JRS2(3UA5)Thermal Overload Relay
Scope of application
JRS2 series thermal overload relay is suitable for AC 50Hz, rated working voltage up to 660V in main
Circuit and in the power system of rated current up to 0.1-630A as a three-phase AC motor overload
And phase failure protection.
Structure features
Full range of products has the function of overloading and phase failure protection. The setting current
Can be adjusted, and the setting current of most heating elements is overlapping sequence in cross-cascade so that it is easy for users to choose. In the temperature range of -5 ° C to 55 ° C, there is air
Temperature compensation. The test button of breaking NC contacts has action
Instruction and automatic tripping indication. Can carry with a guard to prevent electric shock. It also has
Stand-alone installation, the installation of inserting contactors, rail installation and many others.
