It's rated for 400 VAC and 60 VDC, so it'll handle standard three-phase panel feeds on the AC side and control-voltage DC circuits as well. The 70 mm installation depth includes the terminal clearance; you won't need extra bending room behind the DIN rail for this one. IP20 with conductors connected, IP40 in the handle range — that's standard for panel-mounted breakers. It's not a washdown part, but it's fine inside a clean enclosure. The combined terminal design (top and bottom) accepts copper conductors with a tightening torque of 3.5 Nm, and it's rated for 60/75 °C wire. ## Environmental and compliance specs Temperature range is wide: -40 °C to +75 °C ambient, so it'll survive a cold warehouse startup or a hot summer afternoon in a non-climate-controlled panel. Vibration resistance is listed at 50 m/s² from 25 to 150 Hz and 60 m/s² at 35 Hz — that's enough for mounting on a machine base or near a conveyor drive without nuisance tripping. Halogen-free and silicon-free construction, sealable option — that matters if you're putting this in a food plant or a clean room where outgassing or contamination is a concern. It's also suitable for environment B regarding EMC, which covers most industrial locations.","metaTitle":"Siemens 5SJ4110-7HG40 SENTRON MCB, C-Curve 1P, 10kA/15kA","metaDescription":"Siemens 5SJ4110-7HG40 SENTRON miniature circuit breaker, 1-pole C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2.
