Because it's an instantaneous design (no intentional delay on the RCD side), it trips fast on earth faults — good for personnel protection in final circuits where you want the fault cleared before it escalates. The 1P+N configuration switches the live pole and monitors the neutral, so it fits single-phase sub-circuits in distribution boards. ## Ratings and derating — what they mean on the panel At 40 °C it's 5.64 A, at 45 °C it's 5.46 A, at 50 °C it's 5.22 A, and at 55 °C it drops to 4.86 A. If your panel runs warm — and most enclosed DIN-rail boards do — size the load against the derated figure, not the 30 °C headline. The operating ambient range is -25 to +45 °C, so above 45 °C you're outside the guaranteed spec window.","metaTitle":"Siemens 5SU9406-1KK06 SENTRON RCD Circuit Breaker, 6 A C-Cur","metaDescription":"Siemens 5SU9406-1KK06 SENTRON RCD-operated circuit breaker, 6 A rated, C tripping characteristic, 1P+N, 6 kA breaking capacity.
