Circuit breaker A3777M

Automatic switches А3777М 150A, 80A, 63A, 40A, 25A are designed for conducting current in AC and DC electric circuits of frequency 50 and 400Hz, as well as for infrequent operative switching on and off of these circuits. A3777M- not a circuit breaker in fact! Export.  EAC Certificate of Conformity No. EAEU KG417 / 033.UA02.00261 for the entire series of A3700 circuit breakers!  The A 3777M switches have shown themselves to be excellent at enterprises in Ukraine, Lithuania, Estonia, Tajikistan, Kyrgyzstan, Turkmenistan, Azerbaijan, Latvia, Poland, Bulgaria, Kazakhstan, Uzbekistan, Turkey, Poland, Qatar, United Arab Emirates, Georgia, Armenia and others.  countries in Europe, Asia and Africa. The warranty for the A-3777M is 15 years!

Circuit breaker A3777M TU16-641.032-85 are designed for installation on ships with unlimited navigation area 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.
