Schneider Electric 13982 Kaedra 18-module IP65 enclosure

13982: Kaedra 1 x 18 module weatherproof enclosure

The 13982 is a surface-mounted weatherproof enclosure from the Schneider Electric Kaedra family, listed in the datasheet under the Mureva Enclosure range as an enclosure for modular devices. It has single row of 18 modules each, which gives 18 modules of 18 mm, and a transparent reversible cover. It is supplied with a distribution terminal block and the fittings listed below. Seven Star LLC supplies the 13982 in Oman and the GCC as an independent supplier based in Muscat.

The title of 13982 reads as follows: Kaedra is the family name, “for modular device” means the interior carries standard DIN-rail devices, “1 x 18 modules” gives the rows and the capacity per row, and “1 earth (screw connection) with 22 outgoers” describes the terminal block content. The result is a compact outdoor or semi-outdoor board for a handful of circuits, such as a pump, a gate, lighting or a small service point.

Weatherproofing: IP65, IK09 and UV on the 13982

IP65 as defined in IEC 60529 is dust-tight and protected against water jets, and IK09 under EN 50102 is an impact class that suits exposed locations. The datasheet also gives UV resistance class 3 under ISO 4582 and a fire resistance of 650 °C by IEC 60695-2-1. Together they describe a polymer box intended for sites where sunlight, rain and knocks are expected.

These ratings hold only if the box is closed, the cover seal is seated and the cables enter through suitable glands in the pre-cut positions. The datasheet gives 17 PG ISO pre-cutouts, and any unused opening must be sealed. Environmental ratings of a finished installation depend on the glands as much as on the enclosure.

Capacity and thermal limit of 13982

The datasheet lists 18 modules of 18 mm for 13982, equal to 36 pitches of 9 mm. The rated current is 90 A, and the power dissipation figure is 34 W, which is the value to keep in mind when you fill the enclosure. A sealed polymer box releases heat slowly, so crowding it with modules that each lose a few watts can push the internal temperature near the limit, especially in direct sun.

Add up the dissipation of the devices you plan to install, compare it with the stated value and leave space around hot components. For this unit the enclosure can be worked out against the 90 A rating and the 34 W dissipation together, not against the module count alone.

Typical use of 13982 in Oman and the GCC

Outdoor distribution in Oman and the GCC has to cope with strong sun, heat, dust and sometimes salt-laden air near the coast. The this unit is a polymer box with listed IP65, IK09 and UV resistance, so it is considered for pump stations, street and car-park lighting feeders, irrigation controls, small utility cabinets and temporary site supplies. For harsher chemical areas or corrosive plant zones the owner should check the material suitability separately, since the datasheet speaks only of the properties listed above.

Kaedra family overview and where 13982 sits

The table lists the three references handled in this group. The this unit is the 1-row member, and it is the right one when a compact outdoor or semi-outdoor board for a handful of circuits matches the job. Moving to a larger reference gives more modules and a higher rated current, at the cost of higher dissipation and a larger footprint on the wall.

Installation and maintenance of 13982

Fix the enclosure to a flat, rigid surface with fasteners suited to the wall material, keep the cover seal clean and check it for damage whenever the door is opened. The cover is reversible, so decide the opening side before mounting. Weight of the empty unit is 2.681 kg as packed, so one person can usually lift it, but a larger board with devices installed should be handled with care.

Inspect the box periodically for UV discolouration, cracked glands and moisture, and retorque the terminal block screws during scheduled maintenance. A fuller inspection after sandstorms is a sensible habit in desert sites.

Selection checklist for 13982

• Count the modules needed, including spares, and compare with 18.
• Check the total device dissipation against 34 W.
• Confirm the incoming current is within 90 A.
• Plan cable entries against the 17 pre-cut positions and choose glands that keep IP65.
• Check wall space for 448 x 280 mm and a depth of 160 mm.
• Decide if the optional keylock is wanted.
• Check the site temperature against -25 to 60 °C.

Terminal block and wiring on 13982

The this unit carries 1 earth (screw connection) with 22 outgoers, with 11 x 16 mm² + 11 x 10 mm² on the distribution side. The provided equipment is 1 marking kit, 1 wiring strap, 1 terminal block 22 holes, 1 terminal block support. An earth block with screw connections lets the protective conductors be gathered in one place, and the wiring strap and marking kit help keep the layout tidy and the circuits identified.

The enclosure is Class II, with double insulation. That does not remove the need for correct earthing of the devices inside; follow the wiring rules for the installation and label every outgoer. A single rail row keeps the wiring path short, which makes later changes easy.
