The main circuit breaker is composed of the operating mechanism, the contact, the protection device (various release units), the arc-extinguishing system, etc. The main contact is operated by manual operation or electric closing. The main contact in the closing position on the over-current release of the coil and thermal release of the thermal components and the main circuit in series, undervoltage release of the coil and power in parallel when the circuit short circuit or serious overload , The overcurrent releases the armature of the tripping device so that the free tripping mechanism moves and the main contact opens the main circuit.When the circuit is overloaded, the thermal element of the thermal release heats the bimetal to bend, When the circuit is under voltage, the armature release of the undervoltage release also activates the free trip mechanism.
For the line protection, motor protection, combined with the starter, non-automatic circuit breakers, three-phase power distribution system into the line and outlet circuit breakers; motors, generators, transformers and capacitors switching, protection; Of the main switch; emergency stop switch with a trip with a voltage trip in conjunction with the circuit breaker
Micro-circuit breaker, referred to as MCB (Micro Circuit Breaker), is the construction of electrical terminal power distribution device cited the most widely used in a terminal protection appliances for 125A the following single-phase, three-phase short circuit, overload, overvoltage protection , Including single-pole 1P, two-pole 2P, three-pole 3P, four-pole 4P and so on.
