GCK series motor control center is mainly composed of some combined motor control units and other functional units.These units are mounted in a closed metal cabinet in an overlapping manner above and below.Use the horizontal bus set above the cabinet to connect each cabinet together, and the functional units of the same cabinet are in parallel on the vertical bus.The cabinet body is divided into four mutually isolated areas such as horizontal bus area, vertical bus area, cable area and equipment installation area. The functional units are installed in their respective small rooms. When any one functional unit has an accident, it will not affect other units to prevent the expansion of the accident.
This product conforms to the standard of JB tin 9661-1999.This product USES the IP40 protection grade that IEC114 sets, when all doors and guard plate are closed, or when the door is opened and the function unit is moved out of position, all can reach the corresponding protection grade, so as to ensure personal safety.
The product is equipped with reliable grounding system and protection circuit, and all functional units can break the short circuit current according to the specified performance requirements.The incoming line element has three protection features.Therefore, the reliability of power supply and the safety of equipment and system can be guaranteed.
All functional units can be connected with PC cable board (programmable controller) or microprocessor through the interface, which can be used as the execution unit of the automatic control system. According to the needs of users, functional units and function combinations of other contents can also be provided. This product is suitable for ac 380V and 50Hz circuits.
Key electrical properties comply with IEC standards of the international electrical commission and NEMA standards of the electrical manufacturers association of America.
Delta each cabinet can separate main and auxiliary circuit isolation transformer, auxiliary circuit operating power supply for 50Hz, 220V;The signal power supply is 50Hz and 6Va
Delta by the main switch with three sections (instant, short delay and overload) protection, for and the next level of the main switch (with instantaneous and overload two sections of protection) with the cancellation of an instant section, to avoid tripping.And has the self - technology, no self - throwing and switching devices for selection.
Horizontal bus with single bus section and not section two, when the use of single bus section, bus switch also has self - cast, no self - cast and switching devices.
Delta motor control circuit has short circuit instantaneous, overload, under voltage release and break bale protection.
The communication contact in each functional unit operates silently and has energy saving function.At the same time, there is a delay (greater than 0.3s, less than 0.5s) release when the power supply disappears.Therefore, if no motor is installed, the respective starting relay can be restored within 0.3s (reclosing or standby power source time is less than 0.3s) to ensure the motor to continue running.
Delta feeder main switch with instantaneous and overload protection, when the user needs, can be installed leakage protection.
Delta lighting and household electrical circuit main switch with instantaneous, overload and leakage protection, this circuit especially in the electric drill, portable grinder and other mobile electrical power supply.
The current circuit contains ammeter, active and reactive watt-hour meter.Ammeter and ammeter can be installed or not in 250A or above feeding circuit.Other circuits larger than 37kW or 60A are fitted with ammeters.A light and alarm device can be installed in case of accident.
