    I have a 3PDT relay with 12V coil . it has labels
    10A 240VAC
    10A 28VDC

    Is my understanding right that
    each of the three poles has a maximum switching power of 10A or (10 x 28) = 280W in DC device?
    or
    the three poles, altogether as one, has a maximum switching power of 10A or (10 x 28) = 280W in DC device?

    Thanks!

    Each pole is rated to switch and carry 10A at 240VAC or 28VDC with a non-inductive load.
