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.
The MCB is an electromagnetic device that protects electrical wires and loads from inrush current, preventing fires and other electrical risks. MCB is safer to handle, and it recovers power rapidly. For overloading and transient circuit protection in residential applications, the MCB is the most popular choice. MCBs are extremely quick to reset and require no maintenance. The bi-metal complementary idea is used in MCBs to defend against overflow current and short circuit current.As a way to ideal meet up with client’s desires, all of our operations are strictly performed in line with our motto “High quality, Competitive Cost, Fast Service” for Suppliers 63A 2p 2pole MCB Miniature Circuit Breaker for Solar PV Power System, We with great passion and faithfulness, are ready to provide you with best solutions and striding ahead along with you to make a shiny potential.
