Switches A3728SM are designed for installation on ships with unlimited navigation area and can be operated under 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 disrupts the thermal balance of the circuit breaker and leads to aging of the insulation
