(OP)
I am looking for a dependable relay with the following characteristics...
-24V Coil Voltage
-Less than 30mA through the coil
-The current rating through the contacts must be 2 - 3 amps
-Contact must also support 24V
-Normally Open Contact
The relay needs to be NO. During 99% of operation the relay contacts will be closed because the coil will be continuously energized. When that one rare occurence comes up where the coil loses voltage, then I want the contact to go back to its normally open state.
I've looked on digikey and found a few power relays, but I just thought I'd ask as far as other ideas or second opinions.
Thanks!

Host of options out there, I found a few in Allied's catalog, for example Magnecraft/Struther-Dunn 276AXXH-24D, a SPST-NO with 10A contact rating at 30VDC, 24VDC coil at 2880 ohms (about 9ma coil current to engage). Pins at 0.1" spacing for PCB mounting.
Could you go with a NC relay and skip the use of the ice cube relay?

I believe a solid state switch would work as well provided you can use a heat sink. What type of rating does the ice cube relay have? As suggested, you may be able to eliminate it.
RE: Relay Suggestions
I am looking for a PCB SSR - control voltage 0-10VDC, switching AC load, 4-5A. I have found some, crydom, crouzet, tyco but they are too big. I need something .5" x .3" x .3
Any ideas?
