FAQs
SPC100277N3P is designed for external side mounting, enabling straightforward integration into most control panels or switchgear enclosures. Its external mounting simplifies service access and replacement, reducing panel disassembly. This mounting approach also helps maintain clearance for wiring, improves heat dissipation, and supports retrofit projects where space and accessibility are critical considerations for engineers and installers.
The SPC100277N3P delivers a 100 kAIC interrupt rating, meaning it can safely interrupt high-energy surges without compromising the protected circuitry. This capability provides enhanced protection for sensitive electronics in critical systems, reducing the likelihood of transient-induced failures. The 277 V single-phase design aligns with common plant and facility power distribution, delivering targeted protection where it is most needed.
This surge protection device is well suited for industrial control panels, equipment rooms, and switchgear in manufacturing, HVAC, and data-center environments. Its NEMA 4X enclosure supports tough conditions, while the audible alarm offers quick fault indication. The SPC series is ideal for new builds and upgrades seeking robust transient protection, reliable performance, and long-term maintenance predictability.
Yes, the SPC100277N3P carries UL 1449 certification, providing recognized safety and performance validation for surge protection devices. It is housed in a NEMA 4X enclosure, delivering weather- and corrosion-resistance suitable for damp or outdoor installations. These certifications and ratings support compliance with industrial electrical standards and help streamline qualification processes for facilities.
With a 10-year warranty, the SPC100277N3P offers strong total cost of ownership benefits, reducing replacement頻 frequency and maintenance surprises. The audible alarm aids proactive maintenance by signaling fault conditions, enabling planned interventions rather than reactive repairs. For ROI, consider reduced downtime, protection of critical loads, and longer asset life across data centers, manufacturing lines, and automation systems.
