Lrd Thermal Overload Relay Motor Protection

Excellent Material Good Quality contactor industrial,contactor 110v dc 100 amp

APPLICATION

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This series of thermal relay can be used in the circuit of 50Hz or 60Hz,rated insulation

voltage660V,rated current 0.1-96A for protecting the phase break when the electric motor is

overload.The relay has different mechanism and temperature compensation & can be

plugged in LC1-D series AC contactor.It is the most advanced thermal relay in the nineties in the world.
