Description

An RCCB is a protective device designed to detect leakage currents in electrical systems and disconnect the circuit when a fault occurs. Its core function is to safeguard people and equipment by preventing electric shock hazards and reducing fire risks caused by earth faults. ### Electrical Characteristics - Type B design: Intended for detection of alternating, pulsating direct, and smooth DC leakage currents. - Current rating (In): Supports up to 40 A nominal load current. - Sensitivity: Rated at 300 mA for residual current threshold operation. - Short-time delayed operation: Reduces nuisance tripping during transient events in high-inrush or fluctuating-load systems. ### Physical Configuration - Poles: 4-pole model suitable for three-phase systems with neutral connection requirements. - Installation method: DIN rail mount compatible — standard fit into distribution boards. ### Technical Notes & Limitations - Not suitable for use without proper upstream overcurrent protection devices installed. - Must be tested periodically with the integrated test button as per maintenance schedules — failure to test reduces reliability. - Requires compatibility checking with system voltage levels; type B models are optimized for specific industrial setups including inverter-driven loads or EV chargers with DC components present. - Designed for low-temperature environments within defined operational limits; exceeding these may cause malfunctions over time.
