摘要:
A thermal protection mechanism for electric motors includes a pair of spaced contacts secured to an electrically insulated carrier. The contacts are engaged with a fusible electrically conductive pin made of solder that interposes along a current path to the windings of a motor. A thermal overload conditions causes the pin to fuse, thereby terminating operation of the motor.
