Why are miniature circuit breakers important?

Miniature circuit breakers (MCBs) are essential for electrical safety, acting as automatic switches that protect circuits from overloads or short circuits. They are crucial in both residential and commercial settings, ensuring the safe operation of electrical systems.

What is an MCB (Miniature Circuit Breaker)?

An MCB is a type of circuit breaker that is encased in molded insulating material, providing a mechanically strong and insulated housing. It consists of a fixed and a moving contact to which incoming and outgoing wires are connected.

What are the different types of miniature circuit breakers (MCBs)?

There are several types of Miniature Circuit Breakers (MCBs) based on different factors such as the current rating, voltage rating, and trip characteristic. Some common types of MCBs are: Thermal: This type of MCB trip is based on the temperature rise caused by the current flowing through the circuit.

What is a MCB breaker used for?

Residual Current Circuit Breaker (RCCB): This type of MCB is used to protect against electric shock and fire caused by earth faults. RCCBs monitor the current flowing in the live and neutral wires and trip the breaker when the difference exceeds a certain threshold. Isolation: This type of MCB is used as a switch to isolate a circuit.

What is a miniature circuit breaker?

Miniature circuit-breakers are only used at LV, mainly in domestic or light-industrial or commercial applications. In general they are used in the same applications as semi-enclosed or cartridge fuses and offer an alternative for protecting radial or ring circuits.

How does a bi-metallic circuit breaker work?

This deflection of the bi-metallic strip releases a mechanical latch. As this mechanical latch is attached to the operating mechanism, it causes to open the miniature circuit breaker contacts, and the MCB turns off thereby stopping the current to flow in the circuit. To restart the flow of current the MCB must be manually turned ON.
