FAQs
The P3BEHD3090G is designed as a plug-in unit for Pow-R-Way III busways. Begin by selecting a compatible feeder section with the correct frame (E) and mounting clearance. Remove access covers, align the plug-in terminals with the busway interface, and secure with the standard hardware. Ensure the unit is properly grounded (50% Internal grounding) and confirm clearance for the 12.36 in depth, 21.2 in height, and 5.43 in width. Verify amperage rating and interrupt rating match system requirements, then reattach covers and perform a controlled energization test per Eaton guidelines.
The P3BEHD3090G provides a 90 A amperage rating with an interrupt rating of 18 kAIC at 240 VAC and 14 kAIC at 480 VAC. This combination supports reliable fault current interruption for 3-phase loads while maintaining coordination with Pow-R-Way III busways and downstream protection devices.
Yes. For 480 VAC systems, the P3BEHD3090G offers a 14 kAIC interrupt rating, aligning with typical industrial protection requirements. Its 3-pole configuration and 50% internal grounding support stable operation in high-voltage busway networks, making it suitable for data centers, manufacturing lines, and other heavy-duty environments.
The unit carries IEEE Certified, CSA Certified, ANSI, and UL 857 certifications, along with NEMA compliance. These marks indicate broad regulatory acceptance, interoperability with other equipment, and suitability for regulated industrial facilities across multiple regions.
As a plug-in protection module, the P3BEHD3090G enables rapid replacement without extensive rewiring, reducing downtime during maintenance. Its compatibility with Pow-R-Way III busways simplifies upgrades and extensions, supporting scalable power management and potentially lowering total cost of ownership through streamlined service and reduced spare-part diversity.
