JXD23B300L - 300Amp Circuit Breaker

JXD23B300L - 300Amp Circuit Breaker

With the JXD23B300L, you have a handful of clear details to check against the breaker already in place. It’s rated 300 amps, has three poles, and carries the JXD2-A type designation. The trip unit is non-interchangeable, and the breaker is supplied with lugs on both the line and load sides. The JXD23B300L is built to last, while keeping replacement decisions grounded in the specifications that matter—amperage, pole count, breaker type, trip arrangement, connections, interrupting rating, and physical size.

Key Features and Benefits

• 300A, three-pole configuration for equipment requiring these exact electrical characteristics.
• The JXD2-A type designation serves as a key reference for checking compatibility.
• Uses a non-interchangeable trip unit.
• Line-side lugs are included.
• Load-side lugs are included.
• 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 information or certifications were provided in the available JXD23B300L specifications. UL, CSA, IEC, RoHS, REACH, or other approvals should not be assumed from the information supplied. For an installation that requires a particular certification or compliance standard, verify that requirement against the appropriate product documentation.

Where It Works Best

The JXD23B300L is best suited to compatible existing and legacy electrical equipment that specifically calls for a 300A, three-pole JXD2-A molded case circuit breaker with a non-interchangeable trip unit. Having both line- and load-side lugs included also gives you another concrete detail to compare with the breaker being replaced.

For replacement work, check the whole set of specifications before installation. The 300A rating, three poles, JXD2-A type, 65 kA at 240VAC rating, trip-unit arrangement, lug setup, and 7.50 × 11.00 × 4.00-inch dimensions should agree with the requirements of the equipment already in service.
