LR2 THERMAL RELAY
|
|
||||
|
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 relay has different mechanism and temperature compensation & can be plugged in LC1-D series AC contactor. At present, it is the most advanced thermal relay in the world. |
