The wiring diagram of the NSX 100 3P breaker with MicroLogic 5.2E in single phase without breaking neutral and with the ENVT connection of the MicroLogic is as follows:

Please note the following:

• You can connect the live phase to any of the poles - i.e. Pole 1 (as in the diagram above), Pole 2 or Pole 3 (there is no specific benefit for using Pole 1 specifically, it is up to you).
• Regarding the ENVT connection, the neutral needs to be wired to the bottom of the two unused poles to ensure the micrologic operates correctly and avoids phantom measurements.

The wiring diagram of the NSX 100 3P breaker with MicroLogic 5.2E in single phase without breaking neutral and without the ENVT connection of the MicroLogic is as follows:

Please note. In this configuration, without the ENVT connection to the MicroLogic, the readings from the MicroLogic will not be accurate but the breaker will still trip correctly on thermal or instantaneous overcurrent situations.

• You can connect the live phase to any of the poles - i.e. Pole 1 (as in the diagram above), Pole 2 or Pole 3 (there is no specific benefit for using Pole 1 specifically, it is up to you).
• The unused poles remain disconnected at the bottom and top
