20A Mini RCBO – Type A, 1P+N, B Curve, 6kA, 30mA, DIN Rail Mount. Type: Mini/Compact RCBO. Why Choose an RCBO over an MCB?. While an MCB (Miniature Circuit Breaker) provides protection against overcurrent and short circuits, it does not safeguard against earth leakage faults, which can lead to electric shocks or fire risks.
