PD63B160 - 1600 Amp Circuit Breaker

PD63B160 - 1600 Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, getting the details right matters. The PD63B160 is a 1600A, 3-pole molded-case circuit breaker built on a PD1600A frame and identified as Type PD6. It uses a thermal-magnetic design with an interchangeable trip unit, making it suitable for compatible electrical systems that require this configuration. Interrupting ratings are 25k AIC at 600VAC, 50k AIC at 480VAC, and 65k AIC at 240VAC. The breaker measures 16 inches high, 9 inches wide, and 6.19 inches deep. That gives you several important points to check against the breaker already in your equipment—not just amperage, but also frame size, poles, dimensions, voltage, AIC rating, and trip setup. Lug terminals are not included. For facilities that maintain legacy electrical equipment, the PD63B160 can provide the form, fit, and function required when the application calls for this breaker. It's built to last when correctly matched, installed, and maintained for its intended use.

Key Features and Benefits

• 1600A, 3-pole configuration for equipment designed around these electrical requirements.
• PD6 type with PD1600A frame for matching compatible existing installations.
• Thermal-magnetic operation provides the specified trip functionality.
• Interchangeable trip unit supports the original breaker configuration.
• Rated 25 kA at 600VAC, 50 kA at 480VAC, and 65 kA at 240VAC.
• Clearly defined dimensions make it easier to check physical fit before installation.
• A practical option for maintenance work where matching the existing breaker specifications is important.
• Built to last for its intended application when properly installed and maintained.
• Lug terminals are not included, so terminal requirements should be checked separately.

Material Compliance and Certifications

• Specific material compliance, certification, and listing information was not provided for the PD63B160. These details shouldn't be assumed. If your application requires a specific certification, listing, or material standard, check the markings on the breaker itself and the applicable product documentation before installation.

Where It Works Best

• The PD63B160 makes the most sense in compatible legacy electrical distribution equipment that already calls for a PD6 breaker with a PD1600A frame, 1600A rating, and three-pole configuration. It's particularly relevant when maintenance work requires keeping the existing electrical system's original form, fit, and function.
  
• Before using the breaker as a replacement, compare it with the existing unit and equipment requirements. Check the part number, frame, amperage, number of poles, trip configuration, physical dimensions, voltage, and AIC rating. Since lug terminals aren't included, you'll also want to verify the terminal setup required by the application. The final installation should comply with the equipment requirements and applicable electrical codes.
