Description:

7MP current and temperature dual protector is a protection element with both over-current and temperature-sensitive dual protection functions. It can precisely control the damage of the motor caused by the blocking or over-current. The auxiliary heating plate in the thermal protector is matched with the bimetallic plate. The utility model has the function of accurately controlling the overloading current escape time. When (motor, transformer...) in the current is too large or the blocking current exceeds the set value of the thermal protector, the protector can instantly cut off the circuit, so that electrical protection. When the temperature of the protected appliance drops to the safe temperature, the contact of the thermal protector automatically closes and resets. Re-turn on the power supply, electrical resume work.
