Application- on load
The equipment comprises a Multi-Circuit Distribution Switchboard to Railtrack Plc specification, and is designed to provide distribution of a number of incoming supplies to their various load circuits.
A system is provided for recognising and identifying a blown fuse in the switchboard to facilitate rapid restoration of a supply in the event of a fuse failure.
The switchboard, pictured above, provides a power supply for signalling, where the continuity of the supply is critical.
