FIX TYPE M.V. CUBICLES
   
 

Fix Type M.V. cubicles produced at ISC according to IEC 298, are used in M.V. distribution system.

ADVANTAGES:
1- Ease of manufacturing, installation and assembling due to screw and -nut- type structure.
2- Possibility of assembling at the site.
3- Including protection for system and operator.
4- Possibility of IP44 (as request)

STRUCTURE:
The structure is manufactured from steel sheet ST 1303 occording to DIN 1623, main profiles of structure is "C" type, this is why it is possible assembling parts to each other easily. After cutting, punching, bending and painting, the parts are assembled. Therefore changing, repairing or disassembly of parts is very easily accormplished.

INTERLOCKS AND SAFETY FEATURES
1- Special suitable vent is furnished at the top of cubicle for exit of gases due to short circuit.2- On-off switches are possible from front easily when the door is closed.

3- Between circuit breaker and isolator, between load break switch and earth switch there is special interlock so that it is impossible to operate them at the same time as safety features.
