MCB vs RCCB vs ELCB – The Difference

Device Protects Against Used For
MCB Overload & Short Circuit Circuit Protection
RCCB Earth Leakage & Electric Shocks Human Safety
ELCB Earth Leakage (Older Technology) Replaced by RCCB Today

While MCB switches provide protection against short circuits and overloads, RCCBs are designed to protect against electric shocks caused by earth leakage.

FAQs of MCB Switches

Q: How does an MCB switch work and what is it?

To avoid damage and danger, an automatic miniature circuit breaker, abbreviated as MCB Switch, switches off electric circuits upon occurrence of rare situations such as overloads and short circuits.

Q: What kind of MCB switch should be fitted in the house?

A Single Pole (SP) range MCB switch of 6A to 32A is usually used in domestic applications.

Q: How does an MCB switch differ from a fuse?

Unlike a fuse, which must be replaced after it blows, an MCB Switch can be reset after it trips. MCBs also provide faster and more reliable protection against electrical faults

Q: How do I choose the right MCB switch rating for my circuit?

The correct MCB switch rating depends on the circuit’s load, wire size, and application. Using the wrong rating can lead to nuisance tripping or inadequate protection, so professional guidance is recommended.

Q: What is the breaking capacity of an MCB Switch?

Breaking capacity refers to the highest level of fault current an MCB switch can safely cut off without getting damaged. It is usually measured in kiloamperes (kA) and indicates how much short-circuit current the MCB switch can handle in an electrical system.
