Eaton SPM160220Y4R Surge Protection Device - UL 1449
Part Number: SPM160220Y4R
Quick Summary
Eaton SPM160220Y4R Surge Protection Device protects critical switchgear and control panels from damaging surges in industrial facilities. Power disturbances can trigger nuisance trips, shorten component life, and drive maintenance costs; this SPD helps keep uptime by diverting surge energy away from vital loads. UL 1449 listing and a rugged NEMA 4 enclosure with an internal circuit breaker support reliable performance in harsh environments, while its 127/220 V Wye rating covers common industrial power systems. Designed for compatibility with Power Xpert SPD ecosystems and other protective architectures, it delivers robust protection, straightforward installation, and long-term operating cost savings.

FAQs
Plan for a 127/220 V Wye supply, route to ground through the 4W+G connection, and accommodate the 9.5 in L x 15 in W x 17.05 in H footprint (weight 52 lb). Use the internal circuit breaker for fault isolation and ensure proper mounting in a NEMA 4 environment to maintain rating. Verify UL 1449 compliance and coordinate with NEC/IEEE protection guidelines during retrofits or new installations.
The device provides 160 kA per phase surge current protection, designed to absorb high-energy transients from events like utility faults or switching disturbances. This rating supports reliable protection for critical loads such as MCCs and motor drives when coordinated with upstream protection devices.
Yes. The unit uses a NEMA 4 enclosure, enabling mounting in outdoor or harsh indoor environments with dust, rain, or moisture exposure while maintaining protection performance as specified by UL 1449.
UL 1449 listing confirms the device meets standardized surge protection performance and safety requirements, providing confidence in reliability, regulatory compliance, and safer integration into electrical protection schemes.
The SPM160220Y4R is designed for compatibility with Power Xpert SPD architectures, enabling streamlined installation and centralized protection management. ROI comes from reduced downtime, extended equipment life, and lower maintenance costs due to improved surge mitigation in critical plant assets.
