FAQs
The SPM250220Y1X is designed for Eaton MAX series surge protection and is compatible with standard distribution panels that use a 127/220V Wye (4W+G) configuration. It features an internal terminal block for straightforward wiring and supports ganged configurations where multiple devices serve larger automation systems. It integrates with motor drives, PLCs, and control circuits in typical industrial environments.
A 250 kA per phase rating indicates the device can safely absorb very high-energy transients per phase without channeling excessive energy into protected equipment. This improves equipment uptime by limiting voltage spikes that would otherwise damage drives, PLCs, or sensors. In practice, it enhances reliability for high-demand industrial loads and reduces the risk of unexpected failures during severe fault events.
Yes. The SPM250220Y1X uses a NEMA 4X enclosure, which provides weatherproof and corrosion-resistant protection suitable for outdoor installations and washdown areas. While it is well-suited for harsh environments, ensure installation locations comply with local codes and avoid exposure to extreme chemicals beyond enclosure ratings to maintain long-term performance.
The device carries UL 1283 and UL 1449 listings, CSA Electrical Notice No. 516 Edition 1, and CSA Std. C22.2 No. 8-M1986, along with RoHS compliance. These certifications verify electrical safety, performance under surge conditions, and environmental compliance, simplifying procurement, improving audit readiness, and ensuring safe installation within regulated facilities.
The SPM250220Y1X includes a 15-year warranty from delivery, extended to 20 years when registered on Eaton’s site. There is minimal ongoing maintenance required beyond periodic inspection and replacement after surge events. The long warranty and robust surge capability contribute to lower total cost of ownership by reducing unplanned downtime and preserving downstream equipment.
