Siemens JXD22B400 Circuit Breaker – Sentron Series – 400A – 2 Pole – 240VAC – Thermal Magnetic – Bolt-On

The Siemens JXD22B400 is a Sentron Series molded case circuit breaker engineered to provide reliable overload and short-circuit protection for commercial, industrial, and power distribution applications. Rated at 400A and 240VAC, this 2-pole breaker is designed for single-phase electrical systems that require high-capacity circuit protection and dependable performance in demanding operating environments.

Equipped with a thermal-magnetic trip unit featuring Long-Time and Instantaneous (LI) protection functions, the JXD22B400 offers effective protection against sustained overload conditions and high-level fault currents. With a 65kA interrupting capacity at 240VAC, it can safely interrupt substantial short-circuit currents, helping protect electrical equipment and maintain system reliability.

Built on the Siemens JD frame platform and designed for operation in 40°C ambient environments, this breaker utilizes a secure bolt-on mounting configuration and is supplied with a factory-installed non-interchangeable trip unit. Lugs are not included, providing flexibility in selecting terminal connections that best suit the application.
