PXD63B140 - 1400 Amp Circuit Breaker

PXD63B140 - 1400 Amp Circuit Breaker

If you're looking for a PXD63B140 circuit breaker to match an existing installation, the details matter. This PXD6 molded case circuit breaker is rated at 1400 amps and has a 3-pole configuration with a PD1600A frame. It uses a thermal-magnetic, non-interchangeable trip unit. Interrupting ratings are 25kA at 600VAC, 50kA at 480VAC, and 65kA at 240VAC. The breaker measures 16 inches high, 9 inches wide, and 6.19 inches deep. Those dimensions, along with the frame, amperage, pole count, and trip configuration, are worth checking carefully when you're trying to match a breaker already installed in older electrical equipment. The PXD63B140 is built to last in the applications it was designed for and can be a practical form, fit, and functional replacement when all required specifications match. Lug terminals are not included.

Key Features and Benefits

Material Compliance and Certifications

• No specific material compliance information, agency certifications, or listings were included in the available specifications for the PXD63B140. Rather than assume a certification that may not apply, check the markings on the breaker and the requirements of the equipment where it will be installed.
• For any replacement application, confirm that the breaker ratings and configuration meet the requirements of the electrical system and applicable codes.

Where It Works Best

• The PXD63B140 is best suited to existing electrical equipment that calls for a 1400A, 3-pole PXD6 molded case circuit breaker with a PD1600A frame. This is especially useful when you're maintaining legacy equipment and need to stay with the correct form, fit, and function rather than changing the original breaker configuration.
• Before using it as a replacement, don't rely on the part number or amperage alone. Check the frame size, pole count, dimensions, trip type, voltage, interrupting rating, mounting requirements, and conductor connections against the existing equipment. If those specifications align, the PXD63B140 can provide the configuration the system was designed for.
