Circuit breaker A3778M

Manufacture and sale of A3778M circuit breakers for rated current 160A 380V-660V 50-400 hertz.  A 3778M circuit breakers have proven themselves well at factories in Ukraine, Bulgaria, Kazakhstan, Uzbekistan, Georgia, Algeria, Poland, Algeria, Egypt, Iraq, Lithuania, Estonia, Latvia, Poland, Armenia, and other countries in Europe, Asia and Africa.  The warranty for the A-3778M automatic circuit breaker is 15 years.  We export

Automatic switches А3778М are intended for carrying out of a current in electric circuits of direct and alternating current of frequency 50 and 400 Hz, and also for infrequent operational switching-on and switching-off of these circuits. A3778M-in fact, not an automatic switch (switch)!

Circuit breaker A3778M TU16-641.032-85 are designed for installation on ships with an unlimited area of ​​navigation and can be operated in the following conditions:

a) ambient air pressure in the range from 8000 to 16000 mm of water column;

b) ambient air temperature from minus 40ºС (without dropping of dew and frost at temperatures from minus 40ºС to 5ºС) to 50ºС. It is sometimes permissible (5-7 times for the whole service life of the switch) to raise the temperature to 60 ° C for a period of about 2 hours;

c) the relative humidity of the ambient air is not more than 98% at a temperature of 40 ° C;

d) the location of the switch - protected from water, oil, emulsion, etc .;

e) the environment is not explosive, does not contain dust (including conductive current) in an amount that disrupts the operation of the switch, aggressive gases and vapors in concentrations that destroy metals and insulation;

e) the absence of direct exposure to solar and penetrating radiation, which violates the thermal balance of the circuit breaker and leads to aging of the insulation.
