PD63B120 - 1200 Amp Circuit Breaker

PD63B120 - 1200 Amp Circuit Breaker

When you're replacing a breaker in an existing electrical system, the details have to match. The PD63B120 is a PD6 molded case circuit breaker rated at 1200 amps with a 3-pole configuration. It uses a PD1600A frame and features a thermal-magnetic, interchangeable trip unit. Interrupting ratings are 25kA at 600VAC, 50kA at 480VAC, and 65kA at 240VAC. Physically, the breaker measures 16 inches high, 9 inches wide, and 6.19 inches deep. Those dimensions, along with the frame, amperage, poles, and interrupting ratings, are worth checking carefully against the breaker you're replacing. The PD63B120 is especially useful for maintaining legacy electrical equipment that was designed around this PD6 configuration. Lug terminals are not included, so the connection requirements of the existing equipment should be confirmed separately. Simply put, this is a straightforward replacement option when the application calls for the PD63B120's specific form, fit, and electrical characteristics. These breakers are built to last when used and maintained within their intended application.

Material Compliance and Certifications

• No specific material compliance, listing, or certification information was included in the available specifications for the PD63B120. Rather than assume a certification applies, check the markings and documentation on the individual breaker if your installation requires a particular listing or compliance standard.
• As with any replacement circuit breaker, a qualified electrical professional should verify the ratings and compatibility with the equipment and applicable electrical requirements before installation.

Where It Works Best

• The PD63B120 1200-amp circuit breaker is primarily suited to existing commercial and industrial electrical systems that use compatible PD6 molded-case circuit breakers. It can be a practical choice for maintenance and replacement work involving legacy switchboards, electrical distribution equipment, or other assemblies designed for this breaker configuration.
  
• For replacement work, don't rely on amperage alone. Check the PD6 type, PD1600A frame, 3-pole configuration, 1200A rating, physical dimensions, voltage and A.I.C. ratings, trip characteristics, and terminal requirements against the existing breaker and equipment. That's the simplest way to determine whether the PD63B120 provides the required form, fit, and function for the job.
