No last-time-buy or phase-out notice applies — specify it into your BOM with confidence. ## DIN Rail & Panel Integration Overall dimensions: 54 mm wide × 110 mm high × 70 mm deep. Any mounting position works; installation depth matches the overall depth. Combined terminals top and bottom ease wiring in tight cabinets. Terminal tightening torque specified at 3.5 N·m for copper conductors at 60/75 °C. IP20 with connected conductors, IP40 in the handle area — no sealed enclosure needed for basic dust protection. Sealable design (lockable handle) supports tamper-proof installations. Suitable for environment B (immunity to interference not applicable). Same part, different passport — if you see this at a discount from another region, the internal construction is identical. Our cross-border sourcing verifies provenance to match your local compliance requirements.","metaTitle":"Siemens 5SJ4318-7HG41 SENTRON MCB, 3P, C-Curve, 10 kA","metaDescription":"Siemens 5SJ4318-7HG41 SENTRON miniature circuit breaker, 3 poles, C curve, 10 kA per EN 60898, 15 kA per IEC 60947-2.
