JXD22B300L - 300Amp Circuit Breaker

JXD22B300L - 300Amp Circuit Breaker

At 300 amps, the JXD22B300L has a fairly specific electrical and physical profile. It’s a two-pole Type JXD2-A molded-case circuit breaker with a non-interchangeable trip unit and both line-side and load-side lugs. The JXD22B300L is built to last, but replacement work is still about getting the details right. Check the type, amperage, pole count, trip arrangement, interrupting rating, dimensions, and lug setup against the equipment already in place.

Key Features and Benefits

• 300A rating with two poles for installations calling for this specific configuration.
• Type JXD2-A provides an important identifier for checking compatibility.
• Uses a non-interchangeable trip unit.
• Line-side and load-side lugs are included, so the supplied terminal arrangement is clearly defined.
• Well suited to form, fit, and functional replacement where these specifications agree with the existing installation.

Material Compliance and Certifications

The supplied specifications do not include UL, CSA, IEC, RoHS, REACH, or other certification or material compliance information for the JXD22B300L. These approvals should not be assumed. Where a particular certification or standard is required, confirm it against the appropriate product documentation before installation.

Where It Works Best

The JXD22B300L is intended for compatible existing and legacy equipment that calls for a 300A, two-pole Type JXD2-A molded-case circuit breaker with a non-interchangeable trip unit. Having both line- and load-side lugs included is another useful detail when checking the replacement against the existing setup.

Before installation, compare the complete specification—not just the amp rating. The JXD2-A type, two-pole configuration, interrupting rating, physical size, trip-unit design, and lug arrangement should all agree with the requirements of the equipment being serviced.
