FIELD: electricity. ^ SUBSTANCE: invention refers to electric engineering, in particular to protective switching equipment. The circuit-breaker contains base, movable and fixed contacts, switching-on and holding electromagnets with magnetic conductor, coil and armature, opening spring. Switching-on and holding electromagnets are pivotally mounted on the base, and the armature of switching-on electromagnet at the same time is the armature of holding electromagnet. In this device movable contact is pivotally mounted on the armature. Free end of movable contact is spring-loaded by spring. Additionally, operational reliability of circuit-breaker and processability during actuator manufacturing are improved. ^ EFFECT: reducing time of switching off and decrease in dimensions of actuator, improvement of circuit-breaker operational reliability of and processability during manufacturing. ^ 3 dwg |
