LV motor control center draw-out switchgear

General:

Cabinet is divided into horizontal bus area, vertical bus area, cable area and equipment installation area and other four isolated areas, the functional unit is installed in their own small room, when any functional unit accident, will not affect the other units, to prevent the expansion of the accident. This product conforms to JB/T9661.GB7251 standard. The product adopts the IP40 protection level specified by IEC114, when all doors and protection panels are closed, or when the door is opened and the functional unit is removed from the position, the corresponding protection level can be reached, so as to ensure personal safety. The product is equipped with a perfect and reliable grounding system and protection circuit, all functional units can break the short circuit current according to the specified performance requirements, and the incoming line unit has three protection characteristics. Therefore, the reliability of power supply and the safety of equipment and systems can be ensured. All functional units can be connected with PC wire board (programmable controller) or microprocessor through the interface, as the execution unit of the automatic control system, according to user needs can also provide other content of the functional unit and function combination, the product is suitable for AC 380V, frequency 50Hz circuit.

Service Environment

• Ambient air temperature shall not be higher than +40 ° C, not lower than -5 ° C, the average temperature within 24 hours shall not be higher than +35 ° C, if exceeding, it shall be operated at reduced capacity according to the actual situation;

• Indoor use: The altitude of the use place shall not exceed 2000m

• When the relative temperature of the surrounding air is +40℃, it is not more than 50%, and a larger relative temperature is allowed at a lower temperature, such as 90% at +20℃, which should be taken into account that the effect of condensation may occur accidentally due to the change in temperature;

• The inclination of the vertical plane when the device is installed does not exceed 5℃, and the whole group of cabinets is relatively flat (in line with GBJ232-82 standard);

• The device shall be installed in a place without severe vibration and shock and insufficient to cause undue corrosion of electrical components;

• Users have special requirements can be negotiated with the manufacturer to solve

• Key Feature

• The horizontal bus has two types: single bus segment and unsegmented

• The motor control circuit has short circuit instantaneous, overload, undervoltage release and phase break protection

• The AC contact in each functional unit adopts silent operation, which has the function of energy saving
