Manufacturer: ABB
Mfr. Part No.: 2CDS251001R0487 S201-K20
Type : S201-K20 Miniature Circuit Breaker - 1P - K - 20 A

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 63A). All MCBs of the product range S200 comply with IEC/EN 60898-1, IEC/EN 60947-2, UL1077 allowing the use for residential, commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted on S200 to save 50% space.

Type K Single Pole 6kA - Classic

Type K characteristics have been specifically designed for the protection of motor control circuits and items used within them. It has a very sensitive thermal curve, combined with a magnetic setting of 8 times the normal input current (In), which is high enough to avoid in-rush nuisance tripping, but provides good protection against over current conditions.
