Mounting position is unrestricted — install it horizontally or vertically as the cabinet layout demands. Terminals are combined (screw + clamp) top and bottom, accepting Cu conductors at a tightening torque of 3.5 Nm. No tunnel terminals — the combined design suits both solid and stranded wire without ferrules. IP20 with connected conductors; ## Breaking capacity and trip curve Rated at 400 V AC and 60 V DC maximum. The DC rating is limited to 60 V, so for 110 V DC or 220 V DC battery banks you need a different breaker. Insulation voltage (Ui) is 440 V AC — the breaker is insulated for 440 V line-to-line but its switching duty is capped at 400 V AC. Supply frequency is 50 Hz. No 60 Hz rating is listed — if your installation runs on 60 Hz, confirm thermal performance with the manufacturer. Ambient humidity tolerance is 95% max, non-condensing. ## Environmental and mechanical specs Vibration resistance is rated at 50 m/s² over 25–150 Hz and 60 m/s² at 35 Hz (4 sec) — sufficient for machine-mounted panels near rotating equipment. The breaker is suitable for mechanical engineering and industry applications per the manufacturer's own classification. EMC environment B (immunity not applicable) means it is intended for industrial premises where conducted and radiated interference levels are controlled by the installation.","metaTitle":"Siemens 5SJ4103-7HG41 SENTRON MCB, 1-pole C-curve, 10 kA","metaDescription":"Siemens 5SJ4103-7HG41 SENTRON miniature circuit breaker, 1-pole, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2.

The 5SJ4103-7HG41 is a C-curve breaker; the 5SY4116-7CV is also a C-curve. The main difference is breaking capacity — the 5SJ4 series carries 15 kA per IEC 60947-2 versus the 5SY series rating.
