The Siemens JXD22B250 is a 2-pole, 250A molded case circuit breaker from the Sentron Series, designed for thermal-magnetic protection in industrial power distribution systems. It operates at 240V with a 65kA interrupting capacity and features LI (Long-Time and Instantaneous Trip) functions for precise overcurrent protection. This bolt-on breaker measures 8.661 x 12.992 x 6.697 inches, weighs 15.201 lb, and accepts up to 500 MCM wire via lug terminals, though lugs are not included. It is UL and IEC certified, RoHS compliant, and rated for operation from -13°F to 158°F (-25°C to 70°C). The JXD22B250 is intended for use in SB Switchboards without lugs and Sentron Panelboards, supporting 1-phase systems with a 400A/JD frame size.
