 I. Overview    

MNS low voltage switchgear is suitable for system with AC 50(60)Hz and rated working voltage up to 660V, and applicable for power generation, transmission, distribution, change-over and consumption equipment control. It conforms to relevant standards such as IEC60439-1, GB7251.1 and JB/T9661.

 II. Structural characteristics   

1. The frame is of combined structure with basic framework made up of assembled C-profiled bars;

2. Each cubicle is partitioned into horizontal busbar compartment, drawer compartment and cable compartment. Steel plates or flame-retardant plastic function boards of high strength are added as partition between each compartment and metal plates with ventilation holes are added as partition between drawers as to prevent  switching element from accidents caused by flashover due to fault or short-circuit of busbar with other circuits;

3. Compact design enables to accommodate more function units within limited space;

4. Structure members have great versatility and flexible assembly. Taking E=25mm as module, the structure and withdrawable unit can have random combination as to satisfy the demand of system design;

5. The busbar is protected by plastic function boards of high-strength flame-retardant and high insulation strength, which has performance against fault arc as to ensure safe and reliable running and maintenance;

6. Mechanical interlock gear of drawers in different sizes conforms to stipulations laid by standards and has three obvious positions as making, testing and breaking, with safety and dependability;

7. It is adopted with high-strength flame-retardant engineering plastics, which effectively enhances protection performance;

8. High degree of versatility and standardization, convenient assembly, reliable quality assurance;

9. Corresponding degree of protection may be chosen subject to different working environments.
