The higher IEC figure matters when the part is specified into an industrial distribution board where the prospective fault current exceeds 10 kA; the EN rating governs residential or light-commercial installations. Width is 18 mm (1 modular unit), depth 70 mm, height 110 mm. Mounting position is any orientation — no derating required for horizontal or inverted installation. Combined (box + tunnel) terminals at both top and bottom accept Cu conductors. Vibration resistance tested at 50 m/s² over 25–150 Hz and 60 m/s² at 35 Hz (4 sec duration). This qualifies the breaker for installation on machinery or conveyors with moderate vibration; for high-shock applications (e.g., press lines), verify against the specific vibration profile.","metaTitle":"Siemens 5SJ4103-8HG41 SENTRON MCB, 1P, D-curve, 10kA EN 6089","metaDescription":"Siemens SENTRON 5SJ4103-8HG41 miniature circuit breaker, 1-pole, D tripping characteristic, 10 kA per EN 60898.

Availability and current pricing are confirmed at the time of quote — submit an RFQ for a firm price and lead-time estimate."},{"question":"Will the 5SJ4103-8HG41 fit a panel designed for the 5SY4116-7CV?","answer":"Both are 1-pole, 18 mm wide MCBs on the same DIN-rail footprint, so mechanical fit is identical. The 5SJ4103-8HG41 uses a D curve (10–20× In) versus the 5SY series typically offering B/C curves; verify the tripping characteristic matches the load inrush before substituting. Terminal type and torque spec should also be confirmed against the existing wiring."},{"question":"What compliance documentation does Siemens provide for the 5SJ4103-8HG41?","answer":"The part carries CE marking per the Low Voltage Directive and is designed to EN 60898 and IEC 60947-2.
