China OEM High Quality 10ka 2pole AC Type MCB Miniature Circuit Breaker

Short Description:

CJM7-125 Miniature circuit breakers (MCBs) ensure electrical safety in homes and similar situations, such as offices and other buildings as well as for industrial applications by protecting electrical installations against overloads and short circuits. Once a fault is detected, the miniature circuit breaker automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. Warranting reliability and safety for people and assets, MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection. normally the rated current is 63, 80, 100A and rated voltage is 230/400VAC. frequency is 50/60Hz. according to IEC60497/EN60497 standards.

What is MCB?

Miniature Circuit Breaker (MCB) is a type of circuit breaker that is small in size. It immediately cuts off the electrical circuit during any unhealthy condition in the electricity supply systems, such as an overcharge or a short-circuit current. Although a user may reset the MCB, the fuse may detect these situations, and the user must replace it.

When an MCB is subject to continuous over-current, the bimetallic strip heats up and bends. An electromechanical latch is released when the MCB deflects the bi-metallic strip. When the user connects this electromechanical clasp to the working mechanism, it opens the microcircuit breaker contacts. Consequently, it causes the MCB to switch off and terminate the current flowing. The user should individually switch on the MCB to restore the current flow. This device guard against defects caused by excessive current, overload, and short circuits.We are going to dedicate ourselves to providing our esteemed buyers together with the most enthusiastically thoughtful products and services for China OEM High Quality 10ka 2pole AC Type MCB Miniature Circuit Breaker, We have been wanting ahead to setting up cooperative associations along with you.
