Special features
Sprinkler-proof plug-in
Feature → Business Impact → Application: Sprinkler-proof plug-in design. It enhances safety and minimizes downtime by enabling quick field replacements in sprinkler environments. This is particularly valuable in tightly spaced industrial facilities where service windows are limited and compliance with fire-safety codes is critical. Application: Pow-R-Way III busway installations in manufacturing plants and data centers where reliable protection and fast maintenance are essential. Feature → Business Impact → Application: Three-pole design with a 110A rating. It provides dependable three-phase protection for standard busway loads, reducing miscoordination risk and improving system uptime. Application: Industrial power distribution networks that rely on modular plug-in breakers for quick swaps during capacity upgrades or fault isolation. Feature → Business Impact → Application: High interrupt ratings of 65 kAIC at 240 VAC, 25 kAIC at 480 VAC, and 18 kAIC at 600 VAC. This broad fault-current tolerance minimizes equipment damage during surges and enhances overall plant safety. Application: Heavy-load facilities where fault currents can vary across supply voltages. Feature → Business Impact → Application: Grounding options of 50% integral or housing grounding. Simplifies grounding schemes in modular busway installations, reducing engineering time and field wiring. Application: New-build or retrofit projects that require flexible grounding to meet site standards. Feature → Business Impact → Application: Compliance and packaging details including NEMA compliance, CSA/IEEE/UL 857 certifications, and compact dimensions. Benefit includes smoother regulatory review, easier procurement, and predictable installation in constrained spaces. Application: Any sprinkler-protected busway system requiring proven certification and documented warranty.
