特徴とする中性線欠相保護装置付漏電遮断器。 For cutting off the power of the single-phase three-wire distribution line by triggering a silicon-controlled rectifying element by the output from the secondary coil of a zero-phase current transformer whose primary coil is the load circuit of the single-phase three-wire distribution line. In an earth leakage breaker that turns on a trip coil to cut off the power supply, a voltage dividing resistor is connected between both voltage lines and the neutral line of the single-phase three-wire distribution line via a center-tap type full-wave rectifier circuit, and A smoothing/delay circuit consisting of a parallel circuit of a resistor and a capacitor is connected to the piezoresistor via a backflow blocking rectifier, and the smoothing/delay circuit is connected between the smoothing/delay circuit and the gate terminal of the silicon-controlled rectifier.・Continuity occurs when the output voltage from the delay circuit exceeds a preset voltage determined by the unbalanced voltage between the load terminals of each voltage line due to a break in the neutral wire of the single-phase three-wire distribution line. An earth leakage breaker with a neutral line open phase protection device, characterized in that a trigger element is connected to turn on the silicon-controlled rectifying element.
