GRZ-H Three-Phase Solid State Relays (SSR) for Industrial Heating Applications

The GRZ-H series of three-phase solid state relays (SSR) is the ideal solution for controlling electric heaters in industrial heating applications. Compact, scalable, and available from 10A to 75A, the series features efficient Zero Crossing (ZC) control for reliable and stable performance.

In applications where full three-phase control is not required, the two-phase GRZ-H models provide safe load control while reducing heat dissipation by up to 33%, lowering electrical panel cooling requirements and operating costs.

To ensure production continuity and prevent costly downtime, the GRZ-H series integrates advanced protection features, including:

• SCR overtemperature alarm

• Line voltage loss detection

• Fuse failure detection

• Load break monitoring

GRZ-H solid state relays are part of the wide range of process control components available from Mit.D, alongside temperature probes, thermocouples, and industrial control solutions.
