It interrupts fault currents up to 10 kA per EN 60898, which means it clears short circuits up to that level without damage to downstream equipment — the standard rating for most industrial distribution boards and sub-panels. The C-curve (tripping between 5 and 10 times rated current) suits it for motor circuits, transformers, and lighting banks where inrush is moderate — not the steep surge of a large drive, but more than a resistive heater load. Pollution degree 3 and overvoltage category III confirm it for fixed installations inside an enclosure, not for outdoor or wet locations. ## Mounting and panel fit Snaps onto standard DIN rail via the quick assembly system, occupying 2 modular width units (36 mm). The 76 mm depth and 70 mm installation depth mean it sits flush with the front of a 100 mm deep enclosure — no extra clearance needed behind the rail. Mounting position is unrestricted, so it works in vertical, horizontal, or inverted panels. Combined terminals top and bottom accept both busbar and cable; touch protection is built in. Rated IP20 with connected conductors — fine for a closed panel, not for washdown zones. The sealable design lets a panel builder lock the toggle position after commissioning. ## Environmental and compliance Designed for railway applications (per the product designation) and mechanical engineering/industry suitability. Halogen-free and silicon-free construction, which matters for clean-room or corrosive-environment installations where outgassing must be minimised.","metaTitle":"Siemens 5SY4225-7CC11 SENTRON MCB, 25A C-Curve 2P 10kA","metaDescription":"Siemens SENTRON 5SY4225-7CC11 miniature circuit breaker, 25 A, C characteristic, 2-pole, 10 kA breaking capacity per EN 60898.
