Molded Case Circuit Breakers

Molded case circuit breakers for higher-current AC and DC protection, main distribution, feeder circuits, and equipment protection in marine power systems. Molded-case circuit breakers protect larger feeders and main electrical distribution where available fault current exceeds typical small panel applications. Compare frame size, adjustable trip-unit options, poles, breaking capacity and operating voltage. The catalog includes Schneider NSX devices with thermal-magnetic or electronic trips plus remote-operation accessories; protection coordination should be engineered for the actual vessel system.
