Rated 30 A at both 30 °C and 40 °C ambient, the 5SJ4130-6HG40 holds full current without derating up to 40 °C. Above that, it steps down: 29.1 A at 45 °C, 28.2 A at 50 °C, 27.2 A at 55 °C, and 26.4 A at 60 °C. For a panel running warm — say, 50 °C inside the enclosure — the breaker still handles 28.2 A continuous, which is a 6% reduction from the nameplate. That derating curve is the one to use when sizing for a crowded cabinet. The DC rating is 60 V maximum, so this single-pole MCB can switch a 60 VDC control circuit or small DC load, but not a 125 VDC battery bank. Vibration resistance is specified at 50 m/s² over 25 to 150 Hz and 60 m/s² at 35 Hz for 4 seconds. That's a machine-tool or conveyor-adjacent environment where moderate vibration is present; the breaker won't nuisance-trip from panel vibration alone. IP20 with connected conductors, IP40 in the handle area. That's standard for a panel-mounted MCB — not washdown-rated, but fine inside a closed enclosure.","metaTitle":"Siemens SENTRON 5SJ4130-6HG40 MCB, 1P, B-30A, 18mm","metaDescription":"Siemens SENTRON 5SJ4130-6HG40 miniature circuit breaker, 1-pole, B-curve, 30 A at 40 °C, 18 mm wide, DIN-rail mount, IP20.

This is the space required behind the panel face for the breaker body."},{"question":"What is 5SJ4130-6HG40's listed width?","answer":"The width is 18 mm, which is one modular unit (1 MW) on standard DIN rail.

However, the 5SJ4 and 5SL series may have different interrupting ratings, so coordination studies or panel labels should be checked before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SJ4130-6HG40","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SJ4130-6HG40 when reusing this data.
