Technical Description: A 3772M circuit breakers (with electromagnetic tripping devices) are designed for maximum current protection of electrical installations and cables during short circuits in DC and AC circuits with frequencies of 50 and 400 Hz, as well as for infrequent operational switching on and off of these circuits. The A-3772M TU16-641.032-85 switches are designed for installation on ships with an unlimited navigation area and can be operated under the following conditions:
a) ambient air pressure ranging from 8,000 to 16,000 mm H2O;
b) ambient air temperature from minus 40ºC (without dew or frost at temperatures from minus 40ºC to 5ºC) to 50ºC. Occasional increases in temperature to 60ºC for approximately 2 hours (5-7 times during the switch's service life) are permissible;
c) relative ambient air humidity no more than 98% at a temperature of 40ºC;
d) switch installation location - protected from water, oil, emulsion, etc.;
d) The environment is non-explosive and does not contain dust (including conductive dust) in quantities that could impair the operation of the circuit breaker, or aggressive gases or vapors in concentrations that could damage metals and insulation;
e) No direct exposure to solar or penetrating radiation that could disrupt the circuit breaker's thermal balance and cause insulation aging.
