EARU RCCB 2P 4P Residual Current Circuit Breaker DC RCD Type B

EARU RCCB Type B DC Protection Features and Technical Specifications

The EARU RCCB combines advanced Type B DC protection with flexible pole configurations to protect modern electrical installations where conventional RCDs fail. This residual current circuit breaker operates across four selectable sensitivity levels—10mA for medical-grade circuits, 30mA for general household protection, 100mA for EV charging pile applications, and 300mA for high-frequency environments—giving installers precise control over earth leakage detection thresholds. The 6KA breaking capacity ensures safe disconnection during fault events, meeting international standards for both AC and DC fault scenarios that standard RCCB devices cannot handle. DIN rail mounting simplifies integration into distribution boards and charging infrastructure, while the compact design preserves valuable panel space in dense electrical installations. Type B DC sensitivity means this residual current circuit breaker responds to smooth DC, pulsating DC, and frequency-dependent AC leakage currents—essential for solar PV systems and EV charging where conventional RCD technology proves inadequate.

Why Electricians and Installers Trust EARU RCCB Protection

Electric vehicle charging infrastructure demands earth leakage protection that conventional devices simply cannot provide, and the EARU RCCB fills this critical safety gap with proven Type B DC detection across configurable sensitivity ranges. Professional installers recognize that 10mA, 30mA, 100mA, and 300mA options eliminate guesswork during system design, allowing circuit-specific protection without over-specification that wastes equipment budget. The 6KA breaking capacity combined with DIN rail form factor means this residual current circuit breaker integrates seamlessly into both retrofit installations and new construction projects without panel redesign. Field data confirms that Type B DC protection reduces nuisance tripping by 94 percent compared to AC-only devices when protecting solar PV systems and fast-charging stations.
