Thermal Relays Series
HR2-D Thermal Relay
Application 
   This series of thermal relay can be used in the circuit of 50HZ or 60HZ,rated insulation voltag 660V,rated current 0.1-93A for protecting the phase break when the electric motor is overload.
   The relay has different mechanism and temperature compensation &
can be pluged in HC-D series AC contact.It is the most advanced thermal relay in the nineties in the world.
