300 kA per phase surge rating is the core protection statistic of the SPM300480Y3R. This capability absorbs high-energy transients and limits overvoltage exposure to connected equipment, directly reducing insulation damage and PLC faults. In facilities with motor drives and sensitive controls, this translates to fewer unplanned shutdowns and lower repair costs, especially where switching loads spike. 277/480 V Wye configuration provides compatibility with standard industrial power systems. It supports 4W+G configurations and simplifies retrofits by matching common panel voltages, reducing the need for expensive transformers or adapters. This compatibility also helps compliance teams meet electrical safety standards while maintaining system uptime across manufacturing lines. NEMA 4 enclosure with internal circuit breaker ensures robustness in harsh environments and simplifies installation by providing a ready-to-wire protection solution. The internal disconnect enables rapid fault isolation during maintenance windows, reducing downtime and eliminating the need for external switching gear. Surge counter included gives operators visibility into transient activity, supporting predictive maintenance and asset management. With real-time trending and historical data, teams can plan replacements before failures occur and track performance against service-level objectives. Certifications and RoHS compliance underpin regulatory alignment and sustainability goals. UL 1283, UL 1449 and CSA listings confirm market acceptance in North American panels, while RoHS limits hazardous substances. The stated 15-year warranty (20 years with registration) enhances total cost of ownership, lowering life-cycle risk for capital projects. Footprint and warranty context: Product weighs about 50 lb with dimensions 9.3 in depth, 17.5 in height, and 14.91 in width, making it suitable for typical electrical rooms and retrofit projects without excessive space requirements.

FAQs
Install the SPM300480Y3R in a protected space meeting NEMA 4 requirements. Mount per manufacturer guidelines, connect directly to a 277/480 V distribution, and utilize the internal circuit breaker for quick isolation during maintenance. Ensure adequate clearance for cooling and easy access to the surge counter display for monitoring.
The 300 kA per phase rating clamps high-energy transients at safe levels before they reach sensitive equipment, reducing motor drive trips, PLC faults, and relay failures. This rating provides a robust margin in environments with frequent switching or external disturbances, helping sustain production uptime and extending asset life.
Yes. The SPM300480Y3R carries UL 1283 and UL 1449 listings and CSA certification, ensuring safe operation in North American panels. It is RoHS compliant, supporting environmental and regulatory requirements. Always verify local codes and panel compatibility during procurement for seamless integration.
The surge counter provides visibility into transient activity, enabling predictive maintenance and proactive asset management. By analyzing surge history, service teams can forecast capacitor or filter replacements and justify upgrades before failures occur, ultimately reducing downtime and optimizing maintenance spend alongside the device’s long warranty.
The unit measures 9.3 inches in depth, 17.5 inches in height, and 14.91 inches in width, and weighs approximately 50 pounds.
