FAQs
The SPM120400Y3R is a single-module SPD from the SPD MAX series designed for 230/400 V Wye systems. Install in a standard electrical panel with proper bus connections and space for a 9.3 in depth, 17.5 in height, and 14.91 in width enclosure. Ensure clearance and grounding as per local codes. Mounting should align with the internal circuit breaker placement and the device's RoHS compliance.
Yes, the device is specified for 230/400 V Wye (4W+G) configurations and provides up to 120 kA per phase protection. This rating supports protection for critical loads in industrial panels, data paths, and manufacturing equipment against transient surges from utility lines or switching events.
The unit carries UL 1449, CSA Std. C22.2 No. 8-M1986, CSA Electrical Notice NO. 516 Edition 1, and UL 1283 approvals. It is RoHS compliant and meets industry standards for electrical protection devices, making it suitable for regulated facilities and cross-border deployments.
The SPM120400Y3R comes with a 15-year warranty from the date of delivery, 20 years if registered on Eaton's SPD portal. This extended protection reduces total cost of ownership and minimizes replacement cycles in large-scale deployments across industrial facilities.
The built-in surge counter provides ongoing event data, enabling trend analysis and proactive maintenance planning. By correlating surge activity with equipment wear, facilities can optimize protection schedules, justify ROI for SPD investments, and improve uptime without invasive monitoring.
