FAQs
Install the SPM300220Y3X as a single-module surge protector in a 127/220 V Wye system, using the internal terminal block for secure wiring. Mount the unit in a suitable NEMA 4X enclosure location, ensure proper grounding, and verify 300 kA per phase rating matches system fault current. Confirm compatibility with existing 4W+G configurations.
The 300 kA per phase rating indicates the SPD MAX device can absorb substantial surge energy per phase without compromising performance. This reduces the likelihood of transient-induced damage to upstream breakers, drives, and motors, thereby increasing equipment uptime and extending the service life of critical assets in factories, data centers, and processing lines.
Yes. The unit is built in a rugged NEMA 4X enclosure with an internal terminal block, offering moisture and dust resistance suitable for outdoor or damp locations. This design simplifies wiring, minimizes corrosion risk, and supports reliable protection in challenging industrial environments without extra enclosure modifications.
The SPM300220Y3X carries UL 1449 and UL 1283 certifications, plus CSA electrical notices and standards. It is RoHS compliant, aligning with environmental and safety requirements. Expect robust regulatory approval for industrial deployments, minimized compliance risk, and favorable audit outcomes when sourcing for regulated facilities.
Investing in the SPM300220Y3X provides long-term cost savings through reduced downtime and fewer surge-related repairs. The 15-year warranty, extended to 20 years with registration, lowers ownership risk, while features like a built-in surge counter streamline maintenance planning and regulatory reporting, contributing to lower operating costs and improved equipment availability over the asset lifecycle.
