What is the material of MCB?

Construction of MCB The metal or current carrying parts are made up of electrolytic copper or silver alloy depending on the rating of the circuit breaker. As the contacts are separated in the event of an overload or short circuit situation, an electric arc is formed.

How is MCB manufactured?

MCBs are manufactured in different pole versions such as single, double, triple and four pole structures with different fault current levels. Mostly, MCBs are linked to give two and three-pole versions such that a fault in one line will break the complete circuit and hence complete circuit isolation are provided.

What is miniature in MCB?

An MCB is an automatically operated electrical switch. Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current. They are designed to trip during an overload or short circuit to protect against electrical faults and equipment failure.

Which plastic is used for circuit breaker?

PVC is widely used to insulate electric wiring, while thermosets (which can withstand high temperatures) are used for switches, light fittings and handles.

What is a mini breaker?

A miniature circuit breaker (MCB) is an Electrical Switch which automatically switches off the electrical circuit during an abnormal condition of the network means in overload condition as well as faulty condition.

What is electric plastic?

Electronic plastics like polycarbonate and ABS are used in all sorts of modern electronics. Cell phone casings, for example, are often made of chemically-treated polycarbonate to give them better scratch and impact resistance.

What plastic are electrical plugs made of?

Although both ABS and urea-formaldehyde are used for plugs, they are in fact used for slightly different applications. In addition, ABS is used for one piece moulded plugs which prevent access by the user whereas urea-formaldehyde is used for two piece plugs that can be fitted by users.
