45A amperage rating with a three-pole FD plug-in design delivers precise protection for mid-range busway loads. This minimizes nuisance trips and protects upstream equipment, improving uptime for critical manufacturing lines and data centers. 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac provide rapid fault clearance across operating voltages. The result is enhanced equipment protection and reduced arc energy exposure, lowering maintenance costs and downtime in heavy-duty motor and drive applications. 100% Neutral and 50% integral or housing grounding options simplify balancing and grounding in multi-branch busway networks. Engineers gain safer fault paths and easier compliance testing, especially in regulated environments such as food processing and pharmaceuticals. UL 857, ANSI/IEEE, and CSA certifications, along with NEMA compliance, deliver proven safety and interoperability across vendors. This reduces procurement risk and accelerates design reviews for plant upgrades and facility expansions. Compact Pow-R-Way III design with a footprint of 12.36 in length, 5.43 in width, and 21.2 in height, weighing 25 lb, supports easy integration into crowded electrical rooms. Space efficiency and straightforward wiring translate to faster installation and lower freight costs on large projects.
