100A 6300A 380V 660V 50Hz ACB Air Circuit Breaker MCCB Performance Heat Resistant


ZMW50-1000 conventional circuit breaker (hereinafter call “breaker”) is suitably used in the distribution circuit of AC 50Hz, rated voltage 400V, rated current 200 ~1000A, to distribute electric power and protect circuit and equipment from overloading, short circuit, under-voltage, single phase earthing, residual current faults. At normal working conditions the breaker can be used to transfer the distribution lines or start the motor non-frequently. The breaker provides the intelligent protection function and high precise selective protection, improve the reliability of power supply, and prevent unnecessarily cutting off power supply. The breaker has isolation function.

Normal Working Condition

Temperature: -5℃-+40℃, the average can't more than+35℃ with in 24 hours.

Altitude: not higher than 2000m for the installation site.

When the ambient air temperature is +40℃, the relative humidity of the air shall not be higher than 50%; a higher relative humidity is allowed at a lower temperature; special measures shall be taken for the condensation occasionally produced due to temperature change.

Degree of Pollution: III

Use Category: B type

Installation conditions: the mounting inclined angel shall not more the +5°
