There are 6 versions of the device, depending on the type of current input: MCA PLUS II - ITF, indirect current measurement with /5A or /1A transformers. MCA PLUS II - ITF-IN, indirect current measurement with /5A or /1A transformers and an input to measure the neutral current.
The MCA PLUS II device must be installed by authorised and qualified staff. The power supply plug must be disconnected and measuring systems switched off before handling, altering the connections or replacing the device.
The flexibility of the sensor allows it to measure an alternating current irrespective of the posi- tion of the conductor. LIFASA has 2 Rogowski sensor models that can be used with the MCA PLUS II - FLEX: FLEX- MAG and FLEX-BAY.
