Siemens FD63B225L 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 225A current rating and a 600V AC voltage rating, housed within a compact FD frame measuring 150mm wide x 250mm high x 170mm deep (5.906" x 9.843" x 6.693") and weighing 10.031 lb. The breaker utilizes a thermal-magnetic trip unit for long-time and instantaneous (LI) protection functions, is certified to UL, CSA, and IEC standards, and operates effectively within a temperature range of -25°C to 70°C (-13°F to 158°F). Its 35kA interrupting rating at 480V AC, feed-thru connection, and compatibility with various panel types including S4, P4, and F2 make it suitable for main and branch circuit protection in industrial control panels and switchboards.
