For dc voltage applications, the make/break ampere rating for relay contacts can be determined by
dividing 28 VA by the applied dc voltage. For example, 28 VA

÷

48V dc = 0.58A. For dc voltage

applications less than 48V, the make/break ratings for relay contacts cannot exceed 2A. For dc
voltage applications greater than 48V, the make/break ratings for relay contacts cannot exceed 1A.
