With very low output currents, a balancing resistor may be required for control operation.
In accordance with DVGW GW 12, it is recommended to protect the protective current device against transient overvoltages in the load and measuring circuit by using suitable surge arresters.
Technical documentation and operating instructions included.
The devices are available in:
- voltage-regulated
- current-regulated
- potential-regulated
- potential-regulated with basic power supply
