Special features
Basic
(Feature → Business Impact → Application) 100 kA per phase protection in a single module provides robust transient suppression, minimizing downstream gear damage and unplanned downtime for critical lines in manufacturing and packaging. This translates to lower warranty claims and predictable maintenance windows, improving overall equipment effectiveness (OEE) in automation cabinets and panel boards. The 277/480 V Wye (4W+G) voltage rating ensures compatibility with common plant distributions, reducing engineering changes and enabling rapid deployment across new lines or retrofit projects. In practice, engineers can design with confidence that upstream surges won’t propagate to sensitive drives or PLCs, supporting tighter control of process variables and longer load life. The NEMA 4X enclosure with internal terminal block enables installation in damp, dusty, or outdoor environments without compromising wiring integrity, ensuring a clean, code-compliant install across conveyors and robotic cells. RoHS compliance and strict UL/CSA certifications align with compliance programs and supplier governance, lowering risk during audits and supplier qualification. Its basic feature set delivers essential protection with straightforward maintenance, making it suitable for standard electrical rooms and equipment rooms in mid-sized facilities.

FAQs
The SPM100480Y1X is a single-module surge protection device from Eaton's SPD MAX series designed for 277/480 V Wye systems. It provides 100 kA per phase transient suppression to protect downstream loads like drives, PLCs, and other automation equipment from damaging surges. It is suitable for main distribution panels and dedicated control cabinets in industrial settings.
Installation is straightforward thanks to the internal terminal block design. Mount the unit in a protected or compliant enclosure (NEMA 4X) as part of the panel or cabinet, connect conductors to the internal terminals per Eaton’s wiring diagram, and verify compatibility with your 277/480 V Wye distribution. Proper torque and clearance ensure reliable operation and ease of future maintenance.
The device carries UL 1283 and UL 1449 surge protection certifications, plus CSA Electrical Notice NO. 516 Edition 1 and CSA Std. C22.2 No. 8-M1986. It is RoHS compliant, meeting modern environmental and safety standards while simplifying qualification for regulated industries and spec-driven procurement.
The SPM100480Y1X offers a 15-year warranty from the date of delivery, with a 20-year warranty available when registered on Eaton’s SPD site. This extended coverage helps reduce total cost of ownership and provides long-term protection against surge-related equipment damage in critical automation assets.
Industrial panels, automated lines, and control cabinets distributing 277/480 V benefit most, including motors, drives, and PLC-embedded electronics. By curbing surge-induced outages and extending component life, facilities typically see reduced maintenance costs and downtime, contributing to faster project commissioning and improved overall equipment effectiveness (OEE).
