| ARREX TYPICAL APPLICATIONS Three-Wire Sensors or transmitter for instance Potentiometer/Resistance Temperature LIGHTING ARRESTERS FOR 3-WIRE SENSORS MODEL SK-312 ELEMENT COMMOM SPECIFICATIONS Construction : plug-in Housing material : plastic (black) SOCKET INSTALLATION Operating temperature : -10 to +60 E Operating humidity : 90%RH(non-condensing) Mounting : WALL or DIN rail Size : W28.5 X H71 X D78.5 Weight : 72g The Vector Lightning Arrester Model SK-312 is designed specifically for 3-wire sensors transmitter. Lightning surges damage that enters into wiring between the potentiometter/RTD and transmitter will be absorbed by the SK-312, thus will protect the potentiometer and transmitter.
