Difference between MCB and RCCB

Difference between MCB and RCCB

  • 01

    MCB Miniature Circuit Breaker

    MCB miniature circuit breaker wholesale is usually used to prevent damage from excessive current due to short circuit or overload.

  • 02

    RCCB Residual Current Circuit Breaker

    RCCB Residual Current Circuit Breaker is a current-operated safety device that quickly switch off electrical power when people get an electric shock or leakage current exceeds stipulated value, protecting personal and electrical equipment safety.

  • 03

    Use of MCB & RCCB

    The MCB's tripping circuit is fixed but is movable in the RCCB, and the MCB is largely used in low circuit current, while MCCB is used for the heavy current circuit

  • 04

    Main Difference

    The main difference between MCB and RCCB is that MCB is used to prevent short circuits and overload protection, and RCCB prevents earth leakage.

Hot Questions of RCCB Residual Current Circuit Breaker

  • What are the main advantages of residual current circuit breakers RCCB

    Residual Current Circuit Breaker provide the function of isolation switching and earth leakage protection of electrical circuits. And also provide the indirect protection of the electric current and provide the protection of the fire caused by the electrical circuit fault.

  • Does RCCB trip on overload?

    NO, they do not offer protection against current overloads.

  • How does an RCCB circuit breaker work?

    The primary objective of an RCCB device is to cut-off main AC and safeguard people from an electric shock. An RCCB will trigger and trip instantly, when it detects some current passing through an individual's body due to the body coming in contact with the mains AC line.
