Equipment and systems covered by this certificate are as follows
Junction boxes series S.1-…, S-…, GUA-.., EAH-…The boxes are basically manufactured in aluminium alloy.They can also be manufactured in stainless steel AISI 303-304-316 or in cast iron GJS.

The boxes manufactured in aluminium alloy or in stainless steel can have a ambient temperature range of -40 ÷ +150 °C, while the boxes manufactured in cast iron can have a ambient temperature range of -20 ÷ +150 °C.

The standard O-Ring, placed in between the body and the cover of boxes, in order to obtain an IP hold, is made of Silicon material. The maximum temperature of the gasket shall not exceed 160 °C in service.


See annex for further description.

  • Leads connected to the terminals shall not reduce the clearance and creepage distances of the terminal blocks with type of protection Ex-e and Ex-i. . The use of terminal block’s accessories (e.g. chain bridge) can reduce the maximum rated voltage of the terminal; the instructions of the manufacturer must be followed.
  • The cable entry devices and blanking plugs shall be subject of separate certification for type of protection and operating temperatures indicated on the plate. To guarantee the degree of protection IP 66 or IP 67 the threaded coupling accessory-enclosure shall be suitable sealed.
  • The conditions of the installation and use of the terminal boxes included within the safety instruction, provided by Manufacturer, shall be strictly respected.
