JXD22B350 - 350Amp Circuit Breaker

JXD22B350 - 350Amp Circuit Breaker

The JXD22B350 has a very specific footprint and set of ratings, which helps when you’re trying to replace a breaker already in service. Rather than going by amperage alone, compare these details with the existing breaker and equipment. The JXD22B350 is built to last, and for legacy replacement work, getting the type, size, trip arrangement, ratings, and connections right is what matters.

Key Features and Benefits

• 350A rating with two poles for equipment requiring this specific electrical configuration.
• JXD2-A type designation provides an important reference when checking an existing breaker.
• Uses a non-interchangeable trip unit.
• Load-side lugs are included with the breaker.
• Well-suited to form, fit, and function as a replacement when these exact specifications are required.

Material Compliance and Certifications

Specific certification and material-compliance information was not included in the supplied specifications for the JXD22B350. UL, CSA, IEC, RoHS, REACH, or other approvals should therefore not be assumed. Where a particular certification is required, verify it against the applicable product documentation.

Where It Works Best

The JXD22B350 meets the needs of compatible existing and legacy electrical equipment that calls for a 350A, two-pole JXD2-A molded-case circuit breaker with a non-interchangeable trip unit and load-side lugs.

When matching a replacement, check more than the catalog number. Compare the 350A rating, two-pole setup, JXD2-A designation, trip-unit arrangement, AC/DC interrupting ratings, lug configuration, and physical dimensions to those of the breaker currently installed. That keeps the selection centered on the form, fit, and function the equipment actually requires.
