Автомат таслуур S294-C100

S290 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 different characteristics (B,C,K), configurations (1P,2P,3P,4P), breaking capacities (up to 20 kA at 230/400 V AC) and rated currents (up to 125A). All MCBs of the product range S290 comply with IEC/EN 60898-1, IEC/EN 60947-2 and UL1077, allowing the use for residential, commercial and industrial applications.
