A residual-current device ( RCD ), residual-current circuit breaker ( RCCB) or ground fault circuit interrupter ( GFCI) [a] 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. [1] A residual current circuit breaker (RCCB) is an electrical safety device that detects and interrupts an electrical circuit when there is a leakage current to the ground. It protects people and equipment from electric shocks, fires, and other hazards caused by faulty wiring, insulation failure, or accidental contact with live parts.

The Residual Current Circuit breaker RCCBs are the safest device to detect and trip against electrical leakage currents, thus ensuring protection against electric shock caused by indirect contacts. Residual-current devices (RCDs) and Ground-fault interrupters (GFIs) by Chris Woodford. Last updated: January 6, 2022. Electricity is amazingly useful—but it can be amazingly dangerous too! Did you know that it takes only a fifth of a second for a strong electric current flowing through your heart to kill you? A Residual Current Circuit Breaker (RCCB) is essentially a current sensing device used to protect a low voltage circuit in case of a fault. It contains a switch device that switches off whenever a fault occurs in the connected circuit. Purpose of RCCB Residual current circuit breaker with overload protection (RCBO) This is a residual current device that has an MCB built in to it. Effectively, the RCBO is the equivalent of an RCCB + MCB. The main functions that an RCBO is able to provide are: Protection against earth fault currents;

Residual Current Devices help protect people and equipment against electrical shocks caused by indirect contact. RCDs work together with Miniature Circuit Breakers (MCB) or fuses, covering the whole system against potentially damaging thermal and dynamic stresses of any overcurrent. F200 series ground fault equipment protection (GFEPs) are. Residual Current Circuit Breaker with Over Current Protection (RCBOs) The range designed to ensure efficiency and protection RCBOs are commonly used in applications where there is the need to combine protection against overcurrents (overload and short-circuit) and protection against earth leakage currents. Residual Current Circuit Breaker RCCB works based on the principle of Kirchhoff's current law. The law states that the incoming current must be equal to the outgoing current in a circuit. RCCB thus differentiates the deviation in current values between live and neutral wires. A residual current circuit breaker (RCCB) detects earth leakage in a circuit. It monitors the difference between the current flowing through the phase and neutral wires. When there is an imbalance, it trips to protect against electrical hazards. This article covers an RCCBs design, working principle, types, and advantages and disadvantages.

Residual Current Circuit Breaker or RCCB is basically a gadget that senses current and disengages any low voltage (uneven current) circuit whenever a fault occurs. The main purpose of installing a Residual Current Circuit Breaker fundamentally is to protect people from electric shocks or death caused by them. The residual current device (RCD) or residual current circuit breaker (RCCB) enables the rapid disconnection of electricity, thereby avoiding prolonged and potentially serious shocks. An RCD device complete with overcurrent protection is called an RCBO, or residual current circuit breaker with overcurrent protection.
RCCB is named as Residual current circuit breaker because of it protects against residual current. Residual current means flow of leakage current between live conductor to earth. Current can flow in two different path, one is neutral and another one is earth. A Residual Current Circuit Breaker, commonly known as an RCCB or an RCD (Residual Current Device), is an electrical device designed to protect against electrical shocks and ground faults. It detects the imbalance of current flowing between the live and neutral conductors and interrupts the circuit when a fault is detected.

A residual current operated circuit-breaker without integral overcurrent protection is a type of residual current device which is not equipped with integral overcurrent protection. The RCCB must therefore be protected against both overloads and short-circuits by overcurrent protection devices, which are circuit-breakers and fuses. A Residual Current Circuit Breaker (RCCB) is an important safety measure when it comes to protection of electrical circuits. It is a current sensing device, which can automatically measure and disconnect the circuit whenever a fault occurs in the connected circuit or the current exceeds the rated sensitivity.
