    TXDB1L-63 Residual Current Circuit Breaker improved from by DZ30LE, the internal circuit board adopts integrated circuit, the performance is more superior and reliable!
    TXDB1L-63 (DPN Vigi) (phase line + neutral line+ leakage + overvoltage) protection circuit breaker is suitable for the single-phase residential circuit of 50Hz / 60Hz, rated voltage of 230V, rated current of 63A, to protect leakage, and protect overload and short-circuit of the civil electrical circuit. The earth leakage switch can also infrequently switch on or off electrical equipment and lighting lines under normal circumstances, especially for industrial and commercial lighting distribution system. The earth leakage switch has a small size, high breaking capacity; null line and live line are cut off at the same time, and in the case of live line reversed, the electric leakage circuit breaker still able to protect against leakage. The filter in the electronic leakage over-voltage protection can prevent the misoperation tripping caused by instantaneous voltage (lighting, line interference of other equipment) and instantaneous current (such as capacitive load line).
    the electric leakage circuit breaker meets standards of GB16917.1 and others.

    Structure and working principle

    the electric leakage circuit breaker is current action electronic leakage circuit breaker. It is an integrative miniature leakage protection circuit breaker designed for single-phase circuit, has large capacity and small size, to save resources and space for the user installation.
    the electric leakage circuit breaker is mainly composed of contact, case, operating mechanism, electromagnetic system, tripping device, arc extinguishing device, zero-sequence transformer, electronic discriminating control circuit and tripping indication and other parts. The earth leakage switch has protection functions of overload, short circuit and leakage.
    The working principle of the earth leakage switch
    Overload protection: when the overload occurs, the bimetal promotes the lock, to make the circuit breaker trip to protect the circuit;
    Short-circuit protection: When the short-circuit fault occurs, the electromagnetic coils create a strong magnetic field, the core promotes the lock quickly, to make the circuit breaker trip (cut off the power supply within 0.1s) and action protection;
    Leakage protection: When leakage fault occurs in the protection circuit, current vector sum of the zero-sequence current transformer is not equal to zero, the transformer secondary output generates voltage, to make the SCR breakover, electromagnetic tripping system act, to make the trip with rod promoting circuit breaker trip, and cut off the power supply within 0.1s, which play a leakage protection.
