Descrizione del prodotto

The overcurrent and undercurrent relays of the VARIMETER series are suitable for monitoring currents in three-phase and alternating current networks. If the current exceeds or falls below the switching point, the relays change state after the time has elapsed. The relays can be used universally thanks to the adjustable switching point. The adjustable time delay can be used to take current peaks into account or to suppress them if necessary. Operational readiness and over- or undercurrent are indicated by an LED.
