Product details

Rated 400 V AC and 60 V DC, it carries a breaking capacity of 10 kA per EN 60898 and 15 kA per IEC 60947-2 — the higher IEC figure matters when the breaker is used as a standalone industrial device rather than a domestic distribution board component. The D curve (10–20× In) means it tolerates short-duration surges without nuisance tripping, which is exactly what you need feeding a contactor coil bank or a small drive.

Duty and environment

IP20 with connected conductors, IP40 in the handle area — the handle zone is splash-resistant enough for basic panel protection, but the terminals themselves aren't sealed for washdown. Vibration resistance is specified at 50 m/s² over 25–150 Hz and 60 m/s² at 35 Hz, so it holds up on a machine frame or a conveyor drive section.

Frequently asked questions

Where can I buy 5SJ4116-8HG42 and how do I get a price?

This part is sourced and quoted to order through independent distribution. Submit an RFQ; availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 5SJ4116-8HG42?

The Siemens 5SY4116-7CV shares the same D curve, 1-pole format, and DIN-rail footprint, but its breaking capacity and voltage ratings should be verified against your specific application — the 5SJ4 series carries higher IEC 60947-2 interrupting ratings (15 kA vs the 5SY's typical 10 kA). Panel drop-in is mechanically identical, but the 5SY may not meet the same SCCR requirements.

What is 5SJ4116-8HG42's listed depth?

Depth is 70 mm, matching the standard 5SJ4 envelope. Installation depth is also 70 mm — no extra clearance needed behind the DIN rail.

What compliance documentation does this brand provide for 5SJ4116-8HG42?

The SENTRON 5SJ4 series is designed to EN 60898 and IEC 60947-2. RoHS and REACH compliance is standard for Siemens industrial control gear. Specific declarations are available on request with the RFQ.
