RCBO 45A 30mA Single Pole + Ns B Curve

Residual current circuit breaker with overcurrent protection (RCBO) are designed to ensure the safe operation of electrical circuits, triggering disconnection whenever an imbalance is detected. These use thermal magnetic trip unit technology. B curve breakers trip between 3-5 times rated current in a short circuit situation. B curve MCBs should be applied where loads are resistive and do not have in-rush current. The ideal application is lighting or electronic circuits.
