Earth leakage circuit breakers, commonly known as residual current devices (RCDs) or residual current circuit breakers (RCCBs), are essential protective devices designed to detect leakage currents to earth and automatically disconnect the circuit to prevent electric shock or fire hazards. These devices are characterized by their rated residual operating current (IΔn), typically ranging from 10 mA to 300 mA, rated voltage (e.g., 230/400 V AC), and number of poles (2P, 3P, or 4P). They are available in Type AC (for sinusoidal alternating residual currents), Type A (for pulsating DC residual currents), and Type B (for smooth DC residual currents), ensuring compatibility with modern electronic loads. The breaking capacity and response time are critical parameters, with instantaneous or time-delayed (S-type) versions for selectivity. Mounting options include DIN rail for modular installations or panel-mounted for industrial enclosures.

Earth leakage circuit breakers are deployed across residential, commercial, and industrial sectors to ensure electrical safety. In residential settings, they protect circuits for sockets, lighting, and wet areas like bathrooms and kitchens. In commercial buildings, they safeguard office equipment, HVAC systems, and public lighting. Industrial applications include protection of machinery, motor circuits, and temporary power distribution on construction sites. They are integral to electrical panels, distribution boards, and automation systems, particularly where high sensitivity to earth faults is required to meet safety standards like IEC 61008 and IEC 61009.

Key subcategories include RCCBs (residual current circuit breakers without overcurrent protection) and RCBOs (residual current circuit breakers with overcurrent protection). Common article codes follow patterns like RCCB-2P-40A-30mA or RCBO-4P-63A-300mA, where the code specifies poles, rated current, and sensitivity. For example, a 4P RCCB with 63 A rated current and 300 mA sensitivity is coded as RCCB-4P-63A-300mA. Other variants include Type A and Type B devices for specific residual current profiles. These codes are standardized across manufacturers for easy identification.
