Three-pole protection with a 70 A rating using the HFD frame provides targeted protection for mid-size busway branches. The business impact is more reliable outages control and reduced nuisance trips, which translates to less unplanned downtime. In practical terms, this is well-suited for Pow-R-Way III busway installations in manufacturing floors and distribution centers. High interrupt rating of 100 kAIC at 240 and 480 Vac (and 25 kAIC at 600 Vac) gives robust short-circuit protection. The business impact is enhanced equipment safety and minimized arc-fault exposure, lowering repair costs after faults. This capability is especially valuable for critical lines feeding motor loads and process equipment. 50% internal grounding simplifies the grounding approach and reduces wiring complexity. The business impact is faster installation and easier compliance with grounding standards, resulting in lower field labor costs. Application: new builds and retrofits where busway plug-in units must meet tight grounding requirements. Compliance and certification—NEMA, IEEE, CSA, ANSI, and UL 857—provide regulatory assurance and broad interoperability. The business impact is faster permit approvals and less risk during audits. This is particularly beneficial in facilities with mixed equipment from multiple vendors and strict procurement policies. Space-conscious dimensions—12.36 in length, 21.2 in height, 5.43 in width, and a 25 lb weight—enable flexible panel planning. The business impact is more efficient use of enclosure real estate and easier rack integration. Application: retrofits and new builds where footprint matters. Plug-in design accelerates maintenance and spare-parts strategy. The business impact is reduced downtime during replacement and a simpler inventory strategy, which lowers total cost of ownership over the equipment lifecycle. This is especially valuable for ongoing upgrades to Pow-R-Way III busways in dynamic facilities.

FAQs
To install, verify the catalog number P3BHFD3070G and ensure the 3-Pole 70A rating matches your busway design. Align the plug-in unit with the Pow-R-Way III busway interface, secure mounting, and connect conductors per the enclosure and grounding plan. Confirm 50% internal grounding configuration and follow all safety procedures to minimize downtime during replacement.
The unit provides 70 A continuous rating with a 100 kAIC interrupt rating at 240 Vac and 480 Vac, plus 25 kAIC at 600 Vac. Use the higher interrupt rating for systems with high short-circuit potential or where motor inrush and fault currents approach the device’s limits to protect downstream equipment.
Yes. It is NEMA compliant and carries IEEE, CSA, ANSI, and UL 857 certifications, ensuring regulatory alignment and broad interoperability across typical industrial environments and mixed-vendor deployments.
The unit supports 50% internal grounding, which simplifies wiring and reduces field labor. When designing the panel, ensure the internal grounding path is correctly terminated to maintain safety and system integrity, and verify compatibility with the busway grounding scheme already installed in your facility.
Plug-in design enables quicker maintenance and straightforward spare-parts strategy, reducing downtime during replacements. The compact footprint and modularity support scalable expansions, potentially lowering total cost of ownership through reduced field labor, faster upgrades, and easier retrofits in evolving industrial facilities.
