Two poles give you simultaneous disconnection of both line conductors — needed for a 2-phase or split-phase circuit, or as a double-pole main on a single-phase subpanel. The 400 V AC rating covers standard 230/400 V three-phase networks; the 72 V DC maximum means it can also serve low-voltage DC loads like control circuits or small battery banks, though the DC breaking capacity is not separately listed. ## Panel space and mounting Width is 36 mm — that is 2 modular units (MW) on a standard DIN rail, so it occupies two 18 mm slots in a distribution board. Depth of 76 mm (70 mm installation depth) means it fits flush in most domestic enclosures without the cover hitting the breaker. Mount in any position; the -40 °C to +75 °C ambient range covers unheated plant rooms and outdoor cabinets in cold climates. Fine inside a clean panel; do not mount it exposed to washdown or outdoor spray without an IP-rated enclosure around it.","metaTitle":"Siemens 5SJ6225-7FC SENTRON MCB, 2-pole C-curve 25A, 6kA","metaDescription":"Siemens SENTRON 5SJ6225-7FC miniature circuit breaker, 2-pole, C-curve, 25A, 6kA breaking capacity per EN 60898.

That is the standard rating for residential and light-commercial distribution boards."},{"question":"Will 5SJ6225-7FC drop into a panel specified for 5SL4363-7?","answer":"No — 5SL4363-7 is a 3-pole, 54 mm wide breaker. The 5SJ6225-7FC is 2-pole at 36 mm wide. The DIN rail footprint matches, but the pole count and slot width differ; you would need to re-plan the busbar and circuit assignment."},{"question":"What compliance documentation does Siemens provide for 5SJ6225-7FC?","answer":"The part carries EN 60898 certification for breaking capacity. It is halogen-free and silicon-free. Standard Siemens declarations (CE, UKCA) apply; specific RoHS/REACH declarations are available from the manufacturer on request."},{"question":"Where can I buy 5SJ6225-7FC and how is it quoted?","answer":"Sourced through independent distribution channels.
