MCB(Mini Circuit Breakers) C50 Series

Product Description
The C50 MCB(mini circuit breaker,circuit breaker) employs the hydraulic/magnetic principle, the heart of which is a hermetically sealed tube filled with silicone fluid and containing a closely-fitting iron slug. In normal load conditions, the magnetic pull from the trip coiliron slug remains at thee far end of the tuube. When an overload occurs, the magnetic field puls the slug through the tube, the speed of travel being governed by the magnitude of the current. As the slug nears the end of the tube, the hap in the magnetic circuit is reduced, so increasing the pull on the armature until it moves adn the breakris os tripped. Lf a large overload or short circuit occurs, the magnetic field generated is much greater adnthe armature moves without gaving to wait for the slug toreach the end of the tube. In this way instantaneous tripping occurs.
