RCCB Definition: A Residual Current Circuit Breaker (RCCB) is defined as a safety device that detects and interrupts a circuit when there is a leakage current to the ground. Think of the RCCB as a much more advanced and sensitive version of the ELCB, offering even better protection against electric shock. Just like the ELCB , the RCCB keeps an eye on the electricity flowing in the live and neutral wires. 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. For any professional involved in sourcing or system design, the first question is always foundational: what exactly is the rccb full form? The answer is Residual Current Circuit Breaker . But this is more than just a technical term; it’s a life-saving device.
