63A Residual Current Operated Circuit Breaker RCB MCB Circuit Breaker
Application
ZM30LE-63 series leakage circuit breaker is suitable for the circuit of AC 50Hz, rated working voltage 230V and rated current 40A and below, to make indirect contact protection to the human being and protect the circuit against over current in buildings or other similar locations as well, also to prevent fire accident caused by continuous ground fault current due to the damage of over-current protection equipment. In addition, the leakage circuit breaker with over voltage protection can prevent the over voltage caused by fault of power grid.This series of products is more and more used for stand-by protection against ground fault and electric shocks by direct contact and indirect contact in the low voltage distribution system. The products are in conformity with such standards as GB 16917 and IEC61009.

External And Installation Size
Normal operating conditions
1.Ambient air temperature: -5°C~+40°C, the mean value is no greater than +35°C within 24 hours . Note: If the upper limit is higher than +40°C or lower limit lower than -5°C in work, discussions shall be made between the user and the manufacturer.
2.Altitude: not higher than 2000m for the installation site.
3.When the ambient air temperature is +40°C, the relative humidity of the air shall not be higher than 50%; a higher relative humidity is allowed at a lower temperature; for example, for the wettest month, the maximum relative humidity averaged shall be 90% while the lowest temperature averaged in that month +20°C, and special measures shall be taken for the condensation occasionally produced due to temperature change.
4.Class of Pollution: 2
5.Installation category: II, III
6.The ambient air is not significantly polluted by dust, smoke, corrosive and/or flammable gases, vapours or salt.
