Thermal Overload Relay with High Breaking Capacity

1.Application:JRS4-d range thermal overload relay is used in AC 50Hz (or 60Hz); rated voltage is up to 660V, for protecting AC motor against overload or phase-breaking.Product feature △ Delta bimetallic strip; △ three phase; △ trip level "10"; △ with setting current regulating device; △ with ambient air temperature compensation; △ with phase failure protection; △ manual and automatic reset; △ with trip indication; △ the auxiliary contact is a normally open contact and a normally closed contact separated electrically; △ there is a normally closed contact breaking button; △ There is a mechanism detection button.Applied environment △ Ambient temperature:-5ºC-+40ºC; △ Air condition:be able to bear the influence of moisture in the air,salt fog,mould,humid air on the sea; △ Tilt and vibration:all direction should low than 22.5ºC; △ Vibration:It can be mounted on devices with 2-13.2Hz frequency,±1mm anplitude,13.2-80Hz frequency and ±7m/s accelerated speed. △Power voltage and frequency changes:steady-state voltage area is+6%- -10% of rated voltage,steady-state frequency change area is±5% of rated frequency; △The inclined angle between the mounting surface and vertical surfaceno more than 5 °,located on the place of non-sensible compact and vibration.2.Technical ParameterModel Name protection relayStandard IEC60947-4-1Setting current multiple 1.05, 1.2, 1.5, 7.2Rated current In(A) 25 36 93AmpRated voltage Un(V) 230V 240V 380VFrequency of coil 50Hz, 60Hz, 50/60HzNumber of auxiliary contact 10 /01 /11Protection grade IP20Pollution grade 33.Main parameterTypeParameterJRS4-09d-25dJRS4-32dJRS4-40d-80dJRS4-140dRated Insulation voltage Ui V690-5-40Ambient temperature(ºC)≤2000ElevationRelative humidity not exceeding 50% at the ambient temperature 40ºC humidity up to 90% at the ambient temperature 20ºCEnvironment690StandardIEC60947-4 EN60947-4Pollution gradeGrade 3Our frame protectionIP10Connect minimum load of attached circle24V 100mALead No.Of main circuit connect terminalSolft wire(mm2)41016-Hard wire(mm2)6162550root22114.We commit:5.Shipping:  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
