Feature to benefit mapping follows a clear pattern: The 80 kAIC interrupt rating provides high surge tolerance, translating to longer mean time between failures and fewer nuisance trips during lightning events. This directly reduces equipment damage costs and maintenance cycles, especially in outdoor or industrial locations where transient energy is common. The external sidemount mounting method enables quick installation on existing panels without extensive cabinet modification, cutting project timelines and enabling faster system upgrades. The NEMA 4X enclosure protects electronics from dust, water, and corrosive environments, increasing panel life and minimizing enclosure-related service calls. The 230/400V wye configuration supports common industrial power networks, simplifying compatibility with motors, drives, and protection schemes while preserving wiring density. A basic feature package keeps initial costs predictable, helping procurement teams manage budgets while meeting safety and performance targets.

FAQs
SPD080400Y1O is designed for external sidemount installation. The installation manual outlines clear steps for mounting, wiring L-N, L-G, and L-L connections, and securing the unit to standard enclosures. Using the sidemount approach minimizes panel modifications, reduces install time, and lowers site risk while maintaining proper clearances and labeling for safe operation.
The device delivers up to 80 kAIC interrupt rating, offering strong transient protection suitable for protecting motors, drives, and other sensitive loads. It clamps surges to safe levels across 320 V-levels and maintains system continuity by absorbing spikes from external utility or switching events, aligning with typical industrial protection requirements.
Yes. SPD080400Y1O carries UL 1449 certification and uses a NEMA 4X enclosure, designed to withstand dust, water spray, and corrosion in challenging environments. This combination supports compliance in many industrial facilities, outdoor installations, and weather-exposed locations, reducing the likelihood of enclosure-related failures.
Best-suited applications include electrical distribution panels, external to distribution equipment, and control panels in manufacturing, process industries, and facilities with significant transient activity. Its 230/400V wye rating and sidemount form factor make it ideal for retrofits and new builds requiring robust surge protection and reliable uptime.
Maintenance is typically limited to periodic inspection of the enclosure and connections, given the 15-year warranty. The device reduces maintenance costs by preventing surge-related damage, lowering unplanned downtime, and extending the life of connected equipment, which translates to a favorable return on investment for facilities with frequent power disturbances.
