FAQs
The SPC100277N7P is designed for external side mounting, enabling straightforward retrofit into existing panels or enclosures. Its NEMA 4X enclosure protects against dust, water, and washdown, making on-site installation more forgiving in harsh environments. When planning installation, verify clearances for wiring access and ensure the 277 V single-phase supply is present at the panel or enclosure being protected.
SPC100277N7P provides a 100 kAIC interrupt rating and a voltage rating of 277 V for single-phase circuits. This combination supports robust transient suppression for 277 V distribution in industrial settings, helping to protect downstream equipment such as panels, drives, and control circuitry.
Yes. The 277 V single-phase rating and 100 kAIC surge capability make SPC100277N7P well-suited for protecting lighting, HVAC, and motor control panels that operate on 277 V in manufacturing facilities and large facilities with 277 V circuits.
SPC100277N7P carries UL 1449 certification and comes in a NEMA 4X enclosure. UL 1449 confirms transient protection performance and safety compliance, while NEMA 4X ensures ingress protection in demanding environments, supporting plant-wide safety and reliability programs.
With a 10-year warranty and high surge capability, SPC100277N7P reduces maintenance frequency and unplanned downtime. The long-term protection lowers total cost of ownership by extending asset life, reducing replacement costs, and simplifying compliance reporting across facility protection programs.
