Depot CRCP – 2 Pole Depot Cleaning Road Contactor Panel - 500A or 630A 750V DC

Application – on load

These 630V DC bus bars are connected into a suite of Contactor Panels and the incoming supply to these bus bars is fed by a Shed Board Isolator (8800287). The 630V DC is then fed directly from the Contactor to the Cleaning Road conductor rails. 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 Cleaning Road Overhead Status Indicators COSI and the Mimic Panel in the DDM Office.

When the Disconnector is moved to the earthed position the outgoing supplies to the Cleaning Road Conductor Rails earthed and can be locked, making them safe for maintenance.

Control of the contactor supply can be done at a remote control panel at the end of the road or at local control buttons at the contactor in the Switch room.

The contactor panel is interlocked with the Depot Fire Alarm, Sump Pumps and Flood Sensors Used by London Underground
