
