FAQs
Yes. The P3BFD3045 is designed as a Pow-R-Way III circuit breaker plug-in unit specifically for busway protection. It integrates with typical Pow-R-Way III busway frames to provide modular, expandable protection, enabling quick installation and straightforward replacements without modifying the busway structure.
The unit is a 45A, three-pole breaker with interrupt ratings of 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac. This range supports robust short-circuit protection across diverse industrial loads while maintaining safety margins for peak fault currents in medium-voltage busway systems.
The P3BFD3045 carries UL 857 certification and is ANSI and IEEE certified, with CSA certification as well, and is NEMA compliant. These certifications help ensure regulatory compliance, safer operation, and smoother approvals for widespread industrial deployments.
Plug-in design enables rapid installation and fast field replacements, reducing commissioning time and downtime during maintenance. With a common frame, facilities can stock fewer spare parts and swap units quickly, which lowers labor costs and improves system uptime in busy manufacturing lines or data center racks.
The unit measures 12.36 in in depth, 21.2 in in height, and 5.43 in in width, weighing 25 lb. It is intended for three-pole, F-frame busway installations with 50% integral grounding. When planning mounting, ensure compatibility with existing Pow-R-Way III busway frames and adequate clearance for servicing.
