PD63B140 - 1400 Amp Circuit Breaker

PD63B140 - 1400 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the details matter. The PD63B140 is a 1400A, 3-pole molded case circuit breaker with a PD1600A frame and PD6 configuration. It uses a thermal-magnetic design with an interchangeable trip unit, making it suitable for compatible electrical distribution equipment in which the original form, fit, and electrical ratings must be maintained. Interrupting capacity is rated at 25k AIC at 600 VAC, 50k AIC at 480 VAC, and 65k AIC at 240 VAC. The breaker measures 16 inches high, 9 inches wide, and 6.19 inches deep. It's a straightforward choice for technicians and maintenance teams working with equipment designed around this specific breaker configuration. Built to last in its intended application, the PD63B140 can help keep compatible legacy electrical systems in service without changing the original breaker requirements. Lug terminals are not included.

Key Features and Benefits

• 1400A rating for electrical systems designed around this amperage requirement.
• Three-pole configuration for compatible three-pole applications.
• PD6 type with a PD1600A frame for matching existing equipment that calls for this configuration.
• Thermal-magnetic operation provides the circuit protection characteristics specified for this breaker.
• An interchangeable trip unit allows it to be matched to compatible application requirements.
• Interrupting ratings of 25k AIC at 600VAC, 50k AIC at 480VAC, and 65k AIC at 240VAC.
• Clearly documented dimensions help make it easier to check physical fit before installation.
• A practical option for maintaining compatible legacy electrical equipment where the correct form, fit, and function are important.

Material Compliance and Certifications

• No specific material compliance information or certification listings were included in the available product specifications. If your installation requires a particular listing, certification, or material standard, check the breaker label and applicable technical documentation before installation. This avoids making assumptions about certifications that haven't been verified for this specific part.

Where It Works Best

• The PD63B140 makes the most sense when you're maintaining an existing electrical system designed for a PD6 breaker in a PD1600A frame. It's particularly suited to replacement and maintenance work where changing breaker types isn't the goal—you simply need the correct physical configuration and electrical characteristics for the equipment already in place.
  
• Before putting the breaker into service, check the existing equipment carefully. Confirm the 1400A rating, three-pole configuration, system voltage, required interrupting capacity, frame, dimensions, and trip-unit requirements. Also keep in mind that this breaker does not include lug terminals, so the required connection hardware should be verified separately.
  
• For maintenance teams dealing with legacy electrical equipment, that kind of specification matching is often more important than anything else. The PD63B140 is built to last and intended to provide the specified circuit protection function when properly matched, installed, and maintained.
