What is MCCB?

MCCB is basically known as Molded Case Circuit Breaker. And Molded Case Circuit Breaker is a type of low-voltage circuit breaker. MCCB are used for higher power requirements like industrial or large commercial applications. The MCCB can be used up to 2500 A. This makes it possible to use MCCB in large applications. Interruption rating of MCCB can go up to 200000 A. MCCB have various tripping functions such as continuous ampere, long time delay, short time pickup, short time delay, instantaneous pickup and ground fault pickup. These are adjustable trip functions, which means you can set trip parameters to suit your needs; Thus providing the user with more flexibility to design the circuit. MCCB is enclosed in a molding or housing of molded material and hence known as molded case circuit breaker.
