The motor relay SE 939 is a static motor relay that can be used for the protection of standard JEM-1357 three-phase induction motor. It has the function of arbitrarily combining overload, phase loss, reverse phase and other protection elements. It is easy to check the fault through the action element LED. It can adjust a wide range of current and time without starting the motor to prevent reverse rotation.
This manual covers safety precautions, wiring diagrams, and functional description of the Omron SE motor relay. It explains the relay's LED indicator, contact ratings, and installation requirements.
Detailed test procedures, timing specifications, and maintenance guidelines are included to help users verify proper operation and perform routine service on the relay. This manual is written in Chinese.
