Technical description: A-3785M series automatic circuit breakers with thermal and electromagnetic releasers, designed for maximum current protection of electrical installations and cables during overloads and short circuits in electrical circuits of direct and alternating current frequency 50 and 400 Hz, as well as for infrequent operational switching on and off these chains.

Switches A 3785M TU16-641.032-85 are designed to be installed on ships with an unlimited navigation area and can be operated in the following conditions:

a) ambient air pressure in the range of 8,000 to 16,000 mm water column;

b) ambient temperature from minus 40ºС (without dew and frost loss at temperatures from minus 40ºС to 5ºС) to 50ºС.

Sometimes it is allowed (5-7 times over the entire service life of the switch) temperature rise to 60 ºС for a time of about 2 hours;

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

g) the installation location of the switch - protected from ingress of water, oil, emulsion, etc .;

e) environment - non-explosive, not containing 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 switch and leads to aging of the insulation.

The mass of the A3781M is 8.1 kg.
