Nearly all units are rated to a minimum of 600V AC/DC, however in some instances they may be less and we encourage you to check with us if you have any questions of your specific model. Otherwise, we offer standard high voltage designs (MXV-Series) rated up to 1500V, 2500V, 3500V but can build custom multi-channel solutions rated up to 5,000V.  Single contact versions (MC-Series) are unaffected by the voltage passing through them, and can handle a theoretically infinite voltage.
