What is a Molded Case Circuit Breaker?

A molded case circuit breaker (MCCB) is a type of breaker that protects electrical circuits from overcurrents arising from overload, short circuits, or faulty wiring. It is like a miniature circuit breaker (MCB), however, MCCB has higher features. Molded case circuit breakers have a higher current rating of up to 2500 amp and an adjustable … Read more

What is a Miniature Circuit Breaker (MCB)?

A miniature circuit breaker is a safety switch that protects an electrical circuit from overcurrent or power surge. It is a protective device that interrupts the circuit when there are high currents. The primary function of a miniature circuit breaker is to protect an installation or branch circuit against high current arising from overload or short … Read more

What is an Oil Circuit Breaker?

An oil circuit breaker is a type of breaker that uses oil as an insulation medium for arc extinction. It is an essential device in the power system that uses insulating oil as an arc quenching medium. Oil circuit breakers use fixed and moving contacts for in circuit protection in both substations and transformers Each … Read more
