JXD22B300 - 300Amp Circuit Breaker

JXD22B300 - 300Amp Circuit Breaker

The JXD22B300 measures 7.50 inches wide, 11.00 inches long, and 4.00 inches deep, giving you a solid physical reference before you get into the electrical details. This is a 300A, two-pole Type JXD2-A molded case circuit breaker with a non-interchangeable trip unit. The JXD22B300 is built to last, while the decision to replace should remain centered on form, fit, electrical ratings, and compatibility with equipment already in service.

Key Features and Benefits

• 300A, two-pole configuration provides a clear starting point for replacement identification.
• Type JXD2-A helps confirm compatibility with equipment calling for this specific breaker type.
• Uses a non-interchangeable trip unit, an important detail to verify against the existing breaker.
• Load-side lugs are included, making the supplied terminal arrangement clear before installation.
• Well suited to form, fit, and functional replacement in compatible existing and legacy electrical systems.
