Feature: The SPC120480D5P offers a 120 kAIC interrupt rating, enabling robust surge energy handling for demanding electrical environments. Business Impact: this resilience translates into fewer transformer and drive failures during large transient events, reducing maintenance costs and downtime across the plant. Application: ideal for 480V delta distribution in industrial panels, motor control centers, and protect-critical feeders from damaging surges that can trigger costly outages. Feature: Audible alarm and Form C relay enable clear remote signaling and fault notification. Business Impact: these signals support faster fault localization, reduce mean time to repair, and enable condition-based maintenance without intrusive manual checks. Application: integrates with plant annunciators, PLC inputs, and remote monitoring systems for proactive protection status. Feature: NEMA 4X enclosure provides rugged protection against dust, water, and washdown environments. Business Impact: lowers risk of corrosive ingress and debris-related failures in harsh manufacturing floors. Application: suitable for outdoor panels, wet factories, and food/beverage facilities where environmental exposure is expected. Feature: External side mounting simplifies retrofits and minimizes panel disassembly. Business Impact: reduces installation time, downtime, and labor costs during upgrades or expansions. Application: ideal for modernization projects in existing switchgear and control panels across industrial facilities. Feature: UL 1449 listing confirms compliance with surge protection standards, while 480V Delta compatibility ensures seamless integration with common industrial networks. Business Impact: streamlines procurement, reduces risk of noncompliant equipment, and supports pass-through regulatory goals. Application: panels, switchgear, and drives in process industries requiring certified transient protection. Feature: 10-year warranty provides long-term support and predictable total cost of ownership.

FAQs
To install the SPC120480D5P, mount using external side mounting on a suitable NEMA 4X panel. Verify 480V delta service, connect line and load per the Eaton diagram, and wire the audible alarm and Form C relay to the control system or PLC. Ensure proper clearance, grounding, and torque specifications are followed for reliable protection.
A 120 kAIC interrupt rating indicates the device can safely interrupt very large surge currents without failing. This capability protects downstream equipment such as motor starters, drives, and control circuits from damaging energy, reducing the risk of component burnouts and unplanned outages. It is suitable for demanding industrial environments with high transient energy events.
Yes. The SPC120480D5P is housed in a NEMA 4X enclosure designed to resist dust, water, and washdown conditions. It is appropriate for outdoor panels and harsh factory floors where environmental exposure is a concern, helping to maintain protection without compromising performance.
The SPC120480D5P is UL 1449 listed, ensuring compliance with recognized surge protection standards. Its 480V Delta rating supports integration with common industrial systems, and the audible alarm plus Form C relay provide monitored signaling that aligns with plant safety and maintenance programs.
Expect reduced downtime and fewer costly repairs due to transient events, thanks to the 120 kAIC rating and robust enclosure. The unit comes with a 10-year warranty, which lowers total cost of ownership by reducing replacement frequency and enabling longer asset life in critical manufacturing assets.
