The G3NA series of solid state relays are used to control large resistance heaters in conjunction with temperature controllers. Solid state relays are SPST, normally open switching devices with no moving parts, capable of millions of hours of operation. By applying a control signal, an SSR switches ON the AC (or DC) load current, just as the moving contacts do on a mechanical relay. Three-phase loads can be controlled using 2 or 3 SSR’s. Use 3 SSR's for Y or star 3-phase loads using a neutral line. Two SSR’s will control "delta" loads with no neutral line. Three solid state relays are also used when there is no neutral load to provide redundancy and extra assurance of control.
"Switching" takes place at the zero voltage crossover point of the alternating current cycle. Because of this, no appreciable electrical noise is generated, making SSR's ideal for environments where there are apparatuses susceptible to RFI.
