FIELD: electricity.
SUBSTANCE: fast-acting automatic circuit breaker comprises a magnetic conductor of a magnetic latch, an anchor of a magnetic latch, two contacts, a pull-in electromagnet, a spring of contact pressing, disconnecting springs and a current sensor. Contacts are made as movable, with a drive of one contact from the anchor of the magnetic latch, and of the second contact - from a connecting pull-in electromagnet via a spring of contact pressing.
EFFECT: higher reliability and reduced dimensions due to simplification and reduction of a number of mechanism links.
