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.
