Siemens FD63B175 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 175A continuous 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 8.444 lb. This thermal-magnetic breaker, offering Long-time and Instantaneous (LI) protection functions with a 35kA interrupting capacity at 480V AC, is UL, CSA, and IEC certified for safe operation in temperatures from -25°C to 70°C (-13°F to 158°F). Its three-pole, bolt-on configuration makes it suitable for installation in various panelboards including S4, P4, S5, P5, and F2 types, commonly used in manufacturing facilities, commercial buildings, and other critical infrastructure (note: lugs are not included and must be sourced separately).
