 SA series junction boxes: criteria for choosing the right product

When it comes to deciding on an increased safety enclosure, there is a whole series of essential data to be
taken into account if you are to make the right choice: the mechanical strength of the materials, corrosion
resistance, the IP protection rating and IK impact protection rating in the case of enclosures for watertight/
industrial use.

 Protection ratings

IP PROTECTION RATINGS (IEC 529, EN 60529-4, CEI 70-1 ed. 11/92)

The table gives protection ratings in accordance with standard CEI 70-1 ed. 11/92. Ratings are identified by the
acronym IP followed by 2 digits, to which 2 letters may be added, indicating the degree to which persons are protected
against access or other properties There is some variation in the application of ratings 7 and 8 relating to the ingress of
liquids, with these ratings not always meaning that the item is suitable for lower levels (whereas IP rating x4 also covers
the lower levels).
IMPACT PROTECTION RATINGS
This classification shows the acceptable level of strength, when evaluating a product's safety, and is mainly employed in
relation to testing on electromechanical products.

 SA, SAG... series (Ex e) and (Ex i) aluminium junction boxes

SA...SAG series junction boxes are made from aluminium alloy and given an electrostatically applied polyester coating
containing stainless steel particles that is then baked at 200°C. This treatment ensures good UV as well as thermal
stability, providing mechanical impact resistance and excellent resistance when exposed either to salt mist or to marine
and other damp environments. SA and SAG series junction boxes are usually installed in industrial plants where there is
a risk of explosion and fire, classified as Zone 1, 2, 21, 22; they are mainly used as junction boxes and/or for routing
cables to control rooms for analogue or digital signals and for control, monitoring and signalling associated with
equipment such as motors, pumps...etc., or for giving physical readings such as flow rate, level, temperature, pressure,
etc.... The thickness of its walls (7mm) means the SAG series is suitable for direct connection with pipes and fittings
featuring tapered threads. Cortem's custom solutions offer ATEX- and IECEx-certified components and application
solutions devised for use in explosion hazard areas. The expert Cortem team endeavours to meet all customer requests.

Cortem Group labels its products with a non-removable adhesive label featuring a hologram and
an alphanumerical univocal code, as a safety measure against the illegal sale of fakes so that
all the products are guaranteed as original. Non-compliance with the International standards
entails serious risks for the environment, especially for those working daily on the plants.

TYPE AND APPLICATION

Choosing an appropriate container is a key step in the project development process, making it essential to approach the decision
systematically, evaluating all variables methodically: where our equipment is being installed, the environmental conditions on site,
what degree of protection it must have, what space is available and how it is due to be set up. Once you have processed all this
information, you should be able to determine which product best suits the design requirements in question.
ENVIRONMENTAL CONDITIONS
The first factor to consider is what environmental conditions the equipment is going to be installed in, whether it will be indoors or
outside, and what environments it is required to operate in: pharmaceutical, chemical, petrochemical, food, shipbuilding, agricultural
industries...
DIMENSIONS
The size of the space available for inserting the enclosure and its components must be determined early on in the process.
DESIGN
Taking into account the technical aspect, product design and appearance is also important in ensuring the equipment to be installed
in the enclosure is integrated seamlessly. A Cortem team of experts is on hand every day to address your questions and come up
with the best solutions.
Cortem enclosures have passed:
- IP protection testing;
- IK strength testing;
- salt mist testing for corrosion resistance;
- heat resistance testing;
- low temperature resistance testing.

SA, SAG... series Features of junction boxes with terminals

These enclosures are customized based on size, on the number of terminals or cables they are due to accommodate, or taking into account the number
of cable entries and cabling requirements inside a system. Hence we can produce tailor-made solutions as long as you provide us with the appropriate
parameters required at the quote request stage, such as the number of cable glands, unions or sealing fittings to be installed, so that we can determine the
most suitable size of enclosure. All terminals can be fitted with your requested accessories and mounted on special rails that are fastened to the enclosure's
internal mounting frames. Terminal strips can be arranged in various ways, as specified by the customer and always within the limits allowed by the certificate.
The options are vertical, horizontal, in a number of rows, or on different levels using suitable spacers.

Eg. 2x22= 2 rows of 22 terminals (total 44 terminals). The maximum number of standard terminals refers to the mounting of CABUR and/or
WEIDMULLER terminals.
The data in the table are given as a rough guide only based solely on the size of the enclosures and the space taken up by the terminals.

The permissible maximum power dissipation, in order to retain a T6 temperature class with an ambient temperature up
to 40°C or T5 class with an ambient temperature of 55°C, is not to exceed the values given in the tables below.
For an ambient temperature of +60°C or +65°C, maximum power dissipation must be reduced by 25%, and rated
current reduced by 15%.

The maximum current values for terminal boxes used for low current circuits (signals) with temperature class T6 and
maximum ambient temperature +60°C or T4 and maximum ambient temperature +65°C and +85°C are always as
given below:
+60°C T6 -> max 1A Ex e, max 100mA Ex ia
+85°C T4 -> max 10A Ex e, max 100mA Ex ia
On the following pages, the table values refer to the maximum number of conductors allowed for a conductor with a
given cross-sectional area and subject to a given maximum current. All incoming wires and internal links (made by
wires) count as wires; earth connections do not count.

When mounting rails are installed on the internal mounting plate (and not directly on internal ribs of boxes), the number
of terminals may be slightly less than the number indicated in the tables.
Other types of terminals can be used up to the space limit of the box. Whatever the case, the terminals used shall be
ATEX and/or IECEx certified. Size 35mm2 terminals can be used for conductors with a cross-sectional area of 25mm2.

The maximum number of terminals and the maximum number of rows shown in the tables is an indicative value; pay
attention to the cable entries installed on the sides of boxes. The internal overall dimensions of cable glands and the
overall dimensions of conductors must be taken into consideration to allow for wiring.
In some cases, it may be necessary to reduce the number of terminals or the number of rows.

Example for the calculation of the maximum number of conductors.

Refer to table for SA141410: 6 conductors with 6mm2 cross-section with 26A continuous current is the limit of this box.
Consequently, SA141410 is suitable for containing 3 x 6mm2 terminals (2 conductors for each terminal) with a max.
current of 26A. There is space for 11 x 6mm2 terminals in the box. The remaining 8 terminals (11-3) can be added and
used for low current circuits indicated in area “yellow” of the table (in this case max. 8-10A).

Combined mounting for electrical circuits with different sized cables is possible provided the values given are used
proportionally.
For example:

Nominal X-sect. area (mm2) Current (A) Quantity Capacity

2,5 8 16 (di 46) 34,8%

4 11 12 (di 36) 33,3%

10 26 4 (di 13) 30,8%

Total 98,9% <100%

Instructions for determining which enclosure is best suited based on the planned number of conductors and terminals.

: In this unfilled area, provided the relevant instructions are followed and the permitted measurements given for
devices housed inside the enclosure are complied with, any number of terminals can be added up to the space limit of
the box.
: Fitting in this unfilled area is not covered by this certification.
“C. No.” row: values shown in the cells define the maximum number of CABUR terminals physically allowed inside the
relevant enclosure. These values are expressed as a product of the rows multiplied by the number of terminals on each
row.
“W. No.” row: the same as above, but referred to the Weidmuller terminals.
The terminal brands are mentioned just to give an idea of the number of terminals that can be installed inside the
enclosures.
The other values shown in the cells along the table’s diagonal define the maximum number of conductors allowed,
depending on their cross-sectional area and the maximum current that flows through them.

 Features of junction boxes for control, monitoring and signalling units

Control, monitoring and signalling units are used to produce control boards that, when positioned near the electrical equipment being controlled, enable the
electrical system to operate correctly and guarantee the safety of personnel when maintenance is being performed on the system. Because they are fitted with
a Manual/Automatic selector, they allow operators to select the appropriate conditions to enable work to be performed entirely safely. They offer protection
and control for electrical equipment and control circuits located in explosion hazard areas and in particularly aggressive environments. They are used to hold
electrical equipment, such as switches, indicators, contactors, transformers, analogue and digital components, etc.... with the option of external control by
using lid-mounted Cortem control and signalling devices, such as control levers, pushbuttons, indicator lights, etc.... Cortem designs, develops and supplies
full cabling for one or more enclosures tailored to your specific requirements, producing panel boards - including even extremely complex solutions - and
providing a full inspection and testing service on request.
