Special features
Standard with surge counter
The device provides 300 kA per phase protection for 230/400 V Wye systems. This high surge rating dramatically reduces equipment damage during large transients, lowering downtime and warranty costs while protecting critical drives, PLCs, and control panels. It is designed for industrial environments where reliable protection translates directly to improved uptime and predictable maintenance budgets. The NEMA 4 enclosure with an internal circuit breaker offers robust weather resistance and on-site safety, enabling easy service without removing the unit from a live system in damp or dusty facilities. A built-in surge counter gives maintenance teams visibility into event frequency, supporting proactive replacements before failures occur and reducing unexpected outages. The unit is RoHS compliant and carries multiple certifications (UL 1449, UL 1283, CSA), helping meet compliance demands for regulated facilities. Its compact, single-module form fits standard panel boards and allows straightforward retrofits in existing installations, with compatibility for 230/400 V 4W+G systems. The 15-year warranty (20 years when registered) further lowers lifecycle risk and conclusively demonstrates Eaton’s long-term protection commitments.
