The B-curve (3–5 × In) trips fast on short-circuit but tolerates the inrush of resistive and modest motor loads; it's the standard choice for general-purpose branch circuits in residential buildings and infrastructure (the listed suitability). ## Four poles, 72 mm wide — fits a standard DIN-rail panel Four poles (4P) in a 72 mm-wide housing (4 width units at 18 mm each). Mounts on a DIN rail in any orientation. Installation depth is 70 mm; total depth with terminals is 76 mm. Tightening torque is 2.5 to 3 N·m. The housing is sealable and halogen-free, silicone-free. IP20 with conductors connected, overvoltage category III. Ambient temperature range -25 to +55 °C, storage -40 to +75 °C.","metaTitle":"Siemens 5SL4404-6 SENTRON MCB, 4 A, B-Curve, 10 kA, 4-Pole","metaDescription":"Siemens 5SL4404-6 SENTRON miniature circuit breaker, 4 A rated, B tripping characteristic, 10 kA breaking capacity (EN 60898 / IEC 60947-2), 4-pole, 400 V AC.
