Normal Working and Installation Conditionsr

◆The upper limit of ambient temperature should not exceed+40℃,while the lower limit of ambient temperature should not belower than-5℃; and the 24h average temperature should not exceed+35℃;
Note:
1)If the ambient temperature exceeds+40℃,the volume should be reduced.See the relevant volume reduction coefficient part of this manual;
2)Products with the upper limit of ambient air temperature not exceeding+60℃ and the lower limit not lower than-25℃ can be specially ordered;
◆Altitude:The altitude of the installation site does not exceed 2000m,and reference can be made to the high altitude volume reduction coefficient;
◆Atmospheric conditions:When the ambient air temperature is +40℃,the relative humidity of the air does not exceed 50%,and higher humidity can be allowed at lower temperature,for example,t can reach 90%at+20℃.Special measures should be adopted for condensation occasionally caused by temperature variation;
◆Pollution level:3;
◆Installtion category:The installation category of main circuit (including undervoltage trip coil is of class V;Control circuit and auxiliary circuit are of class Ⅲ;
◆Insallaion conditions:The circuit-breaker shall be installed according to the requirements of the manual,and the vertical inclination of thee circuit-breaker shall not exceed 5°;
◆Requirements of installation protection leve:IP30 and IP40(which are installed in the cabinet room with door frame and plexiglass cover);
◆Usage category.A or B.

Product Featuresr

◆The contact system is installed in the insulation chamber,and the contact system of each phase shall be the multi-channel sheet structure; The electrodynamic compensation is realized to ensure the high breaking ability of the circuit-breaker;
◆Advanced arc extinguishing system and protective cover ensure "zero flashing"and make products more safe;
◆ The circuit-breaker is closed by the energy storage mechanism,and the closing speed is fast;
◆The operating mechanism is installed in the front centre of the circuit breaker and completely separated from the main circuit,which can make each phase pole have stable and consistent contact final pressure and play an important role in ensuning the realization of temperature rise and breaking index,especially the circuit-breaker with 6300A shell frame is more important;
◆The centre operation mechanism is convenient for the centre symmetrical opening of the complete cabinet door,which improves the appearance quality of the complete cabinet;
◆With 3-pole and 4-pole;
◆ Withdrawable and fixed types;
◆Wire can be installed from the bottom,with horizontal and vertical wiring modes;
◆Intelligent controller has multiple protection functions,which can realize selective protection;For 2M,3M LCD display controlle,in addition to the current display and protection,the measurement and protection of the function such as voltage,frequency,phase sequence and power can be increasedwhich makes the functions more powerful;
2H and 3H inteligent controllers have the functions of communication networking and monitoring.Modbus,Profibus and Device-net protocols can be applied to facilitate bus integrated management Remote control,telemetry,remote communication and remote regulation could be realized;
◆Various forms of mechanical interlocking (types of lever and steel cable),withdrawable lock,door interlocking and safety-guaranteed open position lock,reaizing the locking of circuit breaker,and the whole series is universal.
