Difference Between Mcb And Mccb Electrical Tutorials 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. 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).

What Are The Full Forms Of Mcb Mccb Elcb And Sfu Quora 48 Off 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. 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. Voltage elcbs require proper earthing; current elcbs similar to rccbs. cost. generally more cost effective and widely available. voltage elcbs are typically less common and may be more expensive due to being older technology. mcb, mccb, rccb, & elcb are circuit breakers but designed for serving a different purpose. Mccb is a kind of electrical switch that safeguards the device from either short circuiting or overloaded conditions. and also, in mcb the interrupt rating is only 1800 amperes whereas mccb interrupts rating values range from 10k – 200k amperes.

The mcb is rated under low ampere up to 100 amps and interrupting ratings below 18,000 amps. whereas an mccb has an adjustable trip characteristic with current ratings of low values such as 15a to higher values up to 2,500a and interrupting ratings range up to 200,000a. trips on short circuit and overload. trip current is adjustable. For the connection of neutral, earth, and phase wire elcb is used. current leakage in any circuitry defines the operation of elcb. what is rccb. its full form is rccb normally employed in circuits where less value of voltages are employed. for separation of fault, there is a switch is linked. also, protect humans from electric shock.
