JXD22B400L - 400Amp Circuit Breaker

JXD22B400L - 400Amp Circuit Breaker

With the JXD22B400L, you have several concrete details to check against the breaker already in service. This is a 400A, two-pole molded-case circuit breaker identified as Type JXD2-A with a non-interchangeable trip unit. Both line-side and load-side lugs are included, so the connection arrangement is clearly defined. The JXD22B400L is built to last, but choosing the right replacement is really about the details: type, amperage, pole count, trip arrangement, connections, ratings, and physical size all need to agree with the equipment already in place.

Key Features and Benefits

• 400A, two-pole rating for equipment requiring this exact electrical configuration.
• Identified as Type JXD2-A for easier comparison with an existing breaker.
• Uses a non-interchangeable trip unit.
• Comes with line-side and load-side lugs included.
• Well suited to form, fit, and functional replacement in compatible existing and legacy equipment.

Material Compliance and Certifications

No specific material-compliance or certification information was provided for the JXD22B400L. UL, CSA, IEC, RoHS, REACH, and other certifications should not be assumed from the available specifications. If a particular standard or listing is required for the installation, confirm it separately before use.

Where It Works Best

The JXD22B400L is a practical choice for maintaining existing or legacy electrical equipment that requires a 400A, two-pole Type JXD2-A molded case circuit breaker with a non-interchangeable trip unit. The included line- and load-side lugs are another useful point to compare with the breaker being replaced.

Before installation, check the complete specification set rather than relying on amperage alone. Confirm the JXD2-A type, two-pole arrangement, 400A rating, interrupting ratings, trip-unit design, lug setup, and physical dimensions against the existing equipment.
