Tips: The main components of the miniature circuit breaker

A miniature circuit breaker (MCB) is a crucial safety device in electrical circuits, designed to automatically disconnect the circuit in the event of overload or short circuit. Its main components include:

Frame: The outer casing that houses all the components, made from insulating materials to prevent electrical contact.
Contact System: Includes moving and fixed contacts that open and close the circuit. When a fault occurs, the contacts separate to interrupt the flow of electricity.
Trip Mechanism: This includes two types—thermal and magnetic. The thermal trip uses a bimetallic strip that bends with heat caused by an overload, while the magnetic trip uses an electromagnet to react to the sudden surge of current during a short circuit.
Arc Chute: A device used to quench the electrical arc formed when the contacts separate, preventing the arc from damaging the micro circuit breaker and ensuring safe operation.
Terminal Block: The points where the mini MCB connects to the incoming and outgoing electrical circuits.

It worked as required.

I used this 2 pole miniature circuit breaker for solar connection. It worked as required. It mounts to a standard track. Screws make connection firm and lever easy to open and close. It is a good choice for solar panel.
