Depth 70 mm. Rated current holds at 32 A up to 40 °C ambient; above that it derates to 31 A at 45 °C, 30.1 A at 50 °C, 29 A at 55 °C, and 28.16 A at 60 °C. ## Environmental and compliance details Halogen-free and silicon-free construction, rated for pollution degree 3 (industrial environments with conductive or dry non-conductive pollution). Sealable with a lead or tag for lockout/tagout programs. Vibration resistance tested to 50 m/s² over 25–150 Hz and 60 m/s² at 35 Hz for 4 seconds — tough enough for machine-mounted subpanels on a conveyor line. IP20 with connected conductors; IP40 in the handle range. That's standard for a panel-mounted MCB — fine inside a closed enclosure, but not for washdown zones without a cover. ## DC rating note Maximum DC voltage rating is 60 V. If you're using this in a DC control circuit (e.g., 24 VDC or 48 VDC bus), it's rated for that — but the breaking capacity figure (10 kA) is per EN 60898, which is an AC standard. For DC fault levels, verify the DC breaking capacity from the manufacturer's DC derating data.","metaTitle":"Siemens 5SJ4132-8HG40 SENTRON MCB, 1P, D Curve, 32 A, 10 kA","metaDescription":"Siemens SENTRON 5SJ4132-8HG40 miniature circuit breaker, 1-pole, D tripping characteristic, 32 A rated current, 10 kA breaking capacity per EN 60898.
