JXD62B400 - 400Amp Circuit Breaker

JXD62B400 - 400Amp Circuit Breaker

When you’re trying to match a breaker to equipment that’s already in service, the JXD62B400 gives you several concrete specifications to work from. This is a 400A, two-pole molded-case circuit breaker with a non-interchangeable trip unit and both line-side and load-side lugs. The JXD62B400 is built to last, while the priority for replacement work remains simple: confirm the electrical ratings and connection requirements against the existing system before installation.

Key Features and Benefits

• 400A current rating for equipment requiring this specific amperage.
• Two-pole configuration provides an important compatibility checkpoint when replacing an existing breaker.
• Uses a non-interchangeable trip unit, an important detail to verify against the existing installation.
• Line-side and load-side lugs are included, making the supplied connection arrangement clear.
• Molded case circuit breaker construction for applications calling for this specific breaker configuration.

Material Compliance and Certifications

No specific material-compliance information or certifications were provided for the JXD62B400. UL, CSA, IEC, RoHS, REACH, or other certifications should not be assumed without supporting product documentation. For an installation that requires a particular approval or compliance standard, verify that requirement before use.

Where It Works Best

The JXD62B400 is suited to compatible existing and legacy electrical equipment requiring a 400A, two-pole molded case circuit breaker with a non-interchangeable trip unit and the same interrupting ratings. Because both line- and load-side lugs are included, the terminal arrangement is another useful detail to check when identifying the correct replacement.
