What voltage does the cap have?
40Vdc or 60Vdc or 100Vdc
That is the minimum rating for the relay.
The "load" seen by the relay is a resistor.
The easiest load there is.
The current seen by the relay is the peak capacitor voltage divided by the resistor value.
Usually milli-amperes.
Specifying a relay to switch on the bleeder resistor is the easiest job ever.
But, there is a trap being set:
The relay contacts should be open just before the capacitor starts to charge up.
Otherwise the relay contacts have to be specified for breading a DC current and that is very onerous !!!!!!!!!!!!!!
