Rated at 1 A with a C-curve, this MCB is sized for protecting small branch circuits — think control transformers, signal-conditioning supplies, or instrumentation loops — where the inrush from a transformer or capacitive load would nuisance-trip a B-curve. ## Peer comparison The closest functional peer in the 5SQ series is the 5SQ2670-0KA15, which shares the same 4-pole 3P+N configuration, C-curve, 3 kA breaking capacity, 400 V AC rating, and 55 mm depth. The only difference is the current rating: 15 A vs. 1 A. Both occupy 3 width units and switch the neutral. If your panel was specified around the 5SQ2670-0KA15, the 5SQ2670-0KA01 drops into the same DIN-rail slot and busbar arrangement without rewiring — just confirm the branch-circuit load rating. ## Integration notes The 55 mm depth leaves clearance for a standard enclosure door with a 60 mm back-panel depth. Wire termination accepts up to 25 mm² for the line and load side; torque to 2.5 Nm per the terminal marking. Energy limiting class 3 indicates the breaker limits let-through energy to a level that protects downstream components under short-circuit conditions. IP20 rated: suitable for dry indoor panels only.","metaTitle":"SENTRON 5SQ2670-0KA01 4P MCB, 1A, C-Curve, 3kA, 400V AC","metaDescription":"Siemens SENTRON 5SQ2670-0KA01 circuit breaker, 4-pole 3P+N, 1A rated, C-trip characteristic, 3kA breaking capacity per EN 60898/IEC 60947-2, 400V AC, 50Hz.
