FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to a protective switching device. The circuit-breaker has a base, movable and immovable contacts, including an electromagnet with a magnetic core and an armature, a holding electromagnet with a magnetic core and an armature, and an opening spring. The movable contact is directly attached to the armature of the holding electromagnet, and the magnetic core of the holding electromagnet has an inverted L-shape.
EFFECT: faster operation of the circuit-breaker and improved manufacturability.
