The 1+N-pole configuration switches the phase and provides a switched neutral, common in single-phase final circuits where isolating both conductors is required for maintenance safety. The 1+N-pole width occupies two modular spaces (36 mm). Terminal capacity accepts up to 25 mm² conductor for the incoming supply and outgoing load — sized for the 40 A rating without needing a ferrule or bootlace. The C-curve characteristic means coordination with upstream and downstream devices should follow the manufacturer's selectivity tables; at 40 A and 10 kA, this breaker coordinates well with a 63 A or 80 A upstream SENTRON NH fuse or a higher-rated 5SL series MCB for full discrimination up to the fault level.","metaTitle":"Siemens 5SL4540-7CC Miniature Circuit Breaker, C-Curve, 40 A","metaDescription":"Siemens 5SL4540-7CC miniature circuit breaker, 1+N-pole, C-curve, 40 A, 230 V, 10 kA breaking capacity.
