Electrium 50/10 Single Pole 10A Type C MCB with magnetic/hydraulic mechanism which is unaffected by temperatures related to extreme climates. It meets BS EN 60898 standard. 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 coil is unable to overcome the restoring force of the time delay spring, and the iron slug remains at the far end of the tube. When an overload occurs, the magnetic field pulls 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 gap in the magnetic circuit is reduced, so increasing the pull on the armature until it moves and the breaker is tripped. If a large overload or short circuit occurs, the magnetic field generated is much greater and the armature moves without having to wait for the slug to reach the end of the tube. In this way instantaneous tripping occurs.
