EARU ELCB 2P 4P DC RCCB Residual Current Circuit Breaker

EARU ELCB DC RCCB Specifications and Earth Leakage Protection

The EARU ELCB 2P 4P DC RCCB features dual pole and four pole configurations designed specifically for DC circuit protection where standard AC breakers fail. Selectable sensitivity ratings of 10mA, 30mA, 100mA, and 300mA allow precise tuning for electric vehicle charging piles, solar PV systems, and battery energy storage applications. Type B RCD technology detects both sinusoidal and pulsating residual currents that conventional devices miss, a critical capability for DC installations. The 6KA breaking capacity provides reliable fault protection across residential charging stations and commercial solar arrays without nuisance tripping. DIN rail mounting integrates seamlessly into existing electrical panels, control cabinets, and distribution boards where space is limited.

Why Choose EARU ELCB for DC Circuit Protection

Electric vehicle charging infrastructure demands fast response time to leakage currents, and the EARU ELCB delivers trip response in milliseconds when fault conditions develop. Electricians and installers specify this model for solar PV systems because the adjustable sensitivity ratings prevent false alarms caused by normal inverter switching transients. The dual pole option protects single circuits while the four pole variant safeguards three-phase DC systems used in larger industrial applications. Test data confirms operation across -20°C to +60°C ambient temperature ranges, ensuring performance in rooftop installations and outdoor charging locations.
