FAQs
SPD100400Y1N is configured for external side mounting, which simplifies retrofits and field serviceability by allowing the unit to be installed adjacent to existing distribution equipment. This reduces installation time, minimizes disruption to ongoing operations, and facilitates easier access for inspection, testing, and replacement without dismantling adjacent gear.
The 100 kAIC interrupt rating indicates the SPD can safely withstand and divert high-energy transient surges common in industrial environments. This protects downstream components like drives, PLCs, and motors from damaging overvoltages during lightning events or switching transients, helping to prevent costly outages and equipment failure.
Yes. SPD100400Y1N comes in a rugged NEMA 4X enclosure, designed to resist dust, water, and corrosion, making it appropriate for outdoor locations and washdown environments where harsh conditions are present and protection reliability is essential.
SPD100400Y1N is UL 1449 listed, confirming compliance with established surge protection standards. This certification, combined with the enclosure rating and warranty, provides confidence in performance, reliability, and ongoing support for critical electrical protection in regulated industrial settings.
The 15-year warranty and robust surge protection reduce unplanned downtime and maintenance costs by safeguarding critical equipment. By preventing transient damage to motors, drives, and control electronics, it lowers replacement and repair expenses, improving asset longevity and supporting predictable maintenance budgeting for your facility.
