Enclosures ESA – ESX with Korean Certificate (KC)

Nuova ASP has recently achieved the Korean Certification for its ESA – ESX enclosures which can be used in places where an explosive atmosphere is likely to occur due to the presence of inflammable substances such as gas, vapours, fogs (group IIB or IIC) and/or combustible dusts (group IIIC).
ESA series indicates aluminium enclosures without operator devices while ESACS indicates enclosures with operator devices.
ESX series indicates stainless steel enclosures without operator devices while ESXCS indicates enclosures with operator devices.
ESA – ESX and ESACS-ESXCS enclosures have been designed to ensure the required protection level (IP66) even in case of equipment faults which have been taken into consideration during the relative risk analysis.
The enclosures can be equipped with threaded holes on the walls, cover, and in some cases on the bottom, to allow the installation of control and warning accessories or the passage of cables.

Type of protection Ex d, e, ia/ib, ia, ib, mb, IIC T6, T5, T4
Ex tb IIIC T85°C or T100°C IP66
Degree of protection IP66
