JXD23B400L - 400Amp Circuit Breaker

JXD23B400L - 400Amp Circuit Breaker

Need to match a JXD23B400L to equipment that’s already in service? A few details make this breaker easy to identify. It’s a 400A, three-pole molded case circuit breaker with the JXD2-A type designation and a non-interchangeable trip unit. The JXD23B400L is built to last, but the real key to selecting your replacement is getting the details right. Check the amperage, pole count, JXD2-A type, trip arrangement, interrupting rating, dimensions, and lug setup against the breaker and equipment already in place.

Key Features and Benefits

• 400A, three-pole rating for equipment requiring this specific electrical configuration.
• Type JXD2-A provides an important identifier when matching an existing breaker.
• Uses a non-interchangeable trip unit as specified for this model.
• Line-side and load-side lugs are included, making the supplied connection arrangement clear.
• A practical choice for form, fit, and functional replacement where the existing equipment calls for the same specifications.

Material Compliance and Certifications

No specific material-compliance information or certifications were included in the supplied specifications for the JXD23B400L. UL, CSA, IEC, RoHS, REACH, or other approvals should therefore not be assumed. If your installation requires a particular certification or compliance standard, confirm that requirement against the applicable product documentation.

Where It Works Best

The JXD23B400L is best suited to compatible existing and legacy electrical equipment that calls for a 400A, three-pole Type JXD2-A molded case circuit breaker with a non-interchangeable trip unit. Its included line- and load-side lugs are another useful detail when comparing it with the breaker being replaced.
