FAQs
The SPM320208Y1Y uses a two-module Max series design with an internal terminal block, compatible with 120/208V Wye (4W+G) systems. Plan the wiring by routing hot lines to the protected terminals and connecting the ground path to the well-labeled G terminal. Use short, color-coded conductors and follow the enclosure’s sealed access for wiring to minimize corrosion and leakage paths. This approach reduces commissioning time and improves protection reliability.
A 320 kA per phase rating indicates the SPD can safely absorb very large transient currents per phase without degradation, prioritizing protection for critical loads. This rating supports multiple high-energy surges common in data centers, manufacturing lines, and large HVAC drives. For best results, coordinate the SPD with upstream protection devices and ensure the panel’s bus connections and conductors can handle the energy transfer without overheating.
Industries with high transient exposure, such as data centers, automation floors, and process manufacturing, benefit most. Equipment like programmable logic controllers, VFDs, drives, sensors, and communication gear are protected against damaging surges. The NEMA 4X enclosure supports outdoor or damp environments, making it suitable for storefronts, outdoor equipment rooms, and exposed industrial panels.
This model is certified to UL 1283 and UL 1449, with CSA Electrical Notice No. 516 Edition 1 and CSA Std. C22.2 No. 8-M1986, and RoHS compliant. These certifications validate electrical safety, performance under surge conditions, and material restrictions, reinforcing reliability. The product carries a 15-year warranty from delivery, doubling to 20 years when registered on Eaton’s site, which supports long-term maintenance planning.
The built-in surge counter provides a tangible maintenance metric, enabling timely inspections and component replacement before failures occur. Coupled with a long warranty, it reduces unplanned downtime and repair costs while preserving asset life. For ROI, combine energy protection with reduced data loss, less downtime, and extended equipment life across critical loads in industrial facilities.
