Siemens JXD62B250 Circuit Breaker – Sentron Series – 250A – 2 Pole – 600VAC – Thermal Magnetic – Feed-Thru

The Siemens JXD62B250 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 600VAC, this 2-pole breaker is engineered for single-phase electrical systems requiring reliable protection and high-performance operation in demanding environments.

Equipped with a thermal-magnetic trip unit featuring Long-Time and Instantaneous (LI) protection functions, the JXD62B250 delivers effective protection against sustained overload conditions and high-level fault currents. The breaker offers multiple interrupting ratings, including 100kA at 240VAC, 35kA at 480VAC, and 25kA at 600VAC, providing dependable fault-clearing performance across a variety of voltage applications.

Built on the Siemens JXD frame platform and calibrated for operation in 40°C ambient environments, this breaker features a feed-thru connection design and comes complete with a factory-installed non-interchangeable trip unit as well as line- and load-side lug terminals for simplified installation and secure connections.
