ENIP-2 Compact

ENIP‑2 in a metal case features compact dimensions and is used in the cells of complete 6-20 kV switchgear. It monitors voltage presence is equipped with digital inputs and relay outputs, and has two 24 V DC power inputs.

ENIP-2 is mounted on a DIN rail using the bracket supplied with the device.

In addition to the device, you can select fasteners for installation in different types of control panel cells (available on request).
