Drawer Type MCC Enclosure is used for places that require energy continuity. Drawer Type Electrical Panels have a separate drawer for all outputs in the system. Control, protection, communication and measuring parts of the outputs are mounted inside the drawer. Power and control connections are connected to the output cables with sockets. Thus, it is possible to replace the drawer of the malfunctioning output unit with a spare one.
What is a Drawer Type MCC Enclosure?
Drawer Type MCC Enclosure is also known as Withdrawable Type MCC. These panels enable maintenance and replacement operations to be carried out without stopping the system in electrical panels where the energy should not be cut off. Drawer cabinets are widely preferred in motor control centers (MCC).
MCC stands for Motion Control Chart. Its Turkish equivalent is motion control systems programming technique. Engine control panels contain engine control and command devices.
The withdrawable type MCC panel is mostly used in industries such as chemical, paper, cement industry and water treatment plants, where the fault must be rectified without stopping the system in case of failure. It is simpler to repair the drawer type electrical panels and to make the desired changes in these panels compared to the fixed type panels.
Drawer modules can be inserted and removed in drawer panels. The cabling method in classical connection systems is not available in drawer cabinets. All drawer units are connected to the electrical panel with electrical connections for power and control with energy sockets. The cables coming from the field are connected with sockets.
What are the Advantages of Using Drawer Type Enclosures?
- Drawer type panels are frequently used.
- The power circuit can produce up to 630 amps with full drawers.
- It is possible to change the unit without interrupting the energy in the electrical panel.
- Maintenance and repair of the unit is possible without any power cut.
- It is possible to renew power and power without cutting off the energy in the electrical panel.
- Drawer modules can be easily removed.
- Drawer modules can be simply positioned for testing.
- It has a high security switching system.
How to Use Drawer Type MCC Enclosure?
Electrical energy is taken from the busbar in the main table through the contacts on the drawer. It is transmitted to the output terminals. Control and locking contacts connect with mobile control terminals. There is the possibility of locking when the drawers are in the test, working and repair position. When the drawer is not fully seated during operation, the limit switch, which manages the coil circuit, prevents and warns the contactor from working.
It has a high-level security switching system. Even in the event of a short circuit that may occur in the electrical panel, it can work up to 630A with its force and contacts. There is no need to shut down the system in case of any renewal or malfunction that may occur in the system. Drawer modules can be quickly replaced or added.
