Special features
Standard with surge counter
Two-module protection with a 400 kA per phase rating delivers robust fault-current handling, reducing catastrophic failures in motors, drives, and controllers. This high-capacity design supports mission-critical loads in manufacturing lines and data centers, where downtime translates into significant costs. The modular architecture also simplifies stocking and spares planning for field upgrades.\nVoltage rating at 240 delta (4W+G) makes this SPD a precise fit for 240V delta systems and high-leg delta configurations, avoiding misapplication and reducing installation errors. The two-module arrangement supports staged protection, enabling phased implementation across large facilities while maintaining clear diagnostic visibility for maintenance teams.\nEnclosure and installation advantages come from the NEMA 4 housing with internal circuit breaker, allowing indoor and outdoor installations without elaborate weatherproofing. The built-in surge counter supports proactive maintenance scheduling and asset management, helping technicians prove protection effectiveness during audits and ensuring ongoing compliance with RoHS- and UL-listed requirements.\nRoHS compliant, UL 1449 and CSA certifications, along with UL 1283 listings, simplify supplier qualification and customer acceptance. This certification mix supports procurement teams seeking reliable, standards-aligned SPD solutions that meet evolving industrial safety and environmental policies.\nWarranty and lifecycle support translate into lower total cost of ownership. A 15-year warranty, extendable to 20 years with registration, aligns with long project horizons and asset management programs common in manufacturing plants, data centers, and utilities.
