Special features
Standard with surge counter
High surge current rating of 250 kA per phase provides rapid clamping and energy absorption, reducing downstream damage and downtime for critical equipment. This translates to longer motor and drive life, fewer unplanned repairs, and lower maintenance costs in high-energy switching environments. The 480 Delta (3W+G) configuration makes it ideal for modern industrial plants, enabling reliable protection across manufacturing lines and processing facilities. NEMA 4X enclosure with an internal circuit breaker delivers rugged performance in dusty, wet, or wash-down areas, reducing installation risk and panel space requirements while simplifying compliance with safety standards. A standard surge counter enhances visibility for maintenance teams, supporting traceability and regulatory reporting without additional hardware. RoHS-compliant construction further aligns with sustainability goals and reduces the risk of hazardous-substance concerns during audits. The SPD MAX series design ensures compatibility with Eaton protection schemes, enabling scalable upgrades as facility protection needs evolve. Quick installation, proven protection, and OEM-friendly form factor make this solution attractive for panel builders and end users alike.
