Description

Molded Case Circuit Breakers (MCCBs) are essential protective devices designed to safeguard electrical circuits from overloads and short circuit conditions. Enclosed in a robust plastic casing, these breakers feature modular components, including auxiliary contacts and tripping devices, ensuring a compact and efficient structure. The MCCBs are primarily operated manually, though electric switches are available for larger capacities.

Available in two classes, Class A and Class B, these circuit breakers utilize different tripping mechanisms. Class B offers advanced three-stage protection, while Class A, using a thermo-magnetic tripping device, enjoys higher market popularity due to cost-effectiveness. The installation includes key components like contacts, an arc extinguishing chamber, and an operating mechanism, all designed with minimal maintenance in mind.

MCCBs can provide various protection modes, ranging from basic overload and short circuit functionality to sophisticated electronic units that include ground fault detection and selective chain capabilities. They represent a reliable solution for branch circuit protection, combining ease of use with advanced safety features.
