Ice Cube Relays…
can be used for smaller load requirement. Often these are used to control contactors that will handel larger load motors,in excess of 15 amp or perhaps a three phase motor.
This is not the ice cube relays limitations but only a few of it’s useful applications.
Cost of these relays varies and are generally less than a contactor or motor starter.
Ice cube relays are not a substitute to a motor starter or contactor,so keep that in mind when useing relays.
In the photo above on the right is a definite purpose contactor and the one on the left is a ice cube relayThis particular relay is a double pole,double throw 120 v relay with 8 pins mounted on a 8 pin base. It is rated a 20 amps.
The photo in the center is a 30 amp three phase motor starter,it has a 24 volt coil and electronic over loads. These are more suited for handling a motors start up and running amps.
It also has a reset button which in the event of an overload or dropped phase the unit will trip and can be reset without replacing fuses.
