Can the 277/480v rated TVS4EMA16A be used on a 120/208v system?.

customer was advised, no, the clamping voltage would be too high to be useful. Using a TVSS that is made for 480/277V on a 208/120V system would not allow the TVSS to provide proper protection. A 208/120V TVSS would clamp at 400V where a 480/277V TVSS would clamp at 800V.
