Standard with surge counter
High-energy surge rating of 400 kA per phase provides robust protection by absorbing transient energy at the source. This reduces component damage, lowers maintenance costs, and extends equipment life. In machine controls and panel boards, it enables reliable startups and minimizes unplanned downtime. The 127/220 V Wye (4W+G) configuration enables direct integration with common industrial power distributions, reducing wiring effort and risk during retrofits. In existing panels, this compatibility simplifies upgrades and minimizes downtime with familiar wiring schemes. The NEMA 4X enclosure with an internal circuit breaker delivers weather-resistant protection in damp, dusty, or outdoor locations while simplifying protection coordination and spare parts logistics. A built-in surge counter provides immediate visibility into transient activity, aiding maintenance planning. RoHS compliance and certifications (UL 1449, UL 1283, CSA) support regulatory programs and improve procurement confidence, contributing to lower total cost of ownership over the device lifecycle.

FAQs
Check the 127/220 V Wye configuration (4W+G), the NEMA 4X enclosure, and the internal circuit breaker compatibility. The SPM400220Y3V is designed to drop into standard Eaton control panels and common 4W+G distribution schemes with straightforward wiring diagrams, minimizing retrofit effort and panel modifications.
A 400 kA per phase rating indicates the device can safely absorb very high-energy transient events on each phase without compromising protection. This translates to reduced intermittent faults, less downtime, and longer life for connected equipment such as PLCs, drives, and relays.
Yes. The combination of a 127/220 V Wye supply, RoHS compliance, UL/CSA certifications, and a rugged NEMA 4X enclosure makes it well-suited for harsh factory floors, outdoor workstations, and automated lines where durable transient protection is needed.
UL 1449 and UL 1283 cover safety and performance for surge devices, while CSA Electrical Notice No. 516 and CSA Std. C22.2 No. 8-M1986 certify compliance in Canada. RoHS compliance ensures restricted hazardous substances are controlled. These certifications support electrical design validation and procurement compliance.
Eaton offers a 15-year warranty from delivery, extending to 20 years when registered on Eaton’s SPD registration portal. Routine maintenance includes monitoring the surge counter, verifying electrical connections, and inspecting enclosure integrity during periodic preventive maintenance.
