FAQs
Installers should plan for external side mounting in standard 240V single‑phase panels. Ensure adequate clearance for service, route wiring to the device’s terminals, and verify panel space fits the 5.5 in depth and 3.19 in width. The unit’s NEMA 4X enclosure protects against dust and water ingress, enabling outdoor or washdown area installations. Always refer to the Eaton specification sheet for torque values and wiring diagrams to ensure code-compliant, safe retrofit.
A 120 kAIC interrupt rating indicates the SPD can safely interrupt high-energy surge events, protecting downstream components like relays, drives, and controllers from catastrophic overvoltage. In practice, this translates to fewer surge-related failures, extended equipment life, and reduced maintenance costs in demanding applications such as servo drives and high‑inrush motor loads.
Yes. The SPC120240N5P is designed for 240V single‑phase systems common in control panels and MCCs. Its NEMA 4X enclosure and UL 1449 certification support harsh factory environments, while the alarm relay provides real-time fault signaling to maintenance systems. This combination helps maintain uptime and power integrity in manufacturing environments.
The SPC120240N5P carries UL 1449 certification for surge protection and a NEMA 4X enclosure rating for protection against dust, water, and corrosion. The unit also features an alarm and Form C relay to integrate with building or plant monitoring systems, supporting regulatory compliance and traceability in industrial settings.
Projected ROI comes from reduced downtime, longer asset life, and lower maintenance costs due to improved power quality. The alarm relay enables proactive maintenance, and the robust 120 kAIC protection minimizes surge damage to drives and controllers. Coupled with a 10-year warranty, overall life-cycle costs are minimized while safeguarding critical loads.
