Low Tension Control Panel for DC distribution are installed in Traction Substations for 110V DC distribution. Two incoming circuits from the dc output terminals of the battery chargers are connected through a double pole change over switch to a bus bar housed inside the panel. The Lead-Acid battery of 110 V will be directly connected to these bus bars. LED lamps are provided for each of the outgoing circuits to indicate the availability of supply and also for bus bar supply indication. All the switches and MCBs are rated for operation on 110V DC.
The Panel Board is of Single front type, Cubicle Design, Uniform depth, Compartmentalized, Dust & vermin Proof fabricated by 1.6mm thick CRCA Sheet. The bus bars inside the panel are centrally located. The MCBs are mounted below the bus bars and so provided inside the panel that their operating levers/ knobs cannot be accessed from outside unless the panel cover is opened.
