MC-MN-Series metal clad and withdrawable panels are designed & manufactured by MNCO company, according to IEC-60298 standards. This series of MV panels meets all requirements for safety, reliability and maintainability that made it as one of the most well-known panels in electrical medium voltage switchboards.
some of the main advantages of MC-MNCO series are:
- Dependent on Iran technical knowledge & united with up – to – date technology.
- Optimum safety for both system & operators.
- Operation reliability.
- Equipped with electrical & mechanical interlocks.
- Low maintenance construction and apparatus.
- Supporting different type of circuit breakers and contactors.
Withdrawable part of this panel is lighter than other similar types and could be installed in any kind of
buildings without any need for flat floor. In addition, this part provides complete safety for maintenance & repair staff. With this withdrawable part, interlocking system can for, there is no need for a flat floor for moving in/out the Withdrawable part. One track is provided for a set of switchgear which is designed based on the requirements of the industry and easy removal. Type MC-MN switchgear provides both external and internal protection.
External protection which is:
Complete enclosure of the panels.
Internal protection which is provided by:
Inserted metal compartmentalization with enforced-operation shutters. (Optional arc-resistant )
Easy maintenance & maximum safety
In this panel, there is no needed to open the door for issuing open/close commands, moving the withdrawable part, opening / closing the earthing switch. Also ensure maximum safety for personnel, panel is preventing against wrong maneuver (according to VDE 0105-part 1 St.)
Interlocking system is designed to provide the following advantages:
- At the time of moving withdrawable part from test condition to operation condition, the door of the panel always can be remained closed.
- At the time of closing earthing switch, circuit breaker shall be opened and withdrawable part shall be in test position.
- During racking-out of withdrawable part, circuit breaker shall be opened.
When earthing switch is closed, withdrawable part cannot be put into service position and closing command to C.B cannot be issued.
Earthing handle that opens & closes the earthing switch can be placed in its proper position only when all interlock conditions are met. A handle which only could be placed in its position if all interlock conditions are satisfied, will do the draw out mechanism part.
