Depot CP – 2 Pole Exam Road Depot Contactor Panel - 500A or 630A 630V DC

 

Application – on load

The 630V DC is then fed directly from the Contactor to the Road Shore Supply for the Overhead Switchable Trolleys (8800290) OR to the Lifting Shed Power Pedestals (8800291).Used on London Underground

 

The 630V DC is fed to the 2 pole contactor via:

4 pole Isolating & Bonding Disconnector, which has interlocks for Maintenance and Secure Isolations. These prevent contactor operation and the 630V DC supply when maintenance is being performed.

The Contactor provides signals to the Overhead Status Indicators OSI and the Mimic Panel in the DDM Office.

When the Disconnector is moved to the Earthed position the outgoing supplies to the Examination or Lifting Sheds are earthed and can be locked, making them safe for maintenance.
