WIRING DIAGRAM AND CHARACTERISTIC CURVES JT3FD SUBMINIATURE HIGH Unit: POWER RELAYmm CHARACTERISTIC CURVES Percentage of nominal coil voltage 1.Coil operaying voltage range 200 Umax. (Standard) 180 1)There should be no contact load applied when maximum continuous operation voltage is applied on coil. 2)The operating voltage is connected with coilpre-energiced time and voltage.After pre-energized,the operating voltage will increase. 3) The maximum allowable coil temperature is 180℃. For the coil temperature rise which is measured by resistance is average value,we recommend the coil temperature...

CHARACTERISTIC CURVES 1) The contact load is resistive. 2) The load and electrical endurance tests are made according to “CONTACT DATA”parameters’ table. If actual load voltage,current,operate frequency is different from “CONTACT DATA”table,please arrange corresponding tests for confirmation. 3) This chart takes 70A load as example. 3.Ambient temperature curve of the electrical endurance test Ambient temp. curve (one cycle) Temperature (°C) 1) The minimum temperature is -40℃. 2) The maximum temperature is 125℃.
