RI-R44

RI-R44 is a device that allows the insulation monitoring to earth up to 440 VAC of networks (IT systems).

By applying a DC component measure signal between the insulated line and earth it’s possible to control the insulation resistance by detecting the generated leakage current. Configurable automatic or manual resetting.

It has a TRIP changeover contact configurable normally de-energised or energised.

The RI-R44 is also provided with a RS-485 optional interface with Modbus protocol to consent the integration in supervision systems.
