Product FAQs
5 answersWhat legacy Cutler-Hammer circuit breaker does the PDG53K1200E2NN replace?
This Power Defense Frame 5 breaker serves as the modern, upgraded replacement for the legacy ND31200T52W molded case circuit breaker.
Can I install this breaker in an older Pow-R-Line panelboard?
Yes, the PDG53K1200E2NN is designed for unit mounting and is fully compatible with Eaton Pow-R-Line panelboards, as well as standard switchboards and Power Defense enclosures.
What is the acceptable wire size range for the terminals on this 1200A breaker?
The factory-installed lugs are designed to accept conductors ranging from 4/0 AWG to 500 kcmil. Because this is a 1200A frame, multiple conductors per phase are required to meet ampacity codes.
How does the electronic trip unit handle harmonic distortion in industrial environments?
The integrated PXR 20 LSI electronic trip unit utilizes true RMS sensing. This ensures accurate current measurement and reliable overcurrent protection even when non-linear loads introduce harmonic distortion into the system.
Does this breaker support remote monitoring and testing?
Yes, the PXR 20 electronic trip unit features a micro-B USB port for use with Eaton's Power Xpert Protection Manager (PXPM) software. This allows technicians to safely test, configure, and troubleshoot the breaker.
