FAQs
For retrofits, plan for external side mounting clearance and wiring access, ensure the enclosure can accommodate a 5.5 inch depth and 3.19 inch width, and verify 488 V single‑phase input compatibility. Use UL 1449 guidelines for proper grounding and enclosure sealing to maintain NEMA 4X protection in day‑to‑day service.
It is rated at 488 V and delivers up to 50 kA of surge protection, making it well suited for 480 V class equipment. UL 1449 certification confirms compliance, and the NEMA 4X enclosure supports installation in demanding environments common to 480 V single‑phase circuits.
The Form C relay provides a ready-made switching/contact interface for signaling or interlocking, enabling straightforward integration with PLCs and motor control circuits. This reduces additional components and wiring, improving response times and simplifying fault indication in critical systems.
The SPC050480N4P is UL 1449 listed and features a NEMA 4X enclosure. These certifications reassure compliance with electrical safety standards and suitability for challenging environments, supporting regulatory requirements for industrial facilities.
With a 10‑year warranty and a strong surge rating, the device minimizes unexpected equipment failures and maintenance downtime, delivering a lower total cost of ownership. Regular inspection of wiring and enclosure seals, along with periodic functional checks, helps sustain performance over many years.
