The GRZ series is a three-phase solid-state relay that controls electric heaters and industrial heating processes. The compact designs are ideal for electrical panels with limited space.
Electrical heating control
The current range for the GRZ series is 10A to 75A, and this controller has an efficient zero-crossing (ZC) mode.
Two or three-leg load control
The GRZ series is configured to control two or three legs of a heating circuit. While three-leg breaks are commonly used, the two-leg option generates less heat in the electrical panel.
Diagnostics
The GRZ series monitors and prevents system failures, and it reduces the risk of costly downtime and material waste. To improve uptime, this controller has a silicon-controlled rectifier (SCR) over-temperature alarm, it monitors line voltage for failures, it has fuse break protection, and load interruptions are monitored and displayed clearly for users.
