Descirption:

GDM101 series moulded case circuit breaker(hereinafter referred to as circuit breaker)is mainly used to distribute power and prevent circuit and power supply equipment from damage due tp fault like overload,short circuit and under voltage in AC 50Hz distribution network circuit of infrequent operation with rated operation voltage up to 380V and rated current up to 600A.
The product in accordance with standard of GB1.4048.2

Normal service condition:

1.Ambient air temperature
1.1The ambient air temperature shall not exceed+40ºC;
1.2The average value shall not exceed+35ºC within 24hours;
1.3The ambient air temperature shall not be less than -5ºC
2.The attitude of the installation site shall not exceed 2000m;
3.The pollution level is class 3
4.The inclination to vertical surface shall not exceed 5°
5.Installation environment condition
5.1 In place of no obvious shall and impact
5.2 In medium of no explosion danger and no sufficient gas and dust that may corrod metal and destroy insulation(including conductive dust)
5.3In place of no snow and rain
6.Atmosphere condition:
The relative humidity of atmosphere shall not exceed 50%at highest temperature of +40ºC,and it can be higher at a lower temperature,when the average lowest temperature in the wettest month doesn't exceed 25ºC is 90%,condensation on product surface due to temperature change must be taken into account

Main technical parameter

1.Inverse time breaking characteristic when each pole is powered on at the same time,over current release breaks under overload condition at +40ºC ambient air temperature(see folloing table)
