Frequently Asked Questions
What is the difference between an MCCB and an MCB?
An MCCB is a larger and more robust circuit breaker than an MCB. MCCBs are used for higher current ratings and more demanding applications, while MCBs are used for lower current ratings and simpler applications.
What is the difference between a circuit breaker and a fuse?
A circuit breaker is a switch-like device that interrupts the flow of current in an electrical circuit when an overload or short circuit is detected. A fuse, on the other hand, is a protective device that melts or blows when the current exceeds a certain level.
How do I maintain an MCCB?
MCCBs maintenance includes cleaning, inspecting, testing and calibrating them and their components.
