ENCLOSURES & PANEL BUILDING SOLUTIONS SUPPLEMENT
MEETING THE STANDARD In the crucial area of corrosion protection, a requirement for electrical switchgear enclosures under IEC 62208 and IEC 61439 is vital for ensuring that the enclosures offer consistently high levels of protection, even after many years of operation. To meet the required standards, Rittal’s enclosures are protected by a process that has several stages, from cleaning and progressing, to powder-coating the primed enclosure. When it comes to testing enclosures (in
accordance with IEC 60068-2), a distinction is made between indoor and outdoor installations. The corrosion process itself would normally take place over several years, but this can be accurately simulated in just a few days using what is known as a salt spray test.
SAFETY IS KEY One of the key objectives that IEC 61439 strives to promote is the safety of p eople who operate electrical switchgear systems, or work in close proximity to them. The standard, therefore, also includes several specifications for the mechanical properties of enclosures. For example, enclosure doors must not open during short circuit shutdown. If one is blown from its fixings, following an electrical fault, people in the vicinity could easily be injured. This is another reason why it is important for an enclosure to maintain its original mechanical strength, even after several years, and not weaken due to rust or any other factors.

LED LIGHT SERIES NOW COMPLETE
Rittal is to launch two new versions of its LED system lights, thus completing the range. Its series of specially designed lights will include 600 and 400 lumens of light output (luminous flux), to add to the current 1,200 and 900-lumen versions. This means that Rittal can now offer lighting solutions to suit all sizes of enclosure, from small housings right up to large systems. The new lights are designed to enable control and switchgear manufacturers to provide lower light output for smaller enclosures. The 600-lumen version meets the standard requirement for the large TS 8 enclosure, while the 400-lumen lights are suited to wall-mounted enclosures, such as the Rittal AE compact series. An optical cover made of transparent plastic, in which a Fresnel structure is integrated,
provides optimal illumination. It focuses the light so that the inside of the entire enclosure, even the bottom, can be illuminated so that the light reaches all the places it is needed. All the lights have been designed for a wide-range of voltage inputs (100-240V AC) and can therefore be used in every market all over the world. This cuts storage costs and simplifies selecting products. The lights can be adapted to any type of installation, and fitted either vertically or horizontally
in the enclosure section. They can be mounted quickly and easily just by clipping them into the TS 8 enclosure, and can be screwed into the section if required.
