The ABB DS201C6AC30 is a residual current circuit breaker with integrated overcurrent protection — an RCBO in one DIN-rail module.
Deployment context
As a DIN-rail-mount RCBO, the DS201C6AC30 is used in distribution boards and sub-panels where both earth-leakage and overcurrent protection are required in a single device, saving rail space versus a separate RCCB plus MCB pair.
