Siemens JXD22B250 Circuit Breaker – Sentron Series – 250A – 2 Pole – 240VAC – Thermal Magnetic – Bolt-On

The Siemens JXD22B250 is a Sentron Series molded case circuit breaker designed to provide dependable overload and short-circuit protection for commercial, industrial, and power distribution applications. Rated at 250A and 240VAC, this 2-pole breaker is engineered for single-phase electrical systems requiring reliable protection and high-performance fault interruption.

Featuring a thermal-magnetic trip unit with Long-Time and Instantaneous (LI) protection functions, the JXD22B250 delivers effective protection against overload conditions and short-circuit faults. With a 65kA interrupting capacity at 240VAC, it is capable of safely clearing high fault currents, helping protect electrical equipment and maintain system reliability.

Built on the JD frame platform and rated for operation in 40°C ambient conditions, this breaker utilizes a secure bolt-on mounting design and comes complete with a factory-installed non-interchangeable trip unit. Lugs are not included, allowing flexibility in selecting appropriate terminal connections for specific installation requirements.
