S501-K4.2产品概述
Type K Double Pole 30 kA - S500 Series
The ABB S500 high performance MCB offers a compact solution to circuit protection. These miniature circuit breakers are current limiting; DIN rail mounted and can offer application specific trip characteristics to provide maximum circuit protection. 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.
