Product Description

DZ40LE RCBO

SCOPE OF APPLICATION

The DZ40LE RCBO 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 MCB 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 DZ40LE Residual Current 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.
