1 / 1 page ARRE X SOCKET ELEMENT LIGHTING ARRESTERS FOR 3-WIRE SENSORS MODEL SK-312 TYPICAL APPLICATIONS COMMOM SPECIFICATIONS INSTALLATION ¡¤ Three-Wire Sensors or transmitter for instance Potentiometer/Resistance Temperature Construction: plug-in Housing material: plastic (black) Operating temperature: -10 to +60¡É Operating humidity: 90%RH(non-condensing) Mounting: WALL or DIN rail Size: W28.5X H71X 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.
