Eaton’s SPD Series (Sidemount Versions) Data Sheet
Feature → Business Impact → Application: The SPD100240H1P delivers a 100 kAIC interrupt rating, offering high-energy surge handling that reduces the risk of transient events damaging downstream equipment. This translates to lower replacement costs, less unplanned downtime, and improved process reliability in manufacturing lines and critical power feeds. The 240V delta (4W+G) configuration supports B phase protection for multi-wire systems, making it ideal for heavy-industry motor drives and process controls where unbalanced transients are common. Application: use in 240V delta networks with four-wire systems to shield MCCs, VFDs, and pumps from surge events. Feature → Business Impact → Application: Its NEMA 4X stainless steel enclosure and external side mounting enable quick, secure installation in harsh locations, reducing commissioning time and service calls. Application: outdoor substations, food and beverage facilities, and outdoor equipment closets. Feature → Business Impact → Application: UL 1449 certification and a 15-year warranty provide regulatory assurance and long-term total cost of ownership reductions. Application: facilities facing stringent compliance regimes or asset-intensive environments. Feature → Business Impact → Application: Operating voltage coverage of 150 L-N, 150 L-G, 150 N-G, and 300 L-L ensures comprehensive protection with simple wiring schemes. Application: data centers, municipal installations, and packaging lines needing dependable transient suppression. Feature → Business Impact → Application: Basic feature package compatibility with the SPD Series streamlines procurement, minimizes diversity of parts, and reduces training time for maintenance teams.
