Siemens MXD63B500 is a 3-pole molded case circuit breaker from the Sentron Series designed for thermal magnetic overcurrent protection in industrial power distribution systems. Rated for 600V AC and 500A with a 50kA interrupting capacity at 480V, this MD Frame breaker provides LI (Long-Time and Instantaneous) protection functions for reliable fault isolation. The unit weighs 65 lb and features a bolt-on connection style for secure panel mounting, though it does not include lugs. It complies with industry standards for 3-phase applications and is constructed for robust performance in demanding electrical environments. Typical industrial applications include main switchboard protection, feeder circuit protection, and large motor branch circuits in manufacturing facilities, data centers, and commercial buildings.
