Special features
Standard with surge counter
Two-module Max series design delivers scalable surge protection for multi-load power panels, enabling higher surge energy handling of up to 200 kA per phase and reducing the need for external add-ons. This translates to fewer field components, lower total installed cost, and improved uptime in manufacturing lines where downtime is expensive. The NEMA 4X enclosure with an internal circuit breaker enhances rugged installation in both indoor and outdoor environments, simplifying wiring, maintenance, and safety compliance for panels and outdoor cabinets. Standard surge counter provides real-time monitoring, helping maintenance teams validate protection effectiveness and plan proactive replacements before faults occur, driving long-term reliability and lower lifecycle costs. RoHS compliance ensures ecological responsibility and easier supplier qualifications across regulated facilities. The device is compatible with 277/480 V Wye (4W+G) systems, matches Eaton’s SPD ecosystem, and supports fast, code-aligned installation with fewer interruptions to ongoing production.

FAQs
Install the SPM200480Y3W in a suitable 277/480 V Wye (4W+G) panel or enclosure. The unit features a two-module Max series design and an internal circuit breaker within a NEMA 4X enclosure, simplifying wiring and reducing external components. Ensure proper clearances, connect line and load conductors per Eaton wiring diagrams, and verify the surge counter is reset after commissioning.
The SPD is rated for up to 200 kA per phase with two modules, designed for 277/480 V Wye systems (4W+G). It includes a built-in surge counter and an internal circuit breaker for quick isolation and diagnostics, enabling robust protection of critical loads while minimizing nuisance trips in demanding industrial environments.
Yes. The device is enclosed in a NEMA 4X-rated enclosure with an internal circuit breaker, providing protection against dust, moisture, and environmental contaminants. This makes it suitable for outdoor installations and damp or dusty environments commonly found in manufacturing floors and outdoor electrical cabinets.
The unit carries UL 1449 and UL 1283 certifications, along with CSA standards including CSA C22.2 No. 8-M1986 and CSA Electrical Notice NO. 516 Edition 1. It is RoHS compliant, aligning with modern regulatory requirements and easing supplier qualification across regulated facilities.
The surge counter provides continuous visibility into surge events, enabling proactive maintenance planning and replacement scheduling before failures occur. This leads to reduced unplanned downtime, better asset protection, and a measurable return on investment through lower maintenance costs and extended equipment life.
