S280 miniature circuit breakers are current limiting. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection. They are available in one module width, different characteristics (B,C), configurations (1P,2P,3P,4P), breaking capacities (up to 6 kA at 230/400 V AC) and rated currents (up to 100A). All MCBs of the product range S280 comply with IEC/EN 60898-1 and IEC/EN 60947-2, allowing the use for residential, commercial and industrial applications.
