Abstract (en)
[origin: CA2019492A1] LIMITING CIRCUIT BREAKER EQUIPPED WITH AN ELECTROMAGNETIC EFFECT CONTACT FALL DELAY DEVICE A limiting circuit breaker comprises an electrodynamic repulsion contact system, and an electromagnetic latch arranged in the vicinity of the contact system, and electrically insulated from the latter. Actuation of the latch to the active position results from the action of the electromagnetic field due to a short-circuit current flowing in the pole, so as to temporarily keep the movable contact open after repulsion. The latch is equipped with a pair of ferromagnetic brackets, and with a spring blade to return to an inactive position.
