Approvals that we obtain show proof of the quality of our products. These are granted by independent organisations after functional or suitability tests. They are the condition for use in certain markets or application fields. The competence of the accredited testing laboratory is confirmed. The correctness of technical data is top priority for users.
In order to ensure that our products remain at the cutting edge of technology, we have worked closely and successfully with experts at DEKRA Certification B.V. inspection agency. This excellent cooperation helps us to be completely sure of the electrical safety of our products. Experts at an impartial inspection agency help us to satisfy all of the latest regulations and to meet our customers' current challenges.
Our innovative terminal blocks, for example, have been examined and certified to the highest possible extent by the DEKRA Certification B.V. testing authority for their conformity to international (IEC) and European norms (EN). These tests are documented in the existing inspection reports.

UL (Underwriters Laboratories Inc.®) is one of the world's leading organizations for the testing and certification in the field of product safety. UL approval is often required, especially for the international market. For this reason, many CONTA-CLIP products have UL approval. The UL listing contains important information about the product and its use, such as:

As of 1st July 2003 products placed onto the market or taken into service for the first time must comply with the provisions of the Directive 2014/34/Eu covering explosion protection. This Directive supersedes previous Directives and national regulations relating to hazardous area applications. Please observe that the new Directive is also to be applied to such products that were introduced onto the market in accordance with previous directives. In addition, it also applies to products that are intended for use in dust-laden environments. Traceability is required for all Ex products. Each user and re-seller must guarantee the traceability of the products.

The insulation housings of CONTA-CONNECT products are made from high quality PA 6.6 polyamides. Such materials have a flammability classification of UL 94-V2 or UL 94-V0. This modern insulation predominates in terminal products and has been approved by all of the relevant regulatory bodies, including CSA, UL, PTB, SEV, VDE, DEMKO and NEMKO. It has a creepage current resistance level of CTI 600, in accordance with IEC 112/DIN 0303/part 1.
It also has excellent resistance to micro-organisms, bacteria and termites. Polyamide is also resistant to ultra-violet light and ageing. Polyamide 6.6 absorbs moisture from its surroundings (about 2.8% on average). This helps the plastic to stay elastic and non-brittle, even at temperatures down to -40°C. It has a semi-crystalline molecular structure and is stabilized by thermal ageing. This ensures that it maintains its excellent electrical, mechanical and chemical specifications even at temperatures up to 120°C. The peak temperature allowed for shortterm use is about 180°C. The melting point of the material is at 250°C. Polyamide 6.6 is flame resistant and self-extinguishing in compliance with VDE and ASTM.
None of the insulating materials and colouring pigments used by CONTA-CLIP contain asbestos, phosphor, cadmium or halogens.
All metal parts used in CONTA-CLIP products are selected using state-of-the-art technology. During the production process, they are closely monitored by the CONTA-CLIP quality management system.
The metal parts in CONTA-CLIP products are galvanized using the most modern techniques available. They feature state-of-the-art surface protection. The steel parts are galvanized as standard practice. An additional passivation with a blue chromate layer is then applied to the zinc coating. Copper and brass parts are normally coated with a tin layer. This tin coating provides consistent, good electrical characteristics and also an excellent protection against corrosion. Solder lugs and solder pins are also coated with a tin layer. An additional layer of nickel is present under the tin layer in order to ensure that the soldering characteristics do not deteriorate over longer periods. The springs in the tension-spring and pressure-spring mechanisms are made from high-quality, rust-proof, acid-resistant steel. This provides them with excellent resistance to their environmental surroundings.
