Abstract

PURPOSE: To increase the reliability by avoiding the malfunction due to the types of wiring systems, through the fixed wiring from the zero phase current transformer to the switching circuit section.
CONSTITUTION: The zero phase current transformer 1 contained in the case 2 provided the secondary output terminals 3. Further, the switching circuit section 4 is operated with the secondary output of the current transformer 1, and the current transformer 1 and the circuit 4 are directly fitted to the wiring board 5. The wiring 6 connecting between the terminals 3 and the circuit 4 is formed with a metal plate of a given shape, it is fixed on the wiring board 5, to plug in the terminals 3. Since the location and form of the wiring 6 is determined, the occurrence caused due to the dispersion in the wiring length and location for each product is avoided to increase the reliability.
