Application
This series of thermal relay can be used in the circuit of 50Hz or 60Hz, rated insulation voltage 660V, rated current 0.1-93A for protecting the phase break when the electric motor is overload. The r e lay has different mechanism and temperature compensation & can be pluged in LC1-D series AC contact. It is the most advanced thermal relay in the nineties in the world.
Characteristics
