[Amps] Relay derating with frequency?

[Bill Smith]

I have several sealed PCB relays that are rated as
follows:
max switched current-16 amps
max switched power- 480 watts or 4000VA
max switched voltage- 30vdc or 300vac

UL rating- 16 amps at 250vac

Dielectric strength- 1750 Vrms contact to coil and
1000 Vrms across contacts.

I was wondering if and how this relay should be
derated as you increase frequency.  I was thinking
about using them as T/R relays.
73,
Bill
