Product Description
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 surface
no more than 5 °,located on the place of non-sensible compact and vibration.
no more than 5 °,located on the place of non-sensible compact and vibration.
