The C-curve means it trips at 5–10× rated current — standard for general-purpose loads like lighting, small transformers, and control circuits where moderate inrush is expected. Breaking capacity is 6 kA per both EN 60898 and IEC 60947-2, so it's suitable for residential and light commercial distribution boards where the prospective fault current stays under that threshold. Rated voltage is 400 V AC phase-to-phase (440 V max), with a maximum DC rating of 60 V. The 4-pole (4P) configuration switches all three phases plus neutral — note that neutral conductor switching is not provided, meaning the neutral pole is a switched pole but the product feature for dedicated neutral switching is absent; treat it as a 4-pole breaker where the neutral pole tracks the phases. Mounting position is any, and the 72 mm width (4 width units) snaps onto standard DIN rail. Conductor range accepts solid or stranded from 0.75 to 25 mm², with a recommended tightening torque of 2.5–3 N·m. Ambient temperature range is -25 to +45 °C, with periodic tolerance to +55 °C at up to 95% humidity. The housing is halogen-free and silicon-free — relevant for environments sensitive to outgassing, such as clean manufacturing or enclosed panels near sensitive electronics. ## Panel integration & compliance Snaps onto standard 35 mm DIN rail. The 76 mm depth (70 mm installation depth) leaves room for wiring behind the panel door. IP20 protection with connected conductors — it's touch-safe when wired but not rated for washdown or outdoor exposure. Overvoltage category III per the evidence, so it's designed for fixed installation downstream of the main distribution board. The sealable feature allows the installer to lock the toggle in the off position with a padlock, meeting lockout/tagout requirements. Compliance documentation typically includes RoHS, REACH, and the relevant IEC/EN standards; the part is designed per EN 60898 and IEC 60947-2 as stated in the breaking capacity ratings.","metaTitle":"Siemens 5SL6401-7BB SENTRON MCB, 1A C-Curve 4P 6kA","metaDescription":"Siemens 5SL6401-7BB SENTRON miniature circuit breaker, 1 A rated, C tripping characteristic, 4-pole, 6 kA breaking capacity per EN 60898/IEC 60947-2.
