Product Description
GCK series electromotor control center is mainly composed with some combined control unit and other function unit. These units are installed in a close metal cabinet in overlap way, every cabinet is connected with by horizontal bus bar, which is set on the top of cabinet, while the control functions function units in one cabinet are parallel connected in parallel in the vertical bus bar. The cabinet is divided into four isolated areas; They are horizontal bus area, vertical bus bar area, cable areas and equipment installation areas. Every function unit is installed in itself room, when accident occur in any one function unit, it can't affect other units, and can prevent expansion of the accident.
All the function units can be connected with PC line board (PLC) or microcomputer through interface access. They are used for performance units of automatic control system. We can also provide other function unit and combination according to customers needs.
This switchgear is suitable for power circuit of 380V A. C. And 50Hz.
Main features:
1. The main electrical performance conforms to the standards of IEC and NEMA.
2. Every cabinet's main and auxiliary circuits can be divided by isolation transformer. Auxiliary circuit's operation power supply is 50Hz, 220V, while the signal power supply is 50Hz, 6V.
3. The parasite power main switch electricity main switch has three periods of protection of instant, short delay and overload, it works with the next level main switch, which has two periods of protection of instant and overload, can avoid override trip. Automatic switch, manual switch and switching device can be selected for users.
4. Horizontal bus bar has two types: Single bus bar with section and single bus bar without section. When single bus bar with section is used, the bus coupler switch also has automatic switch, manual switch and switching device.
5. When motor controls the circuit, it has protections of short circuit instant, overload, under-voltage release and phase loss.
6. When the AC contactor of every function unit running silent, it can save energy. Meanwhile, when the power supply is cut off, it has property of delayed release (0.3s-0.5s). So it can recover the power supply within 0.3s without starting relay, to ensure the motor continues to run.
7. Main switch of electric power supply circuit has instantaneous and overload protection, if customer needs, leakage protection can be added too.
8. Main circuit of lighting and household appliances have protections of instantaneous, overload and leakage, so the circuit is suitable for supplying power for mobile electrical appliances such as electric drill, hand grinder etc.
