Product details

Siemens 5SJ4103-8HG41 — SENTRON 1-pole D-curve MCB

Breaking capacity is rated at 10 kA per EN 60898 and 15 kA per IEC 60947-2, both at 400 V AC. 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.

Frequently asked questions

What are the key ratings of the 5SJ4103-8HG41?

1-pole, D tripping characteristic, 10 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC. Rated voltage is 400 V AC / 60 V DC. Width is 18 mm (1 modular unit).

Where can I buy the 5SJ4103-8HG41 and get current pricing?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quote — submit an RFQ for a firm price and lead-time estimate.

Will the 5SJ4103-8HG41 fit a panel designed for the 5SY4116-7CV?

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.

What compliance documentation does Siemens provide for the 5SJ4103-8HG41?

The part carries CE marking per the Low Voltage Directive and is designed to EN 60898 and IEC 60947-2. The manufacturer provides a declaration of conformity and, on request, RoHS and REACH compliance statements. UL/CSA listings are not cited in the available spec data for this order code.
