Cortem SA-SAG Aluminium Ex eb Junction Boxes, 18 Sizes
Description
Aluminium Ex eb junction boxes in 18 sizes for Zones 1, 2, 21 and 22
The Cortem SA and SAG series are increased-safety (Ex eb) junction and terminal boxes made from low-copper aluminium alloy with an electrostatically applied, stainless-particle polyester coating baked at 200 °C for UV, thermal and salt-mist resistance. They are used as junction boxes and to route analogue, digital, control and signalling cables to control rooms from motors, pumps and field instruments such as flow, level, temperature and pressure transmitters.
Two wall thicknesses are offered. SA models are the lightweight series with thinner walls and plain through holes only; SAG models are the heavy-duty series with extra-thick walls (7 mm), so the body can take threaded entries and connect directly to pipes and fittings with tapered threads. The same boxes can be supplied with Ex i terminals, with equipment such as fieldbus modules, proximitors or heaters, or as control and signalling enclosures.

Terminal capacity, options and what to confirm
The datasheet gives the maximum number of terminals by cross-section, for example 11 terminals of 1.5 mm2 in the SA090907 and two rows of 70 in the SA302310, based on Cabur or Weidmuller terminals as a rough guide. Only ATEX-certified terminals from approved makers (Cabur, Phoenix, ABB Entrelec, Wago, Weidmuller) may be used, Ex i terminals are blue and must be separated from Ex e terminals, and permitted dissipation falls by 25 percent and rated current by 15 percent for +60 or +65 °C ambient.
Options include anti-condensation interior coating RAL 2004, external colours, breather and drain valves, a stainless steel mounting plate, terminal rails and a single centre hole in the bottom (1 inch NPT or M32x1.5). Holes are drilled by Cortem or an ATEX-notified partner. Confirm the size and terminal count, the required temperature class, whether Ex i circuits are present and the cable gland sizes.
