Three-pole, F-frame plug-in design provides robust protection with streamlined installation, reducing commissioning time and ensuring consistent phase balance across the busway. This translates to measurable uptime gains and lower risk of nuisance trips in high-demand facilities. The 175A ampacity paired with 100 kAIC interrupt ratings at 240/480 Vac delivers strong short-circuit protection for feeder circuits and critical loads, minimizing equipment damage and downtime in manufacturing lines and data-center feeds. The 100% neutral and 50% integral housing grounding option simplifies grounding schemes, improves fault current paths, and reduces wiring complexity, delivering cost savings during installation and future maintenance. Certifications from NEMA, UL 857, IEEE, and CSA help satisfy stringent regulatory requirements and customer spec sheets, supporting faster approvals in regulated environments. Plug-in unit compatibility with Pow-R-Way III busway systems enables modular expansion and easy replacement, while the three-pole configuration ensures balanced protection across all phases, boosting reliability in power distribution networks. Industry context shows that modular plug-in breakers like this unit reduce spare parts inventory and accelerate change-outs during capacity upgrades, translating to lower total cost of ownership.
