Feature: Plug-in Pow-R-Way III design enables rapid field upgrades with minimal wiring. This reduces downtime and labor costs during routine maintenance or expansion. It is ideal for busway feeder sections in large industrial plants. | Feature: Three-pole, 250 A frame with 65 kAIC at 240 Vac provides robust short-circuit protection. This level of interrupt rating safeguards equipment, protects personnel, and minimizes collateral damage during faults. The design supports high-demand loads common in motor control centers and conveyor systems feeding busway networks. | Feature: Neutral and grounding options include 100% Neutral and 50% Integral/Housing Grounding. This configuration supports reliable return paths and flexible grounding schemes to meet diverse electrical codes. For engineers, it reduces design trade-offs when distributing neutral currents across multi-branch busways. In practice, it translates to safer startup sequences and better fault clearance reliability in demanding environments. | Feature: Compliance and certifications cover NEMA, CSA, IEEE, UL 857, and ANSI. This ensures the product meets widely adopted North American standards, easing procurement across multi-site operations and simplifying supplier qualification. It also supports regulatory inspections and helps sustain warranty coverage by demonstrating adherence to recognized safety and performance benchmarks. | Feature: Clear physical footprint and mounting flexibility with dimensions of 34.41 in height, 7.79 in width, 13.29 in depth and a nominal 53 lb weight. These metrics help planners allocate rack space, schedule shipping, and fit the unit into existing busway housings. The unit carries a one-year warranty from installation or 18 months from shipment, providing a predictable lifecycle and cost of ownership.
