RESISTOR INSTALLED IN NEIGHBORHOOD OF DISTRIBUTION CIRCUIT BREAKER PREPARED IN ELECTRICAL DISTRIBUTION BOX

摘要

The present invention relates to a resistor installed in the neighborhood of a distribution circuit breaker prepared in an electrical distribution box, and more particularly, to a resistor installed in the neighborhood of a distribution circuit breaker prepared in an electrical distribution box, capable of protecting the circuit breaker by a trip operation to quickly separate a moving contact from a fixed contact in the circuit breaker by enabling the resistor prepared in the neighborhood of one phase on a circuit breaker load side to suppress and limit a current below a rated breaking current of the circuit breaker if a line short or a ground short is generated on a load side. To this end, the present invention includes the resistor (40) to protect the distribution circuit breaker (30) by making a current flow below the rated breaking current of the distribution circuit breaker (30) if the line short or the ground short is generated in a load side line part (50), in the neighborhood of one phase of the load side (30-2) of the distribution circuit breaker prepared in the electrical distribution box.;COPYRIGHT KIPO 2017
