Cutler-Hammer KD2400 U Molded Case Circuit Breaker

Cutler-Hammer KD2400 U molded case circuit breaker is a two-pole protection device rated for 400 A at 600 V. This KD2400 U unit from Cutler-Hammer belongs to a molded-case family designed to provide interrupting protection in electrical distribution panels and control gear. The 2P configuration indicates two current-carrying poles, enabling protection for paired conductors within a single package. With a 400 A rating, the breaker is intended to carry up to that continuous current under normal operation and to trip to prevent damage when fault current exceeds its designed threshold; the 600 V rating defines the maximum voltage of the circuits it is designed to protect. As a molded case breaker, it offers a sturdy enclosure with integrated overcurrent protection suitable for commercial and industrial installations where space and reliability matter. The Cutler-Hammer brand is a long-standing name in electrical protection equipment, and the KD2400 U designation identifies its specific frame within the KD series.
