FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used as an actuator of the circuit breaker. Magnetic actuator (10) comprises magnetic core (16) with a groove (26a, 26b) for placing the coil (14), a movable plate (32) and the claws (34a, 34b), the position for fixing the coil (14) in the grooves (26a, 26b) the yoke (16). Catches (34a, 34b) comprise a position fixing part (38) projecting away from the yoke (16) over a portion (36a, 36b) of the coil (14) which is not included in the groove (26a, 26b). Yoke (16) comprises a central portion (18), two permanent magnets (20) and two sidewalls (22a, 22b).
EFFECT: technical result is to increase the efficiency.
