WebDifference Between ELCB and RCCB: ELCB stands for Earth Leakage Circuit Breaker and RCCB stands for Residual Case Circuit Breaker. ELCB and RCCB is the most confusing terms in electrical. RCCB is an updated version of ELCB. Now a days ELCB is completely replaced by RCCB. In this article, We are going to see 5 Basic difference between ELCB and RCCB. WebEdvard說殘餘電流斷路器(RCCB)基本上具有殘餘電流跳脫特性之機械開關，當漏電流洩露至大地時，該斷路器將斷開電路以保護人員安全。 而具過載保護之殘餘電流斷路器(RCBO)其實就是殘餘電流斷路器(RCCB)與模殼斷路器(Molded Case Circuit Breaker, MCCB)的組合體，兼具接地故障電流、過電流及短路電流啟斷能力。

Web(ii) RCD Type A: RCD tripping on alternating sinusoidal residual current and on residual pulsating direct current, suddenly applied or smoothly increasing. NOTE 1: For RCD Type A, tripping is achieved for residual pulsating direct currents superimposed on a smooth direct current up to 6 mA. A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that quickly breaks an electrical circuit with leakage current to ground. It is to protect equipment and to reduce the risk of serious harm from an ongoing electric shock. … See more RCDs are designed to disconnect the circuit if there is a leakage current.
