FAQs
Install the device in a suitable enclosure, connect line, neutral, and protective earth per Eaton's wiring diagram, and verify the internal circuit breaker is correctly set. Confirm voltage rating 127/220V Wye (4W+G) and ensure the enclosure is mounted in a compliant, accessible location. Proper torque on connections and following RoHS guidelines will optimize performance.
The unit provides 120 kA per phase surge protection in a single-module Max series design. It acts as a parallel protector, clamping transient overvoltages to safe levels and diverting surge energy away from connected equipment, helping to prevent damage to drives, sensors, and control panels.
Yes. Its 127/220V Wye configuration, IEC-UL compliance, and rugged NEMA 4 enclosure make it appropriate for data centers and manufacturing environments. The built-in surge counter supports ongoing protection validation, and the internal breaker simplifies integration with existing electrical protection schemes.
The SPM120220Y3R is UL 1449 and UL 1283 listed, CSA certified (including CSA Std. C22.2 No. 8-M1986 and CSA Electrical Notice 516 Edition 1), and RoHS compliant. This combination confirms high safety, reliability, and regulatory readiness for diverse industrial applications.
Eaton offers a 15-year warranty from delivery, with a 20-year warranty if registered on the Eaton site. This warranty, plus the surge counter for visibility and RoHS compliance, helps reduce maintenance costs, extend equipment life, and improve total cost of ownership for mission-critical deployments.
