Breaking capacity sits at 6 kA per EN 60898 and 15 kA per IEC 60947-2 — the higher figure applies when the breaker is installed per the industrial standard, giving you a 15 kA SCCR at 400 V for fault interruption without upstream cascade. Current derates with ambient temperature: 25 A at 35 °C, 24 A at 40 °C, 23.5 A at 45 °C, 22.98 A at 50 °C, 22.45 A at 55 °C. If your panel runs hot, size the load to the derated value at the actual ambient — the 25 A nameplate is only good at 35 °C. Installation depth is 70 mm; total depth including the front arc is 76 mm. Mounting position is any — vertical, horizontal, upside down in a tight enclosure — no derating needed for orientation. Sealable with a lead seal or adhesive label for tamper-proofing in metering or critical circuits.","metaTitle":"Siemens 5SY6625-6 SENTRON MCB, 4P B-Curve 25A, 6/15 kA","metaDescription":"Siemens 5SY6625-6 SENTRON miniature circuit breaker, 4-pole (3P+N), B-curve, 25 A rated at 35 °C, 400 V AC.

The difference is the trip curve — 5SY6625-6 is B-curve (3–5x In), while 5SY4140-7 is C-curve (5–10x In). If the panel was coordinated for C-curve selectivity, swapping to B-curve will trip faster on inrush and may lose discrimination with the upstream breaker."},{"question":"How do I get current pricing and availability for 5SY6625-6?","answer":"Submit an RFQ through this listing.
