FAQs
The SPM320208Y3W comes as a two-module surge protection device designed for standard electrical panels. It is compatible with 120/208 V Wye configurations and utilizes a NEMA 4X enclosure with an internal circuit breaker, enabling straightforward panel mounting and integration into existing protection schemes without requiring specialized adapters.
This unit delivers 320 kA per phase protection through its dual-module configuration, providing robust suppression of transient surges. The high rating minimizes voltage excursions on 120/208 V systems, reducing the likelihood of equipment damage, downtime, and nuisance tripping while supporting reliable power delivery to critical loads.
SPM320208Y3W carries UL 1449 certification and CSA listings (Electrical Notice No. 516 Edition 1; CSA Std. C22.2 No. 8-M1986) along with UL 1283. It is RoHS compliant, ensuring restricted use of hazardous materials and alignment with global procurement requirements for regulated environments.
The device carries a 15-year warranty from the date of delivery, with an extended 20-year warranty available when registered on Eaton’s site. This registration-based extension supports long-term protection planning and lowers lifecycle risk for mission-critical installations.
The built-in surge counter provides ongoing visibility into protection events, enabling condition-based maintenance planning. By tracking surge activity, facilities can verify protection performance, justify replacement timelines, and optimize preventive maintenance without interrupting critical operations.
