This relay provides a simple and economical solution for switching any size 24/110/240VAC operated heater or motor. It is single pole, compact, one normally open (NO) and one normally close (NC), 24VAC coil voltage, and rates up to 40A max of load (see specification table below). It is shipped with 5 insulated connectors as shown in the profile picture. The output connector is good for 14 ~ 16 AWG wire.
Wiring for R30A relay. NC terminal is available on R30A-24-C
Compared with ice cub relay, this relay is more compact and expoxy sealed. All the connection are recessed. When connected with insulated connectors, it can be opreated out side of the controller box.
Compared with using an SSR, the advantage of this relay is compact size, no need for heat sink, no heat dissipation issue, real dry cut off and economical price. The disadvantage is limited life time and has to be switched at lower frequency than the SSR. If you don't need super high precision control (within 1 degree) and don't mind a small clicking sound, this relay is a better choice than the SSR.
Note: this relay cannot be triggered by VDC.
