The 4 A rating at 30 °C is the continuous current it carries without tripping; derate for higher ambient temperatures (the spec table shows ratings at 40, 45, 50, 55 °C on the single-pole sibling, and this 4-pole unit follows a similar thermal curve). At 4 MW (72 mm wide), it takes up four 18 mm slots — plan your enclosure fill accordingly. Mounting position is unrestricted, which helps in tight enclosures where vertical or horizontal rail orientation is forced.","metaTitle":"Siemens 5SL6404-7RC SENTRON MCB, 4A 4-Pole C-Curve 7.5kA","metaDescription":"Siemens 5SL6404-7RC SENTRON miniature circuit breaker, 4A, 4-pole, C characteristic, 7.5 kA breaking capacity per EN 60898.

The footprint is four times wider, so it will not fit the same DIN-rail position without re-spacing the entire row. The wiring also differs: the 4-pole needs, L2, L3, and neutral connections; the single-pole only needs one phase. A panel built around the single-pole unit would require significant rework to accommodate this 4-pole breaker."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6404-7RC","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/5SL6404-7RC when reusing this data.
