Technical characteristics


CHARACTERISTIC: Series 3000 EExe boxes are suitable for containing terminals for junction systems. They must be installed according to the instructions of standards EN 60079-14 and EN 50281-1-2.

MATERIAL: Box and cover manufactured in aluminium alloy.

SURFACE FINISH: Coated with grey epoxi polyester powder (similar to 7042 RAL) with coarse texture. This treatment provides colour with an excellent resistance against UV light and temperature changes, as well as a high protection against chemical agents, saline mist and wet environments.

CLOSURE:  By means of captive flush screws. They may be supplied either in stainless steel or in a steel with anti-corrosion treatment.

WATERTIGHTNESS: A neoprene bedjoint embedded in the cover provides the box with a degree of protection of IP-65, according to UNE 20324, CEI 529 and EN 60529.

FIXING: Wall mounting by means of adjustable lugs in order to place the box in any position.

MOUNTING PLATE AND TERMINALS:The box has inside and at the bottom thickness parts to fix the mounting plate on with screws without external drilling. Active or earth terminals will go mounted onto the mounting plate, always by APLEI, S.A.. These terminals have certificate of component according to Directive 94/9/EC. The correspondent charts of each box type indicate the maximum number of terminals by section.

GROUND CONNECTION: The enclosures have an external connection and an internal connection consisting of one screw with nut each, both in stainless steel. It allows the joining of a mass equipotential conductor of 35 mm2. The anti-loosening is ensured by a stainless steel split washer

ENTRIES: The boxes are supplied with entries for the assembling of cable glands and fittings. These entries shall have been made by APLEI, S.A., and they will have always been carried out in the boxes sides (never either in the bottom or in the cover). The maximum allowed number of entries in each side depends on the entry type according to the test executed to certify the enclosure. The correspondent enclosed chart of each box may be taken into consideration as a reference. The entries may be carried out following several standards, being the most usual the standards ISO 261 for metric thread.

TEMPERATURE CLASS: T6. Using standardised terminals and under normal operating conditions the temperature reached in the external surface of the enclosure is always under 85ºC.


IP-67 protection grade can be supplied on request.
