400 kA per phase surge rating delivers robust protection against high-energy transients, reducing the risk of failure in drives and controllers and enabling stable production lines in manufacturing and processing facilities. This translates to measurable uptime improvements and lower replacement costs for critical equipment in harsh industrial environments. The NEMA 4X enclosure with internal circuit breaker provides durable, weatherproof protection and simplified maintenance, making it suitable for outdoor panels and wash-down areas while enabling straightforward retrofits in existing switchgear and distribution setups. The 127/220 V Wye (4W+G) configuration ensures broad compatibility with common industrial power layouts, facilitating quick installation in MCCs and control panels without custom wiring. A long-term warranty (15 years, 20 with registration) reduces lifecycle risk and accelerates ROI for project procurement teams. RoHS compliance and multiple certifications support compliance for regulated sectors such as manufacturing, food & beverage, and automation.

FAQs
Yes. The SPM400220Y1V is designed for 127/220 V Wye (4W+G) systems and integrates with standard panelboards, MCCs, and machine control panels. When planning installation, ensure proper clearances, correct wire sizing, and adherence to local electrical codes. The internal circuit breaker simplifies integration by allowing selective tripping and easier fault isolation, reducing downtime during maintenance or retrofits.
The unit provides up to 400 kA per phase surge capacity, enabling it to absorb and divert high-energy transients that would otherwise threaten drives, controllers, and sensitive electronics. This rating supports protection against utility faults and lightning-induced surges commonly encountered in industrial facilities, helping maintain uptime and extend the life of critical equipment.
Yes. The SPM400220Y1V uses a rugged NEMA 4X enclosure with an internal circuit breaker, designed for outdoor installations and wash-down areas. This enclosure protects internal components from dust, water, and corrosion, allowing installation in harsh environments such as manufacturing floors, outdoor substations, and wet process areas without additional housing.
The device is UL 1449 and UL 1283 listed, CSA C22.2 No. 8-M1986 certified, and compliant with CSA Electrical Notice NO. 516 Edition 1, along with RoHS compliance. These certifications support safety, regulatory acceptance, and environmental compliance for regulated industries and global deployments.
Eaton provides a 15-year warranty on the SPM400220Y1V, extending to 20 years when registered on Eaton’s site. This long-term warranty lowers lifecycle risk and reduces maintenance-related downtime, delivering favorable total cost of ownership for projects in automation, electrical distribution, and panel-building environments.
