Why Choose the Carlo Gavazzi RSE4812-B Soft Starter?

The Carlo Gavazzi RSE4812-B is a compact and reliable three-phase AC semiconductor motor controller (soft starter) designed for controlled starting and stopping of induction motors. As part of the Carlo Gavazzi RSE series motor controller range, it provides smooth acceleration, reduced mechanical stress and improved motor performance in industrial automation applications.

This DIN rail mounted soft starter uses semiconductor switching technology with an integrated bypass function to provide efficient motor control while reducing the high starting currents associated with direct-on-line starting. The RSE series provides adjustable starting functions, LED status indication and built-in transient overvoltage protection for dependable industrial operation.

With a 12 A rated operating current, a 408–552 V AC operating voltage range and support for motors up to 5.5 kW at 400 V AC, the RSE4812-B is suitable for compact motor control systems requiring reliable soft starting and stopping.
