Description
S201-B6 Miniature Circuit Breaker
System pro M compact S200 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,D,K,Z), configurations (1P,1P+N,2P,3P,3P+N,4P), breaking capacities (up to 6 kA at 230/400 V AC) and rated currents (up to 63 A). All MCBs of the product range S200 comply with IEC/EN 60898-1, IEC/EN 60947-2, UL1077 allowing use for residential, commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted on S200 to save 50% space.
Electrical Ratings and Performance: Rated ultimate short-circuit breaking capacity up to 20 kA at 133 V AC, 10 kA at 230 V AC and 400 V; rated service short-circuit breaking capacity up to 15 kA. Rated insulation voltage 440 V, rated current 6 A, tripping characteristic type B, operating frequency 50/60 Hz.
Mechanical and Electrical Endurance: 20,000 AC cycles electrical endurance and 20,000 mechanical cycles.
