FAQs
The SPC160277N3P is designed for external side mounting on standard panels and switchgear. It supports single-phase 277 V circuits with an impressive 160 kAIC interrupt rating, making it suitable for protecting typical industrial control panels, motor drives, and distribution boards without extensive cabinet alterations. Installation follows common SPD practices and aligns with Eaton's datasheet guidance for straightforward retrofits.
This unit carries UL 1449 safety certification, indicating compliance with recognized surge protection standards. It offers a 160 kAIC interrupt rating and a 277 V operating voltage, with a rugged NEMA 4X enclosure to withstand challenging environments. The combination supports reliable protection across industrial panels and critical loads while meeting safety and performance benchmarks.
Yes. The NEMA 4X enclosure is designed for outdoor installations and washdown environments, delivering weather resistance and protection against dust, moisture, and incidental contact. While outdoor use is supported, ensure proper enclosure location with adequate ventilation and consider ambient temperature limits when sizing for continuous operation in hot climates.
The SPC160277N3P carries a 10-year warranty and uses an audible alarm to indicate fault conditions. Routine visual inspections and monitoring of alarm signals help prevent undetected protection failures. For end-of-life guidance or fault replacement, consult Eaton’s specification sheet and service recommendations to schedule timely upgrades and maintain continuous protection for critical equipment.
Deploying the SPC160277N3P reduces the financial impact of transient surges by protecting drives, controllers, and panels from damage, which lowers downtime and maintenance costs. The high 160 kAIC rating supports robust protection for high-energy events, extending equipment life and reducing replacement expenses, delivering measurable total cost of ownership savings over the system’s lifespan.
