Sprinkler-proof plug-in
Three-pole F-frame design delivers balanced protection for busway-fed power systems while maintaining compatibility with Pow-R-Way III installations. The 125A amperage rating and 200 kAIC interrupt capacity at 240 VAC provide robust protection for motor loads and distributed circuits, with scalable performance at higher voltages to support mixed-use facilities. This translates to reduced arc-flash risk, minimized nuisance trips, and improved uptime across critical processes. The sprinkler-proof plug feature minimizes exposure to moisture and dust in damp plant rooms or sprinklered environments, enabling safer maintenance windows and extending service intervals. With 50% internal grounding, wiring complexity is reduced and fault paths are streamlined, cutting wiring hours and potential human error during installation. Certifications such as UL 857, CSA, IEEE, and ANSI ensure regulatory compliance and cross-regional interoperability, allowing quick panel upgrades without requalification. The product’s compact footprint and modular design simplify retrofit projects, lowering field labor costs and facilitating phased implementation. Warranty terms (one year from installation or 18 months from shipment) provide a clear business value by reducing long-term maintenance risk. In practice, the unit is well-suited to busway distribution in warehouses, manufacturing floors, and heavy industrial facilities, where reliability, fast serviceability, and safety standards drive total cost of ownership improvements.
