功能

• The protective elements (1E to 3E) conform to the optional static motor relay
• JEM-1357 static protection relay for three-phase induction motor.
• The protection element can be any combination of overloaded, out-of-phase and anti-phase (1E-3E) by the switching switch.
• Operation of the circuit and output relay can be checked by operating the test switch.
• In addition, the time adjustment of the operation time can be easily confirmed by the start display.
• An integral structure having a small occupied area in the board.
• Note. When used with an inverter, the usage conditions vary depending on the load side wiring length, inverter carrier frequency, basic frequency, and load condition.
• It is recommended to perform an operation test before use, as this may cause an error in the operation value of the overload element.
