LRD thermal Overload Relay
Applications
This series of thermal relay can be used in the circuit of 50Hz or 60Hz, rated insulation volt
age 660V, 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 pluged in KLC1-
D series AC contactor. It is the most advanced thermal relay in the nineties in the world.
