Siemens MD63F800 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a 600V AC voltage rating and an 800A continuous current rating, housed within a robust 48.5 lb MD frame constructed for durability. This thermal magnetic breaker offers LI (Long-time and Instantaneous) protection functions, achieves an interrupting capacity of 50kA at 480V, and complies with UL and IEC standards for safety and performance. Its feed-thru connection design is typically applied in panelboards, switchboards, and industrial control panels where a frame-only component is specified, noting the trip unit and lugs are supplied separately.
