JXD23B400 - 400 Amp Circuit Breaker Description
JXD23B400 - 400 Amp Circuit Breaker
When you’re sourcing a JXD23B400, the part number is only the beginning. The details that really help confirm the fit are 400 amps, three poles, Type JXD2-A, and the breaker’s non-interchangeable trip unit. JXD23B400 is built to last, but the right replacement still comes down to compatibility. Check the type, amperage, pole count, trip arrangement, interrupting rating, physical dimensions, and connections before installation.
Key Features and Benefits
- 400A, three-pole configuration provides two of the main identifiers needed when checking replacement compatibility.
- Type JXD2-A provides another specific reference for comparison with the breaker already installed.
- The non-interchangeable trip unit matches installations calling for this trip-unit arrangement.
- Load-side lugs are included, making the supplied connection setup easy to identify.
- A practical choice for form, fit, and functional replacement in compatible existing and legacy systems.

Material Compliance and Certifications
No specific material-compliance information or certifications were included in the supplied specifications for the JXD23B400.

Where It Works Best
The JXD23B400 is a natural fit for replacement work in compatible existing and legacy electrical equipment that calls for a 400A, three-pole Type JXD2-A molded case circuit breaker. Its non-interchangeable trip unit, load-side lugs, published dimensions, and 65 kA at 240 VAC rating give you several concrete details to compare with the breaker being replaced.
