Application

  • LR2-D series of thermal relay can be used in the circuit of 50Hz or 60Hz,rated insulation voltage 660V,rated current 0.1 ~ 0.93A for protecting the phase break when the electric motor is overload.
  • The relay has different mechanism and temperature compensation & can be pluged in LC1-D series AC contact. It is the most advanced thermal relay in the ninneties in the world.
