LR2 Thermal Relayy
 
Application
This series of thermal relay can be used in the circuit of 50Hz or 60Hz, rated insulation voltage 660V, rated current 0.1-93Afor protecting the phase break when the electric motor is overload.
The relay has different mechanism and temperature
compensation, and it can be plugged in LC1-D series ACC ontactor. At present, it is the most advanced thermal relay in the world.
