Snaps onto DIN rail or takes screw fixing — mounting position any, so you can orient it vertically or horizontally in the enclosure. The 70 mm installation depth (76 mm overall body) and 54 mm width (3 modular units) are the numbers that matter for rail fill and gland-plate clearance. Halogen-free and silicon-free construction. Vibration resistance at 50 m/s² (25–150 Hz) and shock at 150 m/s² half-sine — it holds up in machine-mounted enclosures near rotating equipment.","metaTitle":"Siemens 5SP4280-7 SENTRON MCB, 2P C 80A 400V 10kA","metaDescription":"Siemens 5SP4280-7 SENTRON 5SP miniature circuit breaker, 2-pole, C-curve, 80 A, 400 V AC, 10 kA breaking capacity per EN 60898.
