Type K Triple Pole 10 kA - System Pro M Compact
The ABB S200 Series of MCB offer a compact solution for protection requirements. These miniature circuit breakers are current limiting; DIN rail mounted and can offer a good equivalent to fused systems. 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, which is high enough to avoid in-rush nuisance tripping, but provides good protection against over current conditions.
