Datos técnicos

Panorámica
The GRZ-H 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-H series is 10A to 75A, and this controller has an efficient zero-crossing (ZC) mode.
Two or three-leg load control
The GRZ-H 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-H 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.
