  • Clapper-type electromagnet assembly having v-shaped air gap for use in a circuit breaker trip unit
    Publication number: 20020171519
    Abstract: An electromagnet assembly 200 for a circuit breaker trip unit includes a yoke 222, an armature 218 mounted for movement with respect to the yoke, and a coil 224, mounted with respect to the yoke for generating a magnetic field when energized with electrical current. The yoke and armature have complimentary male and female edges defining a working air gap C therebetween. When the coil 224 is energized, the magnetic field pulls the armature 218 towards the yoke 222 at a beginning of a stroke of the armature reducing the working air gap until the armature is seated at the yoke at an end of the stroke of the armature.
