I'd go for a general purpose 110v DC relay with DPDT three amp contacts. 
Like a Magnecraft 782XBXM4L-110D, Mouser catalog number 528-782X4-110D with 
15 amp contacts. Or 788XBXM4L-110D, 528-788X4-110D with 12A contacts.

Or P&B K10P-11D15-110 Mouser #655-K10P-11D15-110 or KUP-11D15-110, Mouser 
#655-KUP-11D15-110.

Check the dimensions to be sure there's room in the 30L-1.
