30 amp Deltrol relay 307-1090 RELAY ONAN DELTROL 30 AMP AT 120/240VAC 1PH

What stands out about this unit is that it is made by Brown Boveri Electric Inc., a name I respect.

I appreciate that this General Purpose Relay is made by Tyco Electronics.

You will find that the DC 12V input plays nicely with common bench power supplies and wall adapters.
