Eaton SPC100277N8P Surge Protection Device - UL 1449
Part Number: SPC100277N8P
Quick Summary
Eaton SPC100277N8P surge protection device protects single-phase electrical systems from surges in commercial and industrial equipment. Nuisance outages and costly downtime from transients are a common pain point for many plants; this SPD helps minimize that risk. UL 1449 listing, and rugged NEMA 4X enclosure options underpin reliability in harsh environments, while the 10-year warranty supports total cost of ownership. Designed for 277 V, single-phase systems with external side mounting and Form C alarm relay, it delivers measurable uptime and safer control. In practice, engineering teams rely on the SPC series to meet 277 V protection needs across conveyors, pumps, and control panels while staying compliant with established industry standards.

Feature: 277 V single-phase surge protection is tailored for common industrial distribution voltages. Benefit: Reduces damaging transients at the source, protecting sensitive controls and motors, which translates to fewer unplanned outages and lower repair costs. Application: Data centers, packaging lines, and machine centers where a 277 V supply is standard. Feature: 100 kAIC interrupt rating provides robust short-circuit protection. Benefit: Limits temporary fault currents to minimize damage to downstream devices and maintain production continuity. Application: Level 2 and level 3 motor control centers and machine panels where high transient energy is expected. Feature: NEMA 4X enclosure supports outdoor and washdown environments. Benefit: Enables reliable operation in harsh facilities without additional housing, reducing installation time and enclosure costs. Application: Food and beverage processing, chemical plants, and outdoor equipment rooms. Feature: Filtering, Alarm and Form C relay offer real-time fault indication and remote signaling. Benefit: Improves maintenance planning, supports predictive programs, and enables automated interlock decisions. Application: Industrial automation cabinets, panel boards, and safety interlock systems. Feature: External side mounting and compact form factor simplify installation and retrofit projects. Benefit: Speeds up installation, reduces space requirements, and minimizes disruption during upgrades. Application: Retrofit of legacy protection in existing switchgear and control panels. Feature: 10-year warranty and UL 1449 certification establish long-term reliability and regulatory compliance. Benefit: Lowers lifecycle costs and enhances supplier confidence for compliance-driven procurement. Application: OEMs and integrators pursuing durable protection with auditable standards.

FAQs
For external side mounting, ensure the switchgear or panel has adequate clearance for the 5.5 in depth and 6 in height of the unit. Use appropriate mounting hardware and maintain clear access to the alarm relay terminals. Verify that the enclosure location supports the 277 V single-phase input and that wiring conforms to local electrical codes. A protective conduit path reduces EMI and keeps cabling tidy for maintenance access.
The SPC100277N8P provides 277 V voltage rating, single-phase configuration, and a 100 kAIC interrupt rating, with UL 1449 listing. These ratings imply strong transient energy handling, fast response to surges, and compatibility with standard industrial control circuits. The result is improved device and equipment protection, reduced risk of nuisance trips, and better protection for sensitive controllers and motors in typical factory environments.
Yes. The device is explicitly designed for 277 V single-phase systems and supports external side mounting, making it a practical fit for control cabinets on conveyors, pumps, and related equipment. The 100 kAIC rating and filtering capabilities further enhance protection against line disturbances, while the Form C alarm relay supports remote monitoring and seamless integration with plant-wide safety systems.
The SPC100277N8P is UL 1449 listed, confirming surge protection compliance for electrical safety and performance. With a NEMA 4X enclosure rating, it is designed for harsh environments, including washdown and outdoor installations. These certifications and ratings help meet industry standards and regulatory requirements, reduce risk during audits, and support continued operations in demanding industrial settings.
Considerations include monitoring the alarm/ Form C relay for fault signaling, scheduling periodic inspections of the enclosure and wiring, and documenting any surge events for maintenance planning. The 10-year warranty and UL listing contribute to a lower total cost of ownership by reducing replacement frequency and enabling longer asset life, especially in environments with frequent transients or critical uptime requirements.
