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 salt fog or oil mist;
  • 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.

Features

  • Circuit breaker can be equipped with undervoltage release, shunt release, auxiliary contacts, alarm contacts, electric operating mechanism, rotary operating handle and other accessories.
  • Circuit breaker has protection functions of overload long delay, short-circuit short delay and short-circuit instantaneous protection, the user can set the required protection characteristics (user only needs to operate the DIP switch for settings of protection function parameters).
  • Circuit breaker has ground fault and thermal analog protection functions, pre-alarm indication over-current indication, load current indication, digital current analysis technology, and it can achieve a higher level of protection.
