Circuit breakers A3771M

Manufacturer RPE RIMK offers to your attention the A3771M circuit breakers for voltage supply 320DC, 380V - 660V AC 50Hz and 400Hz in Ukraine. Always available any standard versions of automatIC circuit breaker A-3771M 2P. The warranty on the A3771 M switches is fifteen years. Delivery to any country in the world using transport companies! А 3771М circuit breakers for 125А, 80А, 100А, 50А, 40А, 63А, 25А, 16A are assembled according to all the developed methods, by our specialists, during their work activity at the state enterprise NPO KHEMZ and scientific research institute Electroapparat of Kharkov. The quality of our series A 3700M circuit breakers is currently higher than before. Since we have improved the assembly technology, testing and calibration, pulling them up to the European level. We have a reasonable price in Ukraine and the world for new A 3771 M switches. With a union of tens of thousands of automatic switches A3771M were used in Ukraine, Kazakhstan, Moldova, Latvia, Lithuania, Estonia, Turkey, Bulgaria, South Korea as well as countries in Europe, Africa, Asia and South America.

Automatic switches A3771M series (withelectromagnetic releases) are designed for maximum current protection of electrical installations and cables during overloads and short circuits in AC and DC electric circuits of frequency 50 and 400Hz, as well as for infrequent operational switch-on and disconnection of these circuits.

Switches A3771M 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) environment - non-explosive, free of dust (including conductive) 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.
