Siemens JXD22B350 Circuit Breaker – Sentron Series – 350A – 2 Pole – 240VAC – Thermal Magnetic – Bolt-On

The Siemens JXD22B350 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 350A and 240VAC, this 2-pole breaker is engineered for single-phase electrical systems requiring high-capacity protection and reliable operation under demanding load conditions.

Featuring a thermal-magnetic trip unit with Long-Time and Instantaneous (LI) protection functions, the JXD22B350 delivers effective protection against sustained overloads and short-circuit faults. Its 65kA interrupting capacity at 240VAC allows it to safely interrupt high fault currents, helping protect electrical equipment and maintain system integrity.

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