What is MCCB?

MCCB is known as molded case circuit breaker. And this is a type of low-voltage circuit breaker. MCCB is generally used for high power requirement areas like industrial or large commercial applications. Also it can be used up to 2500 A. This enables the MCCB to be used in larger applications. MCCB's interrupt rating can go up to 200000 A. MCCB has various tripping functions like continuous ampere, long time delay, short time pickup, short time delay, instantaneous pickup and ground fault pickup. These are adjustable trip functions, meaning you can set the trip parameters to suit your needs; Thus providing more flexibility to the user to design the circuit. The MCCB is enclosed in a molding or housing of molded material and hence is known as a molded case circuit breaker.
