Hi reflectees !
I would not advise anyone to run Vacuum relays with underrated voltage.The HF-current allowance is a direct function of the contact surface, and that is a direct function of contact pressure and in a "Non-latching"-relay that again is a function of coil current. In short words it may result in reduced current ability and burnt out contacts !! Either use correct Voltage or go for "latching-relays" vacuum style.
