Miniature Circuit Breakers (MCB) are designed to automatically isolate the circuit if a fault is detected. The purpose is to provide protection against damage which can be used by shortage or overload.
What is an MCB?
A circuit breaker is a safety device made to protect electrical circuits from damage caused by overcurrent. Its primary function is to interrupt current flow to prevent and possible fires to protect equipment.
We have a wide range of MCBS to suit any installation requirement. We have B Curve and C Curves and a variety of amp ratings available to purchase today for next day delivery.
Miniature Circuit Breakers is the abbreviation for Miniature Circuit Breakers. The primary function of an MCB is to protect an electrical circuit. If there are abnormal or defective conditions, MCBs are meant to immediately shut down the electrical circuit.
What do MCBS protect against?
The electric circuit is protected by MCBs from overcurrents, overloads, and short circuits. Electrical wires can be damaged by overloads and short circuits. MCBs are utilised to increase the cable's lifespan.
What can cause MCBs to trip?
There are many factors which can cause an MCB to trip including overloading the electrical circuit, faulty wiring and short circuits.
Where are B curve MCBS used?
B curve MCBS are commonly installed in domestic environments. Circuits with equipment that does not produce surge current, such as lighting and distribution circuits, are protected by B' Curve MCBs.
Where are C curve MCBS used?
C curve MCBS are commonly installed in commercial and residential environments. The 'C' Curve MCB is used to safeguard circuits containing surge currents.
