277 V single-phase operation is ideal for control panels and automation cabinets, and the SPD clamps and diverts transients to protect sensitive electronics. This translates to reduced downtime, fewer drive faults, and lower replacement costs for motor drives and PLCs. The 200 kAIC interrupt rating provides robust surge handling for commercial and light industrial environments, enhancing reliability in areas prone to lightning or switching surges. The rugged NEMA 4X enclosure enables outdoor use and washdown compatibility, expanding installation options for outdoor cabinets and exposed panels while maintaining accessibility for service. External side mounting simplifies retrofits and allows straightforward installation in cramped or densely populated control rooms. The audible alarm accelerates fault recognition, streamlining preventative maintenance and reducing MTTR. The SPC series warranty and UL 1449 listing reinforce long-term reliability and regulatory compliance, delivering a lower total cost of ownership for OEMs and operators. Long-term value is further realized through compatibility with existing Eaton SPC devices and standard control panel architectures, supporting scalable protection for growing automation environments.

FAQs
Installing the SPC200277N3P requires an accessible control panel space with external side mounting capability. Ensure the 277 V single‑phase circuit is within the device’s rated voltage and current handling. Provide adequate clearance for wiring, secure mounting to a rigid surface, and access to the audible alarm indicator for maintenance. For outdoor or washdown environments, rely on the NEMA 4X enclosure and follow standard electrical codes to maintain enclosure integrity and ingress protection.
A 200 kAIC interrupt rating means the surge protector can safely withstand high transient currents without secondary damage to itself or downstream equipment. In manufacturing floors with heavy motor loads or exposure to lightning, this high rating reduces the likelihood of catastrophic SPD failure, minimizes cascade faults in drives and controllers, and lowers total downtime during surge events. It also supports more robust protection for downstream sensors and control modules against transient spikes.
Yes. The SPC200277N3P is designed as part of Eaton’s SPC surge protection family and uses a standard external side mounting method, enabling retrofit into existing panels that support SPC devices. It’s suitable for 277 V single‑phase control panels and motor-drive enclosures. When upgrading, verify panel clearance, wiring pathways, and compliance with UL 1449 requirements to ensure a seamless installation and ongoing protection across the SPC series.
The SPC200277N3P is UL 1449 listed, confirming its compliance with recognized surge protection standards for transient voltage suppression. It features a rugged NEMA 4X enclosure suitable for wet or dusty environments, broadening installation options to outdoor or harsh indoor locations. The 10-year warranty supports long-term confidence in performance, helping meet reliability targets for automation projects and panel builders.
Total cost of ownership includes the initial unit price, installation labor, and the savings from reduced downtime and fewer component replacements due to transients. The SPC200277N3P’s UL 1449 listing and NEMA 4X enclosure mitigate long-term risk, while the audible alarm supports proactive diagnostics. A 10-year warranty further lowers lifecycle costs by minimizing replacement expenditures and ensuring sustained protection for critical drives and controllers.
