Mô tả/ Product description
The voltage relay BA 9054 of the VARIMETER series monitors single phase DC or AC voltage systems (with 1 Measuring range for AC and DC). The adjustment is made via potentiometers on the front of the device. Early recognition and preventive maintenance avoid interruptions of electrical plants and provides a higher operational and plant safety.
