Catalog Description:
Miniature Circuit Breakers MCBs - S280UC - Number of Poles 1 - Tripping characteristic Z

Long Description:

System pro M S280UC is a universal current miniature circuit breaker that provides current limitation. With its high DC voltage rating it is a excellent solution for DC applications in photovoltaic’s, telecommunication, traction and industrial applications. 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,K,Z), configurations (1P,2P,3P,4P), breaking capacities (up to 6 kA at 230/400 V AC) and rated currents (up to 63A). All MCBs of the product range S280UC comply with IEC/EN 60947-2, UL1077 and CSA 22.2 No. 235, allowing the use for commercial and industrial applications in direct current circuits for voltages up to 220 V DC 1 pole and 440 V DC 2, 3 and 4 poles.
