- Packed unassembled with plate, strike, fasteners, and spanner wrench. - May be used with carpet or threshold application by omitting face plate. - Spring loaded plunger returns to floor or threshold level anytime flushbolt is retracted, eliminating the need to clean out the bottom strike. Date.
MCB is miniature circuit breaker which is thermal operated and use forshort circuit protection in small current rating circuit in branches of panel boards for small loads.MCCB moulded case circuitbreaker and is thermal operated for over load current and magnetic operation forinstant trip in short circuit condition.he main differences are The MCCB is equipped with tripping coil and can give a signal. The protection board of MCCB is more developed. It has L-L, L-G, thermal, and instantaneous setting, while MCB doesn't has those facilities. MCCB is usually used for high current application/.
This page describes a simple circuit breaker. See the next page for the residual current circuit breaker. The circuit breaker acts as a safety device in the same way as a fuse. Circuit breakers that are used at the distribution board in houses are called MCBs (minature circuit breakers).The distribution board is also called the consumer unit.The MCBs disconnect the supply if too large a current flows.
