FAQs
Yes. The SPD100480Y2F is designed for use with panelboards and integrates with standard Eaton protection schemes. Its internal mounting and top-terminal design streamline installation, reducing the time needed to bring a protected circuit live in new builds or upgrades.
100 kA per phase indicates the device can absorb a high-energy transient on each phase without compromising protection. For three-phase 277/480V systems, this rating helps guard transformers, drives, and controllers from lightning strikes and switching surges, lowering the risk of insulation damage and data loss.
Key certifications include UL 1449, UL 1283, and UL Listed markings, which verify safety and performance under industry standards. Additionally, compliance with IBC 2006, CBC 2007, and UBC Zone 4 enhances acceptance for commercial and institutional installations.
The audible alarm provides immediate fault notification on-site, while the surge counter and rest button offer a simple way to track events and reset counters after servicing. This enables proactive maintenance planning and reduces unplanned downtime caused by unseen transient damage.
Yes. The device is specified to operate from -40 to 50 °C, supporting installation in challenging industrial environments. Its rugged construction and top-terminal, internal-mounting design contribute to reliable performance and simpler retrofits in demanding facilities.
