Paragraph 1: 125A amperage rating paired with 100 kAIC interrupt capacity at 240 and 480V, and 25 kAIC at 600V, delivers robust fault protection for busway feeders. This performance minimizes downstream equipment damage and shortens recovery time after a fault, supporting higher line uptime in demanding manufacturing environments. Paragraph 2: 100% neutral with 50% internal grounding provides balanced phase currents and safer fault clearing, reducing neutral-ground faults and simplifying wiring while improving protection coordination with upstream devices. Paragraph 3: Three-pole, F-frame plug-in unit is designed for Pow-R-Way III busways, enabling rapid replacement during maintenance and straightforward integration into standard enclosures thanks to its compact footprint (12.36 in L × 21.2 in H × 5.43 in W) and 25 lb weight. Paragraph 4: NEMA compliant and certified to IEEE, CSA, UL 857, and ANSI standards support regulatory compliance, audits, and safe operation across global sites. Paragraph 5: The device is tailored for busway protection, with a catalog number P3BHFD3125GN and plug-in design that reduces commissioning time, lowers total cost of ownership, and offers predictable performance in mission-critical applications.

FAQs
Begin by confirming the unit is the P3BHFD3125GN, three-pole, F-frame plug‑in design intended for Pow-R-Way III busways. Mount the breaker in the enclosure, connect the neutral conductor to the 100% neutral terminal, then wire the protective circuit per the equipment’s wiring diagram. The unit’s dimensions (12.36 in L × 21.2 in H × 5.43 in W) and 25 lb weight support straightforward field placement and quick replacement during maintenance, minimizing downtime.
The P3BHFD3125GN has a 125 A amperage rating with an interrupt capacity of 100 kAIC at 240 Vac and 480 Vac, and 25 kAIC at 600 Vac. This combination provides strong fault current protection for busway feeders while maintaining safe, coordinated trip curves with upstream protection. The 100% neutral option helps maintain balanced currents across all three phases, supporting reliable protection in mixed load environments.
Yes. The P3BHFD3125GN is designed specifically for busway protection in industrial power distribution. Its three-pole configuration, plug-in interface, and F-frame form factor fit typical Pow-R-Way III busways, enabling fast deployment and easy future upgrades as load profiles evolve. Combined with robust certifications and a practical enclosure footprint, it supports high uptime in manufacturing lines and automated systems.
This model carries IEEE Certified, CSA Certified, UL 857, and ANSI certifications and is NEMA compliant. This certification suite ensures compliance with recognized safety and performance benchmarks, simplifies auditing and procurement, and helps meet regulatory requirements across global manufacturing and distribution sites. These standards cover electrical safety, interrupt reliability, and fire protection expectations for industrial power distribution equipment.
Warranty coverage includes one year from installation or eighteen months from shipment, whichever comes first. The plug-in design reduces maintenance downtime by enabling rapid replacement without full disassembly, while the robust interrupt ratings minimize downstream failure and repair costs. For longevity, schedule regular checks of busway connections and neutral wiring to sustain peak performance and return on investment.
