It complies with GB3906 "3.6~40.5 AC metal-enclosed switchgear and control equipment" and meets the requirements of standard IEC298 "AC metal-enclosed switchgear and control equipment". And has the "five prevention" interlocking function.

 

Model and meaning

 

Conditions of use

  ★Ambient temperature +40℃, lower limit -25℃;

The altitude does not exceed 1000m;

The relative temperature is less than 95% on average, and less than 90% on average;

       ★There is no place with fire, explosion hazard and severe vibration;

Severely polluted by surrounding air, non-corrosive or combustible gas, steam and conductive dust;

 

Structure characteristics

    ★Using integral assembly structure, light and beautiful, can be combined in any combination for easy installation and expansion.

     ★It can be equipped with FN12-12 type pneumatic load switch and combined electric appliance, and it can also be equipped with FZN25-12 type vacuum load switch and combined electric appliance. Small size, maintenance-free, three-phase linkage structure

The fracture was clearly separated.

     ★Load switch, electrical combination, flexible installation, can be installed, left and right sides up and flip chip (FZN25 does not reverse).

     ★It can be operated manually and electrically, with remote control function.

     ★ Equipped with mechanical interlocking linkage device, perfect and reliable, to meet the "five-way" function.

A. The load switch is closed, the grounding switch cannot be closed, and the front door cannot be opened;

B. Load switch switch, the grounding switch can be closed, when the grounding switch is closed, the door can be opened;

C. The grounding switch is closed, the load switch cannot be closed, and the front door panel can be opened;

Gate D. Grounding switch, load switch, separable switch, unable to open the front door;

E. The cable enters the line, the line electrical, no matter the load switch is in the closed position or the closed position, the electromagnetic lock is controlled by the front door panel and cannot be opened. (In addition to using special keys to unlock emergency

outer).

     ★The load switch is equipped with a linked insulation protection valve or a transparent insulation cover to shield the electrical contacts to ensure personal safety.

It is reliable for installation, operation and maintenance on the front wall.

     ★The working status of the cabinet components can be clearly observed through the front door with observation window.
