Mcb micro circuit breaker.

An electrical circuit breaker is a switching device that can be operated automatically or manually for controlling and protecting the electrical power system and the electrical devices connected to it. Mcbs are typically rated up to a current up to 125 a do not have adjustable trip characteristics and can be thermal or thermal magnetic in operation. With rated current up to 3000 a these breakers interrupt the arc in a vacuum bottle. These can also be applied at up to 35 000 v.

This means that the flow of electricity is cut off to keep your circuits. Under overload conditions the strip bends far enough to activate the breaker s trip mechanism. Miniature circuit breakers can be used for the protection of lighting house electronic devices and equipment with low short circuit currents. Thermal breakers use an internal bi metallic strip that bends according to the amount of current passing through it.

Mcb are available in 1 pole 2 poles 3 poles 4 poles and current rating from 0 5a up to 125a. Rcd residual current device rccb residual current circuit breaker. Plug in 1p 10ka miniature circuit breakers. An mcb or miniature circuit breaker is an electromagnetic device that embodies complete enclosure in a molded insulating material.

A miniature circuit breaker mcb automatically switches off the electrical circuit during an abnormal condition of the network means in overload condition as well as faulty condition. A miniature circuit breaker mcb is an automatically operated electrical switch used to protect low voltage electrical circuits from damage caused by excess current from an overload or short circuit. Type selection and fault judgment of miniature circuit breakers 3. The circuit breaker trips when too much electricity flows through it or when it cannot handle the excess current load.

It senses earth leakages and residual currents and ensures protection against electric shock. The miniature circuit breaker is a protection device that prevents damage to an equipment circuit on the event of an overload or short circuit faults. Residual current circuit breakers are devices that protect against electric shock. Nowadays we use an mcb in a low voltage electrical network instead of a fuse.
