Two Panel Switchboard –100A 400/650V AC 3ph 4 Wire – Network Rail No PA05/02022

This comprises a 2 panel changeover switchboard to Network Rail specification NR/SP/ELP/21026, and is intended to maximise the reliability of the supply by using automatic selection to choose between two supplies. The equipment comprises two incoming 400V-440V 100A AC supply circuits. Each consists of an incoming Switch Disconnector followed by a 3 pole contactor and an isolating Switch Disconnector. The outputs from the isolating Switch Disconnectors feed a bus and this is sectioned with a pole bus isolating Switch Disconnector. The bus feeds the four outgoing supply circuits, two via 4 pole Switch Fuses and two via Switch Fuses.

Associated equipment includes a kWh meter, an analogue voltage transducer, phase loss relays and a synchronisation relay.
