The SPM320400Y3Y provides 320 kA per phase protection in a two-module Max series design, delivering robust surge handling that reduces the likelihood of equipment damage and unplanned downtime. This translates to lower maintenance costs and higher production availability in demanding manufacturing lines and critical power feeds. The NEMA 4X enclosure with internal terminal block enables installation in harsh or outdoor environments without extra enclosures, simplifying wiring and speeding up commissioning for panel and MCC installations. A standard surge counter gives real-time visibility into transient activity, supporting proactive maintenance and compliance reporting while minimizing service interruptions. RoHS compliance and certified protections (UL 1449, UL 1283, CSA) ensure regulatory readiness, safe operation, and streamlined audits across facilities. The 15-year warranty (20 years with Eaton registration) reduces total cost of ownership, making it a durable choice for OEMs and end users. With dimensions and weight suited for standard electrical spaces, installation planning becomes straightforward for retrofit or new builds.
