FAQs
Begin by selecting an external-side mounting location within the protected control panel or MCC. Connect the line and load conductors per the wiring diagram, verify proper grounding, and ensure the enclosure cover is securely closed. Use only compatible wiring methods and follow all local electrical codes. After wiring, perform a functional check and verify the audible alarm operates as intended.
Yes. The device is built in a rugged NEMA 4X enclosure designed to resist dust, water, and washdown exposure. This makes it appropriate for outdoor substations, exterior panels, and production-area installations where harsh environmental conditions are common, helping protect the surge protection device and connected equipment.
The SPC050480Y3P is UL 1449-listed, indicating compliance with recognized surge protection standards. It also features a durable NEMA 4X enclosure suitable for challenging environments. The unit carries a 10-year warranty, providing long-term assurance of performance and reliability for industrial applications.
By minimizing damage from transient surges, reducing nuisance trips, and lowering unplanned downtime, the SPC050480Y3P can materially extend equipment life and improve line uptime. Although ROI varies by site, facilities with high transient activity or critical automation benefit from lower maintenance costs, fewer spare parts, and enhanced production continuity.
Facilities with medium to high energy transients across industrial power distribution—such as motor controls, switchgear, and panel boards operating at 277/480V Wye—gain the most from the 50 kA protection. The rating helps absorb surge energy before it reaches sensitive drives, controllers, and sensors, preserving performance and uptime in demanding manufacturing and processing environments.
