Functions of the power supply inputs of the 3KC3 transfer switching equipment

Inputs 101/102 and 201/202

The 3KC3 transfer switching equipment comes with two independent power supply inputs, 101/102 and 201/202.

Use of the dual power system (DPS) accessory offers complete reliability, as it makes it possible to switch to all three positions when either source I or source II is available. Alternatively, an external uninterrupted voltage supply can be connected to the network.
