Miniature Circuit Breakers 4 Series Thermal operation Occurs when the bi-metal strip (1), is heated by the overload current and deflected. This trips the tripping lever which, with its spring action (2), causes the contacts (3) to open. Magnetic tripping Is achieved by utilising the solenoid (4), which causes the armature (5) in conjunction with the mechanical action of the spring (2) to open the MCB’s contacts. Note: The splitter plates (6) break up the ionised gas as the switch mechanism opens, extinguishing the arc. Top or bottom connection Clipsal MCBs allow line or load cables to be connected...
