Siemens FD63B150 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 150A continuous current rating and a 600V AC voltage rating, housed within a compact FD frame measuring 150mm wide by 250mm high by 170mm deep (5.906" x 9.843" x 6.693") and weighing 9.017 lb. This thermal-magnetic breaker, offering long-time and instantaneous (LI) protection with a 35kA interrupting capacity at 480V AC, is UL, CSA, and IEC certified for operation from -25°C to 70°C (-13°F to 158°F). Its three-pole, bolt-on configuration makes it suitable for panelboards, switchboards, and industrial control panels, though field-installable lugs are required separately for conductor termination.
