Kirb,

The VI/VI+ T/R relay will easily handle that level and current.

The limiting factor in the VI/VI+ T/R circuit are two capacitors (C8/C14) 
across the NO relay 
contacts, which are 50 WVDC devices, not the relay itself.

The relay contacts will handle 12 amps @ 120VAC/28 VDC and 6 amps @ 240VAC.  
The relay is 
manufactured by Million Spot, Inc.  (China)  http://www.millionspot.com/,  P/N 
H500S12-1-C.  I have 
included the mfrs. specs. below for your info.
