General Purpose – WSES Series

Efficient Soft Start Control Panel System
The World Start Efficient System (WSES) combines a reduced-voltage chassis starter, ancillary components, and controls to provide a single, cost-effective system suitable for operating equipment with basic performance requirements, such as pumps, fans, or motors.

The WSES features an intuitive parameter setup and multiple feature sets. Operationally the β€œAt Speed / Run Bypass” mode takes over the motor load control from the SCR units after the motor is at full speed. This feature reduces panel heat during RUN mode. Emergency full-voltage bypass is not part of this system.

The secure lockable panel, with padlock disconnect, protects the ancillary components: terminal block, panel surge protection with the main circuit breaker, pilot devices, and other options, and provides a maintenance-friendly yet compact design.
