FAQs
The SPM400220Y1Y is designed for 127/220V Wye (4W+G) configurations, making it readily compatible with standard 4-wire electrical distributions used in many industrial and commercial panels. Its internal terminal block simplifies wiring, enabling faster commissioning and reducing the likelihood of wiring errors during installation. This compatibility supports quick integration into existing control panels or new builds without major system redesign.
This Eaton SPD MAX series unit delivers up to 400 kA per phase surge protection, which means it can absorb large transient events without compromising downstream equipment. By limiting overvoltage exposure, it reduces the risk of equipment damage, minimizes unexpected downtime, and extends the service life of sensitive controllers, drives, and PLCs in harsh industrial environments.
The device carries UL 1449 and CSA certifications, along with RoHS compliance, signaling adherence to recognized safety and environmental standards. For panel builders, this translates to validated performance, easier customer acceptability, and a clearer path to regulatory compliance in many regions, reducing qualification time for new equipment deployments.
Yes, the SPM400220Y1Y uses a NEMA 4X enclosure with an internal terminal block, designed for protection against rain, dust, and cleaning chemicals. This makes it suitable for outdoor cabinets, wash-down areas, and other harsh environments, while still offering straightforward wiring and reliable performance in challenging conditions.
Investing in the SPM400220Y1Y delivers long-term value through a 15-year warranty, extendable to 20 years with registration, and reduced maintenance costs due to high reliability and reduced downtime.
