Industrial CDK2400 Molded Case Circuit Breaker

Challenger CDK2400 molded case circuit breaker is a rugged, two-pole protection device rated for 400 A at 240 V, designed for industrial panels, motor-control centers, and other high-demand distribution applications. This bolt-on, molded-case breaker employs thermal-magnetic trip technology with long-time and instantaneous protection, delivering 65 kAIC at 240 V for robust short-circuit handling. UL-listed and part of the CDK Series, it provides reliable overcurrent protection in demanding environments where space-conscious, high-current protection is required. Typical installations include motor feeders and panelboards in industrial facilities, where compact form factors and bolted connections simplify mounting and maintenance. Key specifications include 2-pole, 1-phase operation; 400 A nominal rating; 240 V nominal; and 65 kAIC interrupting capacity at 240 V, with bolt-on termination for straightforward integration into compatible bus and panel infrastructures.
