RCBO (Residual Current Circuit Breaker

RCBO (Residual Current Circuit Breaker with Overcurrent protection) integrate the functions of an RCCB and an MCB, providing protection against earth leakage and overcurrent (overload and short-circuit) in a single device. ETEK Solar’s Type B RCBOs offer comprehensive protection for photovoltaic systems, EV chargers, and other demanding applications, with full sensitivity to AC, pulsating DC, and smooth DC residual currents.

EKL5-63B Type B RCBO—Professional Residual Current Circuit Breaker for AC, Pulsating DC, and Smooth DC Leakage Protection

The EKL5-63B Type B RCBO delivers comprehensive protection for modern electrical systems by combining overload, short-circuit, and advanced residual current detection in one compact device. Unlike standard RCBOs, this type B unit detects AC, pulsating DC, and smooth DC earth leakage, making it the ideal choice for installations with EV chargers, solar inverters, and variable frequency drives. EKL5-63B ensures optimum safety and complies with IEC 62423 and IEC/EN 61009-1 standards.
