MCCB

A molded case circuit breaker (MCCB), is a type of electrical protection device that is applicable for a wide range of voltages, and frequencies of both 50 Hz and 60 Hz. MCCB can have current ratings of up to 2,500 amperes, and its trip settings are normally adjustable. MCCBs tend to be much larger than MCBs. As with most types of circuit breakers, and MCCB has three main functions:

Protection against overload – currents above the rated value that last longer than what is normal for the application.
Protection against electrical faults – During a short circuit, there are extremely high currents that must be interrupted immediately.
Switching a circuit on and off – This is a less common function of circuit breakers. But, they can be used for that purpose if there isn’t an adequate manual switch.

We make available various ranges of circuit breaker devices for industrial applications that offer customized solutions based on different load requirements. Moulded Case Circuit Breakers (MCCBs) are available in a wide range of ampere and pole requirements.
