Abstract
PURPOSE: To provide an inexpensive distribution line shortage protector by combining a normally exciting no-voltage open type switch with a controller having an overcurrent detector and control circuit to thus construct a cmpact and convenient switch.
CONSTITUTION: A switch 30 is always operated to close a circuit of an electrode 31 by the exciting power "ON" operation of a control circuit 42. When a shortage fault occurs at the load side, a fault current is supplied via a current transformer 3 to an overcurrent detector 23. When the fault current becomes over predetermined level, a signal is fed to the circuit 42, which has function for limiting time in response to the necessity to deenergize the coil 32 when predetermined conditions are satisfied to thereby open the electrode 31.
