3-Phase electrical network monitoring device
With the ENS31 a VDE0126-compliant 3-phase electricity supply can be connected to the grid.
For installations until 30 kVA the device can replace the electric utilityÂ´s anytime-accessible switchboard with isolating function.
The ENS31 controls two separated contactors. The switching capacity depends on the size of the contactors.
For installations with an anytime-accessible switchboard already installed, the ENS31 can be used as 3-phase voltage and frequency monitor. In this case is required only one contactor.
