JXD23B350 - 350Amp Circuit Breaker Description
JXD23B350 - 350Amp Circuit Breaker
The JXD23B350 has a 350A rating, three poles, and a JXD2-A type designation—three useful identifiers when you’re checking a replacement for electrical equipment already in service. The JXD23B350 is built to last, with the focus here remaining on what matters for replacement work: correct form, fit, electrical ratings, trip arrangement, and connections.
Key Features and Benefits
- 350A current rating for equipment requiring this specific amperage.
- Three-pole configuration provides a clear compatibility checkpoint.
- Type JXD2-A identification helps confirm the required breaker type.
- Non-interchangeable trip unit as specified for this breaker.
- Load-side lugs are included, an important connection detail to verify during replacement.
- Well suited to form, fit, and function as a replacement in compatible existing and legacy electrical equipment.

Material Compliance and Certifications
No specific material-compliance information or certifications were included in the supplied specifications for the JXD23B350. UL, CSA, IEC, RoHS, REACH, or other certifications should therefore not be assumed. If a particular approval or compliance requirement applies to the installation, confirm it using the appropriate product documentation before installation.
Where It Works Best
The JXD23B350 is suited to compatible existing and legacy electrical equipment calling for a 350A, three-pole Type JXD2-A molded case circuit breaker with a non-interchangeable trip unit and the stated 65 kA rating at 240VAC. Its included load-side lugs and published case dimensions provide additional details for checking compatibility with an existing installation.
