Feature: 100 kA per phase surge current rating with a 200 kAIC short-circuit capability. Business impact: delivers robust defense against high-energy surges that threaten drives, contactors, and control electronics, reducing unplanned downtime and repair costs. Application: ideal for 480V delta systems and direct bus mounted panelboards used in industrial plants, where switching transients from motors and transformers are common. Feature: 20 kA nominal discharge current with 640 L-G and 640 L-L MCOV, supporting stable protection across phase-to-ground and phase-to-phase paths. Business impact: ensures predictable clamping behavior under repeating transients, preserving downstream equipment like drives, PLCs, and instrumentation. Application: suitable for mixed-load panels and equipment racks in fast-moving manufacturing environments. Feature: Internal integrated mounting simplifies installation and reduces enclosure footprint. Business impact: lowers labor costs, minimizes miswiring, and enables faster retrofits. Application: particularly effective with Direct bus mounted panelboards PRL1a, 2a, 3a, 3e. Feature: Audible alarm with silence button, Form C relay contact, and a surge counter with rest button. Business impact: provides immediate on-site status, supports remote signaling to BMS/SCADA, and enables traceable protection events. Application: ideal for facilities requiring clear alarms and easy monitoring for critical lines. Feature: EMI/RFI filtering up to 50 dB from 10 kHz to 100 MHz. Business impact: reduces electrical noise that can affect CNCs, servo drives, and data paths, improving performance and uptime. Application: data-intensive manufacturing, robotics cells, and control rooms where clean power is essential.
