Dold IL9176.12 3AC50/60HZ 400/230V Safety relay, Part N: 0059134

The undervoltage relay IL 9176 of the VARIMETER series monitors 3-phase alternative current mains. The measurement is very simple and without extensive wiring, as no separate auxiliary supply is necessary. With the help of the test button on the front of the device, a fault is simulated and the relay contacts de-energized.
