GRB type overheat protector for motor

    GRB overheat protector is designed as a matching for PTC thermistor of MZ6. When the temperature of the motor coil (or some point on the coil) is over heat, PTC resistance rises. The signal transmits to GRB overheat protector, making a transition in the protector relay. Then the main current cut off to protect the motor.

    1. Advanced technology
    2. Safety and stady
    3. High reliability
    4. Energy conservation (self consumption power is 0.8VA)
    5. The shut down temperature can be precisely worked out
