Description

Residual Current Circuit Breaker (RCCB) is designed as a protective safety device in electrical systems. It primarily detects leakage currents caused by ground faults and disconnects power to mitigate electrocution risks or fire hazards. **Core Specifications:** Rated for 40A load current with sensitivity calibrated at 30mA. Operates on a three-phase + neutral configuration to monitor all poles effectively, maintaining system integrity during fault conditions. **Functional Details:** Trips when differential current exceeds sensitivity threshold within milliseconds – ensures rapid interruption of circuit flow. Suited for domestic, commercial, and light industrial applications involving equipment prone to insulation failures or hazardous grounding issues. - Not compatible with DC circuits; works solely with AC systems. - Requires upstream overload/short-circuit protection; RCCB does not offer thermal/magnetic protection itself. - Suitable operating voltage range: 230V (phase-neutral), 400V (three-phase). - Should be tested periodically using built-in test function for reliable performance validation.
