7MP+PTC Current And Temperature Dual Protector Thermal Safety Cutoff For Motor Protection And Power Tools
Description:
7MP+PTCthermal protector is a PTC heating element with parallel contacts arranged on the 7MP protector. When the 7MP protector is in a closed state,PTC is in short-circuit state without voltage, when the protected object is abnormal, the protector contact disconnects, PTC has voltage heating, the heat makes the protector remain in the disconnection state, because the PTC resistance is above 10KΩ, the load is stopped. Only when the power supply is cut off, the contact of the PTC cooling protector can be reset automatically, and the power supply load can be switched on again to resume the running state.
