Feature → Business Impact → Application: The SPD100220Y2N delivers a 100 kAIC interrupt rating, protecting connected equipment from high-energy surges and minimizing unplanned downtime, which translates to reduced maintenance costs and improved uptime for critical lines like CNC machines and PLC-driven conveyors in manufacturing floors. This translates to faster recovery times after events and lower spare-part consumption. Application-wise, it is ideal for external-side installation on distribution panels in industrial settings where robust surge suppression is required. Feature → Business Impact → Application: The 127/220 V Wye (4W+G) voltage rating ensures compatibility with common worldwide distribution schemes, simplifying global deployments and reducing design complexity for multi-site operations. This enables one SPD model to support diverse plant footprints without custom configurations. Application-wise, it suits global facilities requiring consistent surge protection across locations. Feature → Business Impact → Application: A NEMA 4X enclosure provides moisture and corrosion resistance, enabling outdoor or damp indoor environments to maintain protection integrity while reducing enclosure maintenance and replacement costs. This is especially valuable for outdoor pads, protected plant entrances, or humid manufacturing zones. Feature → Business Impact → Application: External side mounting streamlines installation and serviceability, reducing labor time during retrofit projects or new builds. Rapid replacement and minimal panel disruption translate to shorter outage windows and improved project timelines. Application-wise, it supports retrofit integrations with existing Eaton SPD series or standalone surge protection deployments in new builds. Feature → Business Impact → Application: The SPD series features a straightforward package with standard accessories, a long warranty (15 years), and UL 1449 certification, delivering predictable total cost of ownership and regulatory compliance. This reassures procurement and maintenance teams while enabling quicker approvals for capital projects. Application-wise, it’s well-suited for OEMs and integrators looking to minimize risk and maximize protection coverage at scale.
