MNS Low Voltage Withdrawable Switch Cabinet
MNS type low-voltage withdrawable full set of switchgear is an innovative low-voltage switchgear designed by our firm to fulfill the industrial development demands of our clients. It relates to and enhances the design of local and international low-voltage switchgear.
The MNS-type low-voltage withdrawable full switchgear is appropriate for a variety of power supply and distribution equipment. It may be widely employed to satisfy energy demands in a variety of low-voltage distribution systems, including power plants, substations, industrial and mining businesses, buildings and hotels, and municipal projects.
MNS-type low voltage withdrawable switchgear is the modular drawer family descended from the ABB MNS system — cabinets, compartments, and drawer positions laid out on a 25 mm module grid so a line-up can be rearranged as load schedules evolve. For plants that expect expansion, re-balancing, or frequent process changes, that modularity weighs as heavily as the initial feeder list itself.
We assemble MNS-type boards around your present load schedule plus the growth you expect — spare compartments, relocatable drawers, and standardized internals that simplify later changes. Production draws on fifteen years and 4,000+ projects of fabrication practice, with CNC punching and bending holding the module grid true across every cabinet in the row.
Feature of Low Voltage Withdrawable Switch Cabinet
Compact design: Contain more function units with less space.
Strong versatility for structure, flexible assembly. C type bar section of 25mm modulus can meet the demands of various structures and types, protection grades and operating environments.
Adopt standard module design, can be combined into protection, operation, transfer, control, regulation, measurement, indication, etc such standard units. Users can choose assembly according to requirements at will. A cabinet structure and drawer unit can be formed with more than 200 components.
Fine security: Adopt high-strength antifoaming type engineering plastic pack in large quantities to effectively enhance the protective safety performance.
High technical performance: Main parameters reach the advanced level at home.

Frequently Asked Questions
What sets MNS apart from GCK and GCS?
Its 25 mm module grid, inherited from the ABB MNS system: compartments, drawers, and internal hardware all follow one dimensional rhythm, so space can be re-planned and drawers re-housed as the load schedule changes. GCK and GCS are equally capable withdrawable families with their own formats — the right pick usually follows your existing fleet and spares.
Why does modularity matter for future expansion?
Because the expensive part of a retrofit is re-fabrication. On a module grid, adding a feeder or upsizing a drawer is a re-arrangement exercise within existing cabinets rather than new steel — downtime and cost drop when the second phase arrives, which is why growing plants standardize on modular systems.
Can MNS line-ups mix drawers and fixed compartments?
Yes — withdrawable drawers for motor and frequently serviced feeders, fixed compartments for incoming frames and stable loads, all inside one row with a common busbar system. The mix is set by your maintenance strategy and budget.
Which standards govern MNS-type boards?
The GB 7251 series corresponding to IEC 61439 — the same design-verification regime as other national-standard LV assemblies. We reference the standards in design and supply the documentation with the delivered board.
