Feature → Business Impact → Application: 100 kA per phase surge protection with a 200 kAIC short-circuit rating minimizes the risk of expensive equipment damage and unplanned downtime in demanding facilities, enabling continuous operation of motor drives and PLCs in manufacturing lines. This translates to higher uptime and lower maintenance costs for panelboards (PRL-C) in process plants and distribution centers. Feature → Application: 277/480 V wye operation (4W+G) provides ready compatibility with most industrial power distributions, reducing the need for adapters and costly retrofits while simplifying procurement for new installations and upgrades. Feature → Application: Internal integrated mounting and right terminals streamline wiring in tight panel spaces, shortening installation time and reducing labor costs during panel retrofits and new builds. Feature → Application: EMI/RFI filtering up to 50 dB from 10 kHz to 100 MHz improves control reliability for sensitive automation systems, yielding smoother PLC operation and fewer intermittent faults in high-noise environments. Feature → Application: Audible alarm with silence button, Form C relay contact, and a surge counter with reset enable proactive maintenance, easy fault tracing, and instant status reporting for facilities teams, helping meet maintenance KPIs. Feature → Application: Wide operating temperature (-40 to 50 °C) and robust UL-listed certifications ensure dependable performance in harsh plant floors and outdoors, supporting compliance with rigorous industry standards and long service life in variable conditions.
