MCB means Miniature Circuit Breaker — it is used for upto. 100Amps in the motor feeders. MCCB menas Moulded case Circuit Breaker — it is used for. 25oAmps to 800Amps in the motor feeders. ELCB means Earth Leakage Circuit Breaker — it is used to.

What is the difference between MCB and MCCB PDF?

“MCB” stands for “Miniature Circuit Breakers”, while “MCCB” is “Molded Case Circuit Breaker.” Judging from their power capacities, the MCB is mainly used for low-energy requirements, like home wiring or small electronic circuits. On the other hand, the MCCB is more suited in providing energy for high-power equipment.

What is difference between MCB and MCCB?

The MCB stands for Miniature circuit breaker whereas the MCCB stands for moulded case circuit breaker. The tripping circuit of the MCB is fixed whereas in MCCB it is movable. When over current flows through the MCB and MCCB it shuts off the switch and hence protects the equipment from damage.

What is difference between MCB and RCB?

The main difference between MCB, RCCB, and Isolators Isolators are generally used in power system while on the other hand, MCB is the circuit breaker. Whereas, on the other hand, residual current device protects the life-threatening problems. RCCB detects the leakage current and protects from the electric shock.

What is MCB full form?

MCB stands for Miniature Circuit Breaker. It automatically switches OFF electrical circuit during any abnormal condition in the electrical network such as overload & short circuitconditions. When it comes to house applications, MCB is the most preferred choice for overload and short circuit protection.

Why RCCB is used?

Residual Current Circuit Breaker (RCCB) is a differential current sensing device used to protect a low voltage circuit in case of a leakage fault. The RCCB provides protection from small current leakage arising due to accidental touch by human being or insulation failure, which is not possible by MCB or fuse alone.

What does ELCB stand for in electrical category?

It is essential lifesaving equipment used to protect the human body from electrical and is mandatory in many states for domestic installation. ELCB stands for Earth Leakage Circuit Breaker. They have the same function as RCCB but are voltage sensor devise. However, this is an old technology & is not in common use.
