FAQs
Installation begins with selecting a suitable 127/220 V Wye system, confirming RoHS compliance, and ensuring the panel has a compatible footprint for the SPM400220Y1X. The unit uses an internal terminal block within a NEMA 4X enclosure for secure terminations. Adhere to CSA/UL guidelines during wiring, verify 400 kA per phase protection, and complete required labeling for safety and future maintenance.
The device provides 400 kA per phase surge current rating and a voltage rating of 127/220 V in a Wye configuration with four conductors plus ground (4W+G). This combination is ideal for protecting industrial panels and critical loads from high-energy transients while maintaining compatibility with standard electrical infrastructure.
Yes. Its 400 kA per phase rating and 127/220 V Wye configuration are well-suited for protecting industrial control panels, motor starters, and drives in harsh environments. The NEMA 4X enclosure, internal terminal block, and robust warranty enhance reliability and simplify integration with existing panel boards and protective schemes.
The unit carries CSA Electrical Notice 516 Edition 1, CSA Std. C22.2 No. 8-M1986, UL 1283, and UL 1449 certifications, with RoHS compliance. These certifications validate electrical safety, performance under surge conditions, and environmental responsibility, supporting compliance programs and procurement standards.
The SPD MAX device carries a 15-year warranty from the date of delivery, extending to 20 years when registered on Eaton’s SPD portal. This extended coverage reduces ownership risk and supports long-term maintenance planning, while Eaton’s documentation and datasheets provide ongoing guidance for installation and service.
