SPC
The SPC120480Y5P delivers a robust 120 kAIC interrupt rating, which means transient events are contained before reaching sensitive downstream equipment, reducing the likelihood of motor stalling or control relay damage. This directly translates to lower repair costs, fewer outages, and longer asset life in demanding environments such as automotive assembly lines and packaging plants. It is engineered for 277/480V Wye systems, ensuring compatibility with most industrial power distribution setups while maintaining consistent protection across feeders and panels. The NEMA 4X enclosure provides weather- and wash-down resistance, enabling installation in outdoor or harsh indoor locations without compromising safety or performance. External side mounting simplifies retrofits and panel upgrades, minimizing downtime during upgrades and enabling clean integration with existing busways and enclosures. Audible alarm and Form C relay offer immediate fault signaling to operators and control systems, enabling proactive maintenance and faster fault isolation. The SPC series design supports straightforward commissioning, reduces spare part inventories, and aligns with UL 1449 compliance requirements, helping procurement teams meet industry standards and maintain a low total cost of ownership.

FAQs
The SPC120480Y5P is designed for external-side mounting, enabling straightforward integration into existing distribution layouts without significant panel modifications. Its 277/480V Wye rating matches common industrial power architectures, simplifying retrofits in manufacturing lines and data centers while maintaining full surge protection performance. This reduces installation time and associated downtime during upgrades.
A 120 kAIC interrupt rating indicates the device can safely interrupt high-energy transient events up to 120 kiloamps on a per-phase basis. This translates to superior protection for downstream equipment, minimized risk of damage to breakers and drives, and lower repair costs after surge events in high-demand environments like automation cells and material handling systems.
Yes. The SPC120480Y5P features a NEMA 4X enclosure, which is designed for moisture, dust, and wash-down conditions. This makes it suitable for outdoor installations, wet or dusty industrial floors, and exposed electrical rooms, ensuring reliable protection without additional enclosure modifications.
Industries with critical load protection and high transient risk benefit the most, including data centers, automotive manufacturing, packaging, and process automation. The device protects power distribution panels, switchgear, drives, and controllers operating at 277/480V, supporting uptime, longer asset life, and improved maintenance predictability.
The SPC120480Y5P carries a 10-year warranty and UL 1449 listing, providing long-term assurance and regulatory alignment for surge protection programs. Its audible alarm and Form C relay also support fault signaling to control rooms, aiding quick root-cause analysis and reducing mean time to repair (MTTR) when transients occur.
