JXD22B400 - 400Amp Circuit Breaker

JXD22B400 - 400Amp Circuit Breaker

If the breaker you’re replacing calls for 400 amps, two poles, and Type JXD2-A, the JXD22B400 gives you several other details to confirm before installation. This molded case circuit breaker uses a non-interchangeable trip unit and includes load-side lugs. The JXD22B400 is built to last, while the replacement decision should stay focused on getting the correct form, fit, and function. Check the type designation, amperage, pole count, trip arrangement, lug setup, interrupting ratings, and dimensions against the breaker and equipment already in service.

Key Features and Benefits

• 400A, two-pole configuration provides clear electrical identifiers for replacement matching.
• Type JXD2-A helps confirm compatibility with equipment requiring this specific breaker type.
• Uses a non-interchangeable trip unit, an important detail to verify against the existing breaker.
• Load-side lugs are included with this configuration.
• Well suited to form, fit, and functional replacement in compatible existing and legacy electrical equipment.
