A3700P Circuit Breakers

The manufacturer introduces A3700P circuit breakers designed to conduct current in normal mode and disconnect current during overloads and short circuits in electrical circuits with a rated voltage up to 440V DC, up to 660V AC frequency 50Hz and up to 400V AC frequency 400Hz, as well as for operational communications these chains. The A3700P automatic switches of new producers of GP KHEMZ, VIRA, LTD, NPP RIMK are made only in Ukraine. Certified.

Switches A 3700P designed for operation in mobile and stationary electrical installations in the following conditions:

a) height above sea level up to 4000 m;

b) ambient temperature from minus 50 ºС (without dew and frost) to 60 ºС, design temperature 40 ºС. It is allowed to raise the ambient air temperature to 65ºС within 2 to 4 hours;

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

d) environment - non-explosive, does not contain dust (including that which is conductive) in a quantity that disrupts the operation of the switch, aggressive gases and vapors in concentrations that destroy metals and insulation. Air dustiness is not more than 2.5 g / m3;

e) the installation place of the A-3700P automatic switch is protected from ingress of water, oil, emulsion, etc.;

e) the absence of direct exposure to sunlight and other energy that violates the thermal balance of the switch and leads to aging of the switches;

g) when exposed to mechanical environmental factors in places where the switch is attached;

vibration loads with frequency up to 80 Hz and acceleration 6g;

repeated impact loads with acceleration up to 15g and pulse duration of 5 - 10 ms;

single-load shock loads with an acceleration of 12g and a pulse duration of 1–5 ms;

i) the working position of the switch in space is on the vertical plane with the inscription "I" up, right and left. Deviations are allowed in any direction from the working position to 30º when the switch is installed with the inscription "I" up to 5º - the inscription "I" to the right and to the left
