JXD22B350L - 350Amp Circuit Breaker

JXD22B350L - 350Amp Circuit Breaker

When you’re tracking down a JXD22B350L for equipment already in service, there are several useful identifiers right on the spec sheet. It’s a 350A, two-pole molded case circuit breaker with the JXD2-A type designation and a non-interchangeable trip unit. The JXD22B350L is built to last, but choosing the right replacement still comes down to compatibility. Compare the type, amperage, poles, trip arrangement, lug setup, interrupting ratings, and dimensions to those of the breaker currently installed.

Key Features and Benefits

• 350A rating with two poles for applications requiring this exact electrical configuration.
• JXD2-A type designation provides an important reference when matching an existing breaker.
• Uses a non-interchangeable trip unit.
• Line-side and load-side lugs are included, giving you a clearly identified connection arrangement.
• A practical choice for form, fit, and functional replacement where the existing equipment calls for these specifications.

Material Compliance and Certifications

No specific material compliance or certification information was included in the supplied specifications for the JXD22B350L. UL, CSA, IEC, RoHS, REACH, and other certifications should therefore not be assumed. Where a particular approval is required, verify the applicable documentation before installation.

Where It Works Best

The JXD22B350L is intended for compatible existing and legacy equipment that requires a 350A, two-pole JXD2-A molded case circuit breaker with a non-interchangeable trip unit and lugs on both the line and load sides.

For replacement work, don’t stop at the amp rating. Check the JXD2-A designation, two-pole arrangement, trip-unit type, AC and DC interrupting ratings, lug configuration, and physical dimensions against the equipment already in place. Those details provide a much better basis for confirming the correct form, fit, and function.
