Description:
The JL-LR28 thermal overload relay is an economic electromechanical protection device for the main circuit.
The thermal overload relay offers reliable and fast protection for motors in the event of overload or phase failure. The device has trip class 10A. Further features are the temperature compensation, trip contact (NC), signal contact (NO), automatic- or manual reset selectable, trip-free mechanism, STOP- and Test function and a trip indication.
The thermal overload relay is connected directly to the block contactors. Single mounting kits are available as accessory.
Applications:
JL-LR28 Thermal Overload Relay electrical application, telecommunication, automatic control, wireless radio remote control and sound control toy application.
