Rated 10 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC; that covers most industrial panel fault levels up to that threshold. Single-module width (18 mm) snaps onto standard DIN rail, any mounting position. Combined terminals top and bottom (no tunnel terminals), so you can fork or pin the conductor. Terminal torque spec: 3.5 Nm for Cu conductors rated 60/75 °C. Sealable, halogen-free, silicon-free — relevant for food, pharma, or clean-room panels where outgassing or tamper-proofing matters. IP20 with conductors connected; IP40 in the handle area. Vibration-rated: 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 sec). The 5SJ4 series is Siemens' standard MCB line for industrial and commercial distribution; this variant (C-curve, 1-pole, 10 kA) is a common BOM item.","metaTitle":"Siemens 5SJ4114-7HG40 SENTRON MCB, 1P C-Curve, 10 kA","metaDescription":"Siemens 5SJ4114-7HG40 SENTRON miniature circuit breaker, 1-pole, C characteristic, 10 kA per EN 60898. 18 mm width, DIN rail mount.
