PTW5S series air circuit breaker
Summary
PTW5S series air circuit breaker used in AC 50Hz, rated insulation voltage 1000V, rated working voltage AC380V (400V), Ac500V (690V), rated working current of 630 ~ 6300A distribution network, used to distribute electric energy and protect circuit and power supply equipment from overload, under voltage, short circuit and single-phase to ground fault etc. harm; the circuit breaker with modularized structure, intelligent too current protection function, selective protection of high precision, strong reliability, zero fly arc distance characteristics; circuit breaker with standard gb14048.2, IEC/EN60947-2.
Product features
1 drawer seat with "connection", "test", "separation" three working positions;
2. Contact system, the circuit breaker by gear contact system, in different parts of the same contact, the contact unit with the function of main contact and arc contact; using new high arc contact material, make the contact in breaking short circuit current will not cause overheating caused by too high temperature rise; contact system with multiple parallel, to reduce the repulsion force and improve the contact system of electric stability;
3. The arc extinguishing system, each pole are provided with an arc quenching chamber, and its role is to separate the electrode, and are mutually insulated, separated from the circuit breaker of the other part and an operating personnel; arc quenching chamber is arranged in a circuit breaker insulation base, increasing the mechanical strength of the arc chamber wall, not in breaking short-circuit high current burst;
4. Operating mechanism, is located in the front of the breaker, using free trip of five bar mechanism and is designed to forms of energy storage; when in use, institutions in the total pre storage location, as long as the circuit breaker received a switching command can be immediately closed; pre stored energy release can be used to manually release energy button and release electromagnet to complete, by the electric operating mechanism (both manual and function);
5 more accurate protection function.
Operating conditions and installation conditions
The air temperature is around 1 DEG C 5 40, average value and not exceeding 24h 35 C (except special order);
2 the installation location of the altitude is not more than 2000m;
3. The location of the installation of air relative humidity in the ambient air temperature is 40 DEG C + does not exceed 50%; allowing a higher under lower temperature relative humidity, the wet monthly average minimum temperature is not more than 25 DEG C +, the month of the monthly average maximum relative humidity does not exceed 90%, due to the temperature change in the product occur condensation measures must be taken.
4 pollution level is 3;
5 the use of the category is B;
6. A circuit breaker main circuit and under voltage tripping coil, power transformer primary coil installation category IV, the rest of the auxiliary circuit, a control circuit are arranged for the class III;
7 the circuit breaker shall be installed in accordance with the specification of the company, the vertical inclination of the circuit breaker shall not exceed 5;
8. The circuit breaker installed in the cabinet body compartment, and the installation of door frames, door grade IP40; installation of door frames and transparent sealed cover, protection class is IP54.
