Magnum DS

Air circuit breakers are designed and engineered specifically for use in low voltage assemblies applied at nominal voltages of 380/415, 440, and 500/690 V AC. Nine continuous ratings - 800 amperes through 6300 amperes - are covered by only two breaker sizes. Drawout and fixed mounting available in 3- or 4-pole designs. Controls and indicators are functionally grouped on the front escutcheon of the breakers where they can be easily viewed and accessed through a cutout door.
 

Air circuit breakers are designed to provide circuit protection for low voltage power distribution systems. They safeguard connected apparatus against overloads and/or short circuits. They protect equipment and people.
