    Gefran GRZ-H Three-phase solid state relays, 10 A to 75A

     

    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.
