PXD63B160 - 1600 Amp Circuit Breaker

PXD63B160 - 1600 Amp Circuit Breaker

The PXD63B160 is a 1600A, 3-pole molded-case circuit breaker for electrical equipment, designed around the PXD6 breaker type and the PD1600A frame. If you're replacing a breaker in an existing system, those details matter just as much as the amperage. This model uses a thermal-magnetic, non-interchangeable trip unit and is rated 25k AIC at 600VAC, 50k AIC at 480VAC, and 65k AIC at 240VAC. Its dimensions are 16 inches high, 9 inches wide, and 6.19 inches deep. The PXD63B160 is a solid fit for compatible legacy electrical equipment where the goal is to maintain the original form, fit, and function rather than change the system configuration. It's built to last when used in the application for which it was designed. One detail to keep in mind: lug terminals are not included, so terminal requirements should be checked separately before installation.

Material Compliance and Certifications

• Material compliance and certification information was not provided for the PXD63B160, so no specific UL, CSA, RoHS, or other certification claims should be assumed. Check the markings and documentation supplied with the individual breaker when a particular listing or certification is required.
• As with any molded case circuit breaker installation, compatibility and applicable electrical code requirements should be confirmed by qualified electrical personnel.

Where It Works Best

• The PXD63B160 makes the most sense for existing electrical distribution equipment designed for a PXD6 or PD1600A-frame circuit breaker, with the corresponding electrical characteristics. It's particularly relevant for commercial, industrial, institutional, and facility applications where an existing breaker needs to be matched as closely as possible.
• And here's where it's worth being careful: 1600 amps and three poles don't tell the whole story. When evaluating the PXD63B160 for an existing system, check the breaker type, frame, dimensions, voltage, interrupting rating, trip configuration, and connection requirements. Matching these specifications helps ensure the breaker is appropriate for the equipment rather than simply being similar on paper.
• Because lug terminals are not included, you'll also want to confirm the required terminal arrangement for the existing installation. For compatible PXD6 equipment, the PXD63B160 provides the specific electrical and physical configuration needed to keep the original system in service.
