Sensata/Crydom SSR Panel Mount Solid State Relay 50A 660V

The Sensata/Crydom H12WD Series is a robust, panel-mount solid state relay engineered for demanding industrial applications. Featuring a redesigned housing with anti-rotation barriers, it ensures secure and stable installation. Its SCR (Silicon Controlled Rectifier) output is specifically designed to handle heavy industrial loads with high reliability.

This SSR offers versatile switching with selectable zero-voltage or instantaneous turn-on outputs, providing flexibility for different load types to minimise electrical noise and inrush currents. Key construction advancements include an improved SEMS screw and washer for superior terminal connection, a direct bond copper substrate for excellent thermal performance, and a direct power lead frame for efficient current carrying.

Enhanced Design & Compliance

The relay boasts an epoxy-free design, enhancing long-term reliability and thermal cycling performance. It is EMC compliant to Level 3, ensuring minimal electromagnetic interference in sensitive environments. With a low OFF-state leakage current, it operates snubberlessly, simplifying circuit design. Control is achieved via a straightforward DC input, with a wide control voltage range for compatibility with various systems.

Critical Safety Notice
