Premset main circuit is totally protected against harsh environment influence, thanks to 2SIS technology..but, what about the rest : mechanism, auxiliaries,control ?
Specific care has been taken to reinforce the harsh environment withstanding on mechanism and auxiliaries as well :
- mechanism is more robust, because designed on common platforming from the simplest - for switch - up to the heavy duty CB fitted with stored energy mechanism.
- specific care has been taken to select the mechanism parts plating, and tested accordingly in harsh environment
- tripping and operating coils are encased in a sealed core, so protected against condensation and dropping water.
- motor is encased in a protection aluminium cover
- auxiliary switches are sealed-type, waterproof.
