JXD63B350 - 350A Circuit Breaker Description

JXD63B350 - 350A Circuit Breaker

When you're replacing a breaker in equipment that's already in service, 350 amps is only one piece of the puzzle. The JXD63B350 also offers a three-pole configuration, a Type JXD6-A identification, and a non-interchangeable trip unit for comparison with the existing setup. The JXD63B350 is built to last while keeping the job straightforward: confirm the electrical ratings, physical size, trip arrangement, and connection requirements match those of the breaker you're replacing.

Key Features and Benefits

  • 350A, three-pole configuration provides clear electrical identifiers for replacement work.
  • Type JXD6-A makes it easier to confirm compatibility with equipment requiring this specific breaker type.
  • The non-interchangeable trip unit matches installations calling for this trip arrangement.
  • Load-side lugs are included, an important detail to verify when matching connection requirements.
  • A practical choice for form, fit, and functional replacement in compatible existing and legacy equipment.
