Circuit system diagram how the circuit breaker said
Most of the power applications are used in conjunction with circuit breakers and disconnectors, with the circuit breaker, load (fault) current, with the isolation switch to form a clear point
the current does not exceed 5A of the no-load lines, in order to use the isolation switch for direct operation.
Therefore, the disconnector can only be in the circuit has been broken when the circuit breaker to operate, is strictly prohibited with the load operation
so as to avoid serious equipment and personal accidents. Only the voltage transformer, arrester, the excitation current does not exceed 2A no-load transformer
