The interrupting capacity is rated at 10 kA per EN 60898 and 15 kA per IEC 60947-2, so it clears faults up to that level without cascading upstream; the higher IEC figure applies when the breaker is applied per the industrial standard rather than the residential one. Rated AC voltage is 400 V, DC voltage 60 V, with an insulation voltage (Ui) of 440 V AC. Pollution degree 3 and overvoltage category 3 mean it's rated for the conductive environment inside a typical industrial enclosure — not a clean-room panel, but a standard IP54 cabinet with some dust and condensation. The breaker mounts on standard DIN rail (35 mm) in any position, and occupies 2 modular width units (36 mm total width). ## Deployment context and environmental limits This MCB is suited for mechanical engineering and industry applications per the manufacturer's designation. The ambient temperature range spans -40 °C to 75 °C, with a maximum 95% humidity — wide enough for unheated plant floors or outdoor cabinets in temperate climates, though the upper limit of 75 °C means it can sit near heat sources inside a panel without derating concerns. Vibration resistance is specified at 50 m/s² over 25 to 150 Hz and 60 m/s² at 35 Hz (4-second dwell), which covers the typical vibration profile of a motor control center or a panel mounted on a machine frame. The protection class is IP20 with connected conductors, and IP40 in the handle range — standard for a DIN-rail component inside an enclosure. EMC environment B means immunity to interference is not applicable — this is a passive protective device, not a sensitive electronic load.","metaTitle":"Siemens 5SJ4232-8HG41 SENTRON MCB, 2-Pole D-Curve, 10kA","metaDescription":"Siemens 5SJ4232-8HG41 SENTRON miniature circuit breaker, 2-pole, D tripping characteristic, 10 kA per EN 60898, 15 kA per IEC 60947-2.
