JXD63B250 - 250Amp Circuit Breaker

JXD63B250 - 250Amp Circuit Breaker

If you’re looking at the JXD63B250 as a replacement, there are a few details worth checking against the breaker already in service. This is a 250A, three-pole molded case circuit breaker with a JXD6-A type designation and a non-interchangeable trip unit. The JXD63B250 is built to last, with a focus on maintaining the correct form, fit, and function in compatible existing and legacy equipment.

Key Features and Benefits

• 250A, three-pole configuration for equipment requiring these specific electrical characteristics.
• Type JXD6-A provides an important identifier when checking replacement compatibility.
• The non-interchangeable trip unit is designed for applications that require this particular trip arrangement.
• Load-side lugs are included, so you have one fewer connection detail to identify separately.
• A practical choice for form, fit, and functional replacement in compatible legacy electrical equipment.

Where It Works Best

The JXD63B250 is best suited to compatible existing or legacy electrical equipment that specifically calls for a 250A, three-pole JXD6-A molded case circuit breaker with a non-interchangeable trip unit. For replacement work, the combination of part number, type, amperage, pole count, interrupting capacity, dimensions, and terminal arrangement provides a useful checklist for confirming the correct part.
