1. MNS Type 0.4KV 6.6kv 630A 1000A 1250A Low Voltage Drawer Switchgear
MNS low voltage switchgear is a metal enclosed low voltage power circuit breaker switchgear offers excellent flexibility due to the modularity of both the electrical and mechanical design. The modularity enable customization of the structural design, interior arrangement and degree of protection. It's modular design is widely used for power distribution and motor control.

3. Mechanical design:
1. Frame construction: The basic elements of the MNS frame construction are "C" shaped steel profiles with a 25mm hole pitch. This 25mm equals the dimension of 1E used in MNS to define the area usage within the switchgear. Each cubicle is precision constructed by bolting horizontal and vertical profiles together, to form a rigid modular structure. The profiles are galvanic protected against corrosion.
2. Enclosure: MNS switchgear enclosure is made of sheet steel protected by galvanic coating and powder coating for maximum durability. The fixing of the enclosure with respect to doors, roof plates, rear and side walls is achieved with thread forming screws. Final construction varies depending upon the required degree of protection. In accordance with the general safety philosophy followed with MNS, each compartment and sub-compartment which requires access for commissioning, operation or maintenance, has its own door.
