This unit switches the neutral pole (1P+N) so that when the breaker trips, both line and neutral are disconnected — a requirement in many national wiring rules for final subcircuits. The 25 mm² solid conductor capacity on the terminals is generous for a 10 A breaker — it accommodates the incoming supply tails common in residential boards without needing a reducer. ## Integration and environmental fit The sealable design allows the distributor to lock the cover after commissioning to prevent tampering. Touch protection is built into the terminals per the product feature listing. ## Coordination and selectivity notes Energy limitation class 3 means this breaker limits the let-through energy (I²t) to a low level, which helps achieve selectivity with upstream devices — a 63 A or 80 A SENTRON SMCB or NH fuse upstream will typically remain closed during a downstream fault on this 10 A unit. This allows remote status monitoring or emergency shutdown integration without replacing the MCB.","metaTitle":"Siemens SENTRON 5SN6510-7CN MCB, 10A C-Curve 1P+N 6kA","metaDescription":"Siemens SENTRON 5SN6510-7CN miniature circuit breaker, 10A, C-characteristic, 1P+N, 6kA breaking capacity per EN 60898, 230V AC.
