High surge capacity delivers robust protection for large loads and sensitive electronics. With 320 kA per phase in a two-module Max Series design, it reduces the risk of equipment failure during high-energy events and minimizes downtime in critical production lines. This translates to improved process uptime and lower maintenance costs in automation systems and motor drives. The 480 Delta (3W+G) configuration ensures compatibility with common industrial power distributions, enabling straightforward integration into existing panels and switchgear. The NEMA 4X enclosure with an internal terminal block provides reliable performance in wet, dusty, or outdoor environments, simplifying installation and reducing field wiring time. The built-in surge counter supports proactive maintenance planning by tracking surge events, helping engineering teams anticipate component wear and schedule replacements before failures occur. RoHS compliance and robust certifications underpin regulatory readiness and supply chain confidence, while the unit’s dimensions and weight support practical mounting in tight control cabinets and equipment rooms.
