Crouzet 84137120 GN Series Single Phase SSR – 50A 660VAC 4-32VDC

The Crouzet GN Series Solid State Relay is a high-performance electronic switching solution designed for demanding industrial applications. Unlike traditional mechanical relays, this SSR has no moving parts, ensuring silent operation, ultra-fast switching, and an exceptionally long lifespan. It features Zero-Cross switching to minimize electrical noise and inrush current, making it ideal for controlling resistive loads like heating elements or inductive loads like motors. With integrated overvoltage protection and an IP20 touch-safe cover, it offers superior safety and reliability in a compact “hockey puck” design.
