Four poles (4P) switch all four conductors — three phases plus neutral — so it's sized for a three-phase supply where the neutral needs overcurrent protection. ## Where it goes — deployment context This MCB is designed for residential buildings and infrastructure — think distribution boards in apartment blocks, small commercial premises, or utility sub-mains.","metaTitle":"Siemens 5SL6425-6RC SENTRON MCB, 25A 4P B-Char 7.5kA","metaDescription":"Siemens 5SL6425-6RC SENTRON miniature circuit breaker, 25 A, 4-pole, B characteristic, 7.5 kA breaking capacity per EN 60898.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm delivery commitment."},{"question":"What is the breaking capacity of 5SL6425-6RC?","answer":"The breaking capacity is 7.5 kA per EN 60898 at 415 V AC. That's the maximum fault current the MCB can safely interrupt under standard test conditions."},{"question":"What are the physical dimensions of 5SL6425-6RC?","answer":"The MCB measures 72 mm wide (4 width units), 90 mm high, and 76 mm deep (70 mm installation depth). Fits standard DIN-rail enclosures."},{"question":"Will 5SL6425-6RC drop into a panel specified around 5SL4120-7CC?","answer":"Both are SENTRON 5SL series MCBs with the same 4-pole DIN-rail footprint, so physical fit is identical. The difference is rating: 5SL6425-6RC is 25 A B-characteristic 7.5 kA; 5SL4120-7CC is a different rating and characteristic. Verify the branch circuit's ampacity and fault level before swapping — the mechanical swap is straightforward, but the electrical ratings must match the design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6425-6RC","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/5SL6425-6RC when reusing this data.
