RCCB RCCB is a circuit breaker with an interesting feature that prevents people from electrocution. The full form is Residual Current Circuit Breaker. This type of circuit breaker operates by checking the balance between the current flow through the wire and the current flow back through the neutral line. MCB, MCCB, RCCB , & ELCB are circuit breakers but designed for serving a different purpose. Let's understand the difference among all in detail here. A Residual Current Circuit Breaker (RCCB) is an electrical protecting device that protect against the leakage current and prevents electric shock and fire hazards in an electrical circuit. RCCB detect the leakage current and fastly trip the circuit by cutting off the power supply. It is easy to install. Function: It detects the difference between the live (phase) and neutral currents. If there’s an imbalance (due to current leakage to earth), it trips the circuit, cutting off the power ... Understanding the full form of RCCB (Residual Current Circuit Breaker), its working principle, types, installation guidelines, and its critical role in electrical safety.
