FAQs
Yes. The SPM320480D3U is designed for 480 Delta (3W+G) configurations and uses a two-module Max series design that fits standard industrial power distributions. Its NEMA 4 enclosure supports indoor and outdoor installations, and the internal terminal breaker simplifies wiring, making integration with existing motor controls straightforward.
The unit delivers up to 320 kA per phase, providing robust transient suppression for every phase of a 480V system. This high rating minimizes the risk of surge-induced insulation damage and equipment failure, translating into lower maintenance costs and reduced downtime for pumps, fans, drives, and other critical loads.
The SPM320480D3U is UL 1449 and UL 1283 listed and CSA certified, with RoHS compliance. These certifications verify protection performance, electrical safety, and environmental compliance, helping you pass regulatory audits, qualify for facility insurance requirements, and maintain smooth supplier qualification processes.
NEMA 4 protection ensures reliable operation in harsh or wet environments, while the internal terminal breaker reduces wiring complexity and panel space needs. This combination simplifies field installation, speeds commissioning, and supports easier fault isolation and routine maintenance without removing the device from service.
By preventing surge-related equipment damage and reducing unplanned downtime, the SPM320480D3U lowers maintenance costs and extends component life. The 15-year warranty (20 years with registration) further protects investment, while the built-in surge counter aids proactive maintenance, delivering measurable uptime improvements and favorable total cost of ownership.
