High surge capacity translates to real-world protection. The SPM100480Y1T handles up to 100 kA per phase, absorbing transient energy before it reaches sensitive motors, drives, and control electronics. In heavy industry, this reduces the risk of nuisance trips and unexpected equipment downtime, especially where grid disturbances or lightning strikes are common. Rated for 277/480 V Wye (4W+G), the SPD MAX aligns with common North American industrial power distribution, simplifying system design and procurement. Its compatibility reduces engineering time and ensures consistent performance across multiple lines, from machine cells to large drives. Users gain confidence that protection remains intact as their voltage profiles evolve. Enclosed in a NEMA 4 enclosure with an internal terminal breaker, it withstands harsh environments and simplifies wiring. The integrated breaker shortens wiring tasks and minimizes external components, speeding up installation and servicing. This design supports safer maintenance and easier replacement without rewiring the entire protection scheme. UL 1283 and UL 1449 certifications, plus CSA Electrical Notice No. 516 and CSA Std. C22.2 No. 8-M1986, validate performance under real surge conditions. These listings help pass audits and meet industry standards for manufacturing floors, data centers, and utility zones. The certifications also support smoother supplier qualification and product acceptance by electrical engineers. Warranty protection extends to 15 years, with 20 years available upon online registration, reducing lifecycle risk and providing planning certainty for preventive maintenance. The unit’s dimensions and weight—9.3 in length, 14.91 in width, 17.5 in height, and 50 lb—facilitate fitment in standard protection cabinets and retrofit projects.

FAQs
Yes. The SPM100480Y1T is designed for 277/480 V Wye (4W+G) configurations and integrates with standard industrial panels and switchgear. It supports single-module installation and aligns with common enclosure practices, simplifying replacement and maintenance while ensuring proper clearances and mounting per Eaton installation guidelines.
The device provides up to 100 kA per phase surge current, delivering fast transient suppression to protect downstream loads such as motors, drives, and control panels. It is RoHS compliant and certified to UL 1283 and UL 1449, offering reliable performance under typical industrial surge events and aiding maintenance planning.
Certifications include UL 1283 and UL 1449, CSA Electrical Notice No. 516 Edition 1, and CSA Std. C22.2 No. 8-M1986. These listings ensure regulatory compliance, streamline audits, and support safe operation in manufacturing, utilities, and data-center environments. They also facilitate supplier qualification and project approvals for regulated facilities.
The internal terminal breaker provides an integrated disconnect, reducing the need for external protective devices and simplifying wiring. This speeds up installation, improves wiring clarity, and enables safer maintenance by allowing rapid isolation of the protected circuit without accessing the main panel.
By minimizing surge-related equipment failures and extending the life of motors, drives, and control electronics, the SPD MAX lowers downtime and maintenance costs. The long warranty, 15 years (20 with registration), further reduces lifecycle risk, delivering a favorable return on investment in facilities with variable power quality or critical production lines.
