QM1 Thermo-magnetic molded case circuit breaker

description

Ambient and Installation Conditions

● Altitude up to 2000m;
● Ambient medium temperature should be within -5℃ to +40℃ (+45℃ for marine products);
● It can withstand the effect of damp air;
● It can withstand the effect of moulds;
● It can withstand the effect of nuclear radiation;
● The max inclination is 22.5℃.
● It still can work reliably when the ship subjects to normal vibration;
● It can still work reliably if the product subjects to the earthquake (4g).
● Places where the surrounding medium is free from explosion danger, and far away from gas or conductive dust that would erode the metal or destroy the insulation;
● Keep away from rain or snow.
