It also carries a 60 V DC rating, so it can protect DC control circuits or small battery-backed loads, not just AC branch circuits. Snaps onto standard DIN rail (35 mm) and takes up 3 modular width units (54 mm wide, 70 mm deep, 110 mm tall). ## Construction notes Sealable (can be locked in OFF position with a padlock) for lockout/tagout compliance. Vibration tested to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s), so it holds up on machine-mounted subpanels near motors or conveyors. Rated for mechanical engineering and industry environments per the manufacturer's suitability classification. EMC environment B (immunity not applicable) — this is a passive protective device, not a controller, so no radiated-immunity testing applies.","metaTitle":"Siemens 5SJ4330-7HG41 SENTRON MCB, 3P C-curve, 10 kA","metaDescription":"Siemens 5SJ4330-7HG41 SENTRON 3-pole miniature circuit breaker, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2, 400 V AC, 60 V DC, DIN rail mount, current lifecycle.
