The Siemens JXD22B300 is a 2-pole molded case circuit breaker from the Sentron Series, designed for thermal magnetic protection in 1-phase power distribution systems. It is rated for 300A at 240VAC with a 65kA interrupting capacity at 240V, utilizing LI (Long-Time and Instantaneous Trip) functions for overcurrent protection. This bolt-on breaker measures 8.661 x 12.992 x 6.699 inches, weighs 15.099 lb, and features a 400A/JD frame size with lug terminal connections for 500 MCM wire, though it does not include lugs. It complies with RoHS standards and holds UL and IEC certifications, operating within a temperature range of -13°F to 158°F (-25°C to 70°C). Typical applications include use in SB Switchboards Without Lugs and Sentron Panelboards for industrial and commercial power distribution.
