Plug
The P3BFDB3020 is a three-pole plug-in unit built on the Pow-R-Way III design, delivering a compact F-frame protection solution for busway systems. Three-pole configuration provides true three-phase protection, reducing miswiring risk and ensuring reliable phase balance; the modular plug-in design speeds installation and future upgrades in dense facilities. The 20A rating is matched with 18 kAIC at 240 Vac and 14 kAIC at higher voltages, delivering strong fault-current handling while maintaining selectivity for downstream devices; this improves equipment longevity and reduces downtime during faults in high-load applications. Grounding Options are 50% integral or housing, simplifying code compliance and safe fault paths within modular busways. The unit weighs 25 lb with dimensions 12.36 in L × 21.2 in H × 5.43 in W, enabling straightforward handling and mounting in standard enclosures. Compliance is assured through UL 857, CSA, IEEE, and ANSI certifications, supporting audit-ready safety and performance. This plug-in breaker integrates seamlessly with Busway applications, delivering installation-time reductions, easier replacement, and scalable protection for growing facilities.
