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.
