Rccb or rcd is the new name that specifies current operated (hence the new name to distinguish from voltage operated). the new rccb is best because it will detect any earth fault. the voltage type only detects earth faults that flow back through the main earth wire so this is why they stopped being used. The main different between mcb and mccb is the interrupt current rating which is up to 1800 amperes for mcb and 10k – 200k amperes for mccb. the following table shows the comparison and major differences between mcb and mccb for different characteristics. keep in mind that both mcb and mccb are classified as low voltage circuit breakers and.

What is mcb 2. what is mccb 3. difference between mcb and mccb 4. what is rccb 5. what is elcb 6. difference between rccb and elcb. mcb, mccb, rccb, and elcb are circuit breakers but all of them are designed for serving a specific purpose. before knowing about the difference among all, let’s get to know about them a little bit. what is mcb. A tripping circuit leads to the breakage of the circuit in cases of abnormal current flow. while an mcb has a fixed tripping circuit, mccbs come equipped with movable tripping circuits. while an mcb can have up to 3 poles, mccbs often have up to 4 poles. ‘poles’ refers to the number of safety and switching phases the mcb or mccb circuit. 2). medium voltage circuit breaker and. 3). high voltage circuit breaker. in this post, discuss in detail about various types of low voltage circuit breaker as follows: miniature circuit breaker (mcb) moulded case circuit breaker (mccb) motor protection circuit breaker (mpcb) residual current circuit breaker (rccb). Mcbs and mccbs are circuit breakers with varying current ratings, suited for different load capacities. rcb, rcd, rccb, and rcbo, on the other hand, focus on protecting against residual currents and electric shock. while an rcd provides standalone protection, an rcbo combines the functionalities of an rcd and an mcb or mccb.
