Special features
Standard with surge counter
High-capacity protection: The SPM300480Y3V delivers 300 kA per phase, rated for 277/480 V Wye systems (4W+G), providing robust clamping for demanding loads. This performance helps protect motors, drives, transformers, and sensitive electronics from damaging lightning transients and switching spikes encountered in manufacturing floors and critical facilities. That translates to fewer unplanned outages and lower repair costs across the lifecycle. Rugged enclosure and simple install: The NEMA 4X enclosure with an internal circuit breaker protects the device from environmental hazards and simplifies wiring, testing, and commissioning. This design minimizes field faults, accelerates startup, and reduces install risk in industrial panels, data centers, and outdoor switchgear.Built-in surge counter: Standard feature for ongoing visibility into surge events, enabling trend analysis and proactive maintenance scheduling. Facilities engineers can correlate surge activity with equipment wear, plan replacements before failures occur, and justify protection investments to management. This capability supports reliability targets and uptime commitments across critical lines.Regulatory compliance and sustainability: RoHS compliant design assists with material restrictions and end-of-life planning, reducing supplier audit risk. For manufacturers with global supply chains, the RoHS footprint simplifies documentation and procurement, easing cross-border compliance.Certifications and scope: UL 1449 and UL 1283 listings, CSA Electrical Notice No. 516, and CSA standards validate performance under worst-case surge conditions. This certification set supports procurement decisions, reduces qualification cycles for new panels, and aligns with safety programs.Installation compatibility and operational value: As a single module in Eaton's Max series, the SPM300480Y3V integrates with standard distribution schemes without complex retrofits. The 277/480 V Wye configuration and built-in diagnostics streamline approvals, spare parts planning, and maintenance workflows. OEMs and retrofit projects gain reliable surge protection with long life and easy service.

FAQs
Ensure the panel is configured for 277/480 V Wye (4W+G) and that there is space for a single-module SPD in the enclosure. Follow Eaton wiring instructions, observe torque specs, and connect the device to the internal circuit breaker. Use the surge counter readings for basic health monitoring and label the installation for future maintenance to minimize downtime.
The 300 kA per phase rating provides robust energy absorption, reducing the likelihood of transient-induced insulation damage, motor winding degradation, and drive malfunctions. This translates to fewer unplanned outages, longer equipment life, and lower repair costs across drives, motors, transformers, and other sensitive electronics in automated lines.
Yes. The NEMA 4X enclosure with an internal circuit breaker is designed for rugged environments, enabling outdoor panels and washdown areas. In addition, RoHS compliance and UL/CSA listings support safe operation across varied temperatures and humidity, making it suitable for outdoor electrical rooms, external racks, and factory floor panels.
The unit is UL 1449 and UL 1283 listed, with CSA Electrical Notice No. 516 and related CSA standards. These certifications verify performance under surge conditions and support regulatory compliance. They also facilitate vendor qualification, project approvals, and warranty validity, reducing procurement risk for engineers and procurement teams.
The built-in surge counter provides actionable data on surge events, enabling predictive maintenance and proactive asset management. Coupled with long warranty terms and RoHS compliance, this supports extended asset life, reduced outage-related costs, and a clearer justification for protection investments in capital projects.
