  • Model: R30A-24


Product Description:

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 normal open (NO), 24VAC coil voltage, and rates up to 30A of load. It is shipped with 4 insultaed connector as shown in the picture. The output connector is good for 14 ~ 16 AWG wire. 

Four PIN connectors are included. 

Wiring for R30A relay. NC terminal is not available on R30A-24

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.
