Frequently Asked Questions

What are the main applications of the MNS low-voltage switchgear?

The MNS low-voltage withdrawable switchgear is widely used for power distribution centers (PC) and motor control centers (MCC), as well as power factor compensation systems in power plants, industrial facilities, and large commercial infrastructures.

What is the maximum rated operational current supported by this system?

The switchgear main busbar can support a maximum operational current of up to 5000A, while the vertical distribution busbar accommodates up to 1000A.

What protection degrees (IP ratings) are available?

Standard protection ratings comply with IEC529 and DIN 40050 standards, including IP30 (solids > 2.5mm) and IP40 (solids > 1.0mm). A higher protection rating of IP54 for dust and splash water protection can be customized upon request.

Which circuit breakers are compatible with the PC cabinets?

The power distribution center (PC) cabinets can integrate various renowned circuit breaker models, including Emax, MT, 3WN, AH, and ME series.

What precautions should be taken during equipment hoisting and moving?

When lifting, transport angle plates should be used ensuring the wire rope angle does not exceed 120°. Prying or applying force directly against the equipment enclosure is strictly prohibited, and minor adjustments must only be pried at designated test frame corners.
