Feature → Business Impact → Application: The SPC200277N8P provides 277 V surge protection with a 200 kAIC interrupt rating, delivering fast transient suppression that minimizes downtime and equipment wear in industrial controls and commercial power panels. This results in measurable asset protection and reduced maintenance costs, particularly in facilities with sensitive electronics, PLCs, and drive systems. Application: Use in single-phase distributions where external side mounting is preferred, enabling straightforward retrofits and scalable protection for growing sites while maintaining a compact footprint. Feature → Business Impact → Application: Filtering reduces high-frequency noise and improves power quality, translating to fewer nuisance trips and better analytics for energy management systems in manufacturing lines. Application: Ideal for control cabinets and distribution boards where reliable signaling is required. Feature → Business Impact → Application: Alarm and Form C relay enable proactive maintenance, status monitoring, and integration with building management systems, supporting condition-based maintenance and faster fault isolation. Application: Suitable for OEM equipment, panel builders, and service providers seeking clear fault signaling. Feature → Business Impact → Application: UL 1449 listing and NEMA 4X enclosure ensure compliance and rugged durability in harsh environments, reducing the risk of water or dust ingress and extending product life. Application: Harsh industrial spaces, outdoor-rated installations, and moisture-prone environments. Feature → Business Impact → Application: External side mounting simplifies installation in existing enclosures or limited-space panels, reducing commissioning time and project cost. Application: Retrofit jobs and new builds where space and wiring access are constrained. These design choices collectively support improved uptime, lower total cost of ownership, and easier compliance with industry standards, while preserving compatibility with 277 V electrical systems and SPc-series protection strategies.

FAQs
The SPC200277N8P is designed for 277 V single-phase power with a NEMA 4X enclosure and external side mounting. This layout simplifies retrofits in existing panels, reduces wiring complexity, and supports straightforward integration into standard distribution gear without requiring major cabinet modifications.
SPC200277N8P delivers 200 kAIC interrupt rating, UL 1449 certification, and filtration for improved power quality. It includes an Alarm and Form C relay for fault signaling, which facilitates proactive maintenance and rapid issue isolation in critical power paths.
This device is suited for industrial control panels, commercial power distribution, and equipment sharing environments where 277 V systems are used. Its rugged NEMA 4X enclosure and robust surge protection minimize downtime, extend equipment life, and support compliance in harsh manufacturing and processing facilities.
The Form C relay provides a discrete fault signal that can be routed to a building management system or maintenance dashboard. This enables condition-based maintenance, faster fault isolation, and reduced mean time to repair by giving operators a clear, actionable alert when surge events or device faults occur.
Plan for external side mounting in a suitable enclosure, account for the 5.5 in depth and 3.19 in width, and ensure the 277 V supply is correctly wired. Confirm UL 1449 compliance and verify the NEMA 4X rating for your environment. Consider coordinating with panel builders to align with existing protection strategies and wiring schematics.
