Special features
Sprinkler-proof plug-in
Sprinkler-proof plug-in design provides enhanced protection in sprinklered environments, reducing water ingress risk and improving uptime for mission-critical loads. This translates to fewer unplanned outages and smoother maintenance windows in data centers, factories, and commercial facilities where busway protection is essential. Three-pole F-frame architecture with a 70A rating and 100 kAIC interrupt capability ensures fast, reliable fault clearing, helping facilities meet short-circuit withstand requirements at 240 and 480 VAC while limiting equipment damage. The unit supports 100% neutral and 50% integral or housing grounding, enabling flexible grounding schemes that simplify retrofits and new installations across existing panels and new builds. NEMA compliance, UL 857, and CSA certification provide regulatory confidence and smoother approval processes, reducing design risk and accelerating project schedules. The plug-in design delivers quick swap-outs and straightforward field service, minimizing downtime during maintenance and upgrades for industrial power distribution systems. With busway compatibility and engineering-grade build, Pow-R-Way III plug-in units like this one help control panel designers achieve compact, code-compliant solutions without sacrificing protection or performance.
