FAQs
SPD120208Y2K is designed for external sidemount installation beside distribution equipment. It uses a standard NEMA 1 indoor enclosure and mounting footprint to enable secure side mounting, with feed-through connections that simplify wiring, labeling, and future upgrades. This configuration minimizes cabinet space interference while preserving easy access for inspection and maintenance.
The device delivers multi-conductor protection with 150 V ratings on L-N, L-G, and N-G, and 300 V on L-L, covering single- and multi-wire configurations. This comprehensive protection reduces transient energy transfer to critical loads such as drives, PLCs, and controls, while maintaining system integrity during surges and line disturbances.
Industries with high-energy transient exposure, including manufacturing lines, data centers, and commercial facilities, benefit most. The 120 kAIC rating provides substantial surge handling for feeders and distribution panels, lowering risk to mission-critical equipment and enabling more reliable uptime in demanding environments.
Yes, SPD120208Y2K is UL 1449 listed, indicating compliance with recognized safety standards for surge protective devices. This certification simplifies regulatory approval, supports code-compliant installations, and aligns with enterprise procurement policies, reducing risk during audits and inspections.
There are no user-serviceable parts; routine inspection during scheduled maintenance is recommended. With a 15-year warranty, procurement teams gain long-term protection against component degradation, helping to stabilize maintenance budgets and ensure continued performance across critical loads in industrial and commercial settings.
