DPDT stands for (D)ouble (P)ole (D)ouble (T)hrow while DPST stands for (D)ouble (P)ole (S)ingle (T)hrow. The 'poles' are the switches that open and close as current is applied to the coil. The 'throw' indicates the number of switch positions available. For our application a double pole single throw (DPST) relay is sufficient (shown in picture), but many relays include double throws. The poles must support at least 30A "resistive" load at 240V AC. Often the relay will have a second "inductive" current rating which is lower. The coil must be rated for 110-120V AC. Relays may come with or without covers which will not affect the performance or functionality.
A definite purpose contactor may be used instead of a relay. The functionality is the same.
These relays are included in our control panel kits.
