DUAL CHANNEL CIRCUIT BREAKER

The dual channel circuit breaker is designed to interrupt power to any circuit that has an
overload. Each channel of the breaker will trip at a maximum current level that is determined by
an external resistor. The range of trip values is shown in the table below.

If the breaker trips, it automatically attempts to reset 2 to 3 times per second. If the fault
is still there the breaker trips again and continues to attempt to reset. Each channel of the circuit
breaker operates completely independent of the other channel, or any additional breakers. Thus
a short in one section of the railroad will not effect operation in any other section. Any number
of dual channel circuit breakers may be used to divide the railroad up into the desired number of
circuits. The trip current of each channel of the breaker may be set to any value depending on the
expected maximum load of that circuit.
