Feature: 150 kAIC interrupt rating delivers robust surge tolerance. This capability translates into a lower probability of surge-induced insulation damage and component failure, which in turn reduces unplanned downtime and maintenance costs. Application-wise, it is well suited to service entrances, motor control centers, and power feeds for large industrial equipment in manufacturing plants. Feature: 277 V single-phase operation aligns with many commercial and industrial distribution schemes, delivering targeted protection where loads run on this voltage. Business impact: improved protection without overdesign and wasted headroom, helping facilities meet power quality requirements and avoid nuisance trips. Application: protects lighting circuits, soft-start drives, conveyors, and control panels in warehouses, plants, and facilities. Feature: NEMA 4X enclosure provides rugged, weatherproof, and washdown-ready protection. Impact: enhances reliability in challenging environments, reducing corrosion risk and enabling external mounting where exposure to dust, moisture, or chemicals could threaten performance. Application: outdoor substations, exposed panelboards, and washdown areas in food, water, and chemical processing facilities. Feature: External side mounting supports flexible integration into existing switchgear and enclosures. Impact: simplifies retrofits, minimizes panel disruption, and shortens installation timelines by allowing protection devices to be added without reconfiguring existing layouts. Application: upgrades to legacy systems, retrofit projects in production lines, and new builds where space is at a premium. Feature: UL 1449 listing and a 10-year warranty underline product reliability and safety compliance. Impact: reduces risk during commissioning, lowers total cost of ownership, and provides procurement confidence. Application: critical power feeds, PLC racks, and motor protection schemes in manufacturing, data centers, and infrastructure facilities. Feature: SPC series standard configuration offers consistent performance and straightforward sourcing. Impact: simplifies maintenance planning, reduces training needs, and speeds deployment across campuses or multi-site operations. Application: new deployments and upgrades in automation zones, packaging lines, and process industries where uniform surge protection is essential.

FAQs
SPC150277N1P is designed for external side mounting in standard electrical enclosures with a NEMA 4X rating. Its footprint equals a 5.5 in length, 3.19 in width, and 6 in height, with a weight around 2.5 lb. For retrofits, ensure panel space, proper 277 V supply, and adequate clearance. Follow Eaton’s installation guidelines for wiring, terminations, and overcurrent protection.
The 150 kAIC interrupt rating indicates the SPD can safely withstand and divert extremely large surge currents without compromising its protective function. This translates into lower risk of insulation damage, reduced likelihood of downstream equipment failure, and improved system uptime in environments with high-energy transients such as motors, drives, and large loads.
Yes. The device comes in a NEMA 4X enclosure, designed to resist dust, moisture, and washdown conditions. While it is suitable for harsh environments, verify ambient temperature, chemical exposure, and mounting location. Use appropriate mounting hardware and follow installation best practices to maintain rating integrity and protective performance over time.
The SPC150277N1P is UL 1449 listed, confirming safety and performance compliance for surge protection devices. It carries a 10-year warranty, providing long-term reliability and protection against manufacturing defects. This combination supports regulatory alignment, risk reduction for critical loads, and peace of mind for maintenance planning.
ROI considerations center on reduced downtime, extended equipment life, and fewer replacements for surge-damaged components. With a 150 kAIC rating and UL 1449 listing, facilities can anticipate fewer unplanned outages in motor drives and control circuits. Coupled with a 10-year warranty, projects can justify lower maintenance costs and improved uptime across production lines.
