Enclosures made from stainless steel and sheet steel Reliable protection An integrated duct for dust and moisture keeps contaminants or moisture from penetrating inside when the enclosure is opened. The outer earthing bolt comes with an IP67-certified seal mechanism and is protected against accidental rotation. Versatile assembly options Mounting bolts are attached inside the enclosures so that DIN rails and mounting plates can be installed within.
Aluminium enclosures Aluminium enclosures The Klippon® K Series enclosures can be used in a variety of applications for protecting terminals, switches, power supplies, control/display elements or electronic components.
Aluminium enclosures High IP protection The seals are fully closed without adhesive points so that the entire enclosure has a better seal. This seal ensures an IP protection level from IP66 to IP68 (subject to use). Mounting options Suitable mounting plates for attaching DIN rails or block terminals are available as options. Standardised distributor enclosure The Klippon® K enclosures are already fitted with threaded holes.
Plastic enclosures (Polyester / polycarbonate) Plastic enclosures The polyester enclosures (the Klippon® POK and TBF ranges) and the polycarbonate enclosures (MPC and FPC ranges) are ideal high-quality solutions for electrical connectivity applications. These enclosures are suitable wherever corrosion resistance, shock resistance and a high class of protection are required.
Plastic enclosures (Polyester / polycarbonate) Easy to install The enclosures feature holes for attaching DIN rails and mounting plates using self-tapping screws. The FPC and MPC enclosures are also equipped with support slots for circuit boards. Sturdy and impact resistant Because of their high fibreglass content, the enclosures are extremely rugged, weather resistant and can resist impacts up to 7 joules.

A closer look at Weidmüller’s production of stainless steel enclosures A closer look at Weidmüller’s production of stainless steel enclosures – manufacturing expertise at the highest level Weidmüller provides the global market with high-quality Klippon® Protect enclosures manufactured at our main enclosure production site. These enclosures are built to satisfy the toughest industrial demands. During production only the highest quality materials are used along with state- 1.
A closer look at Weidmüller’s production of stainless steel enclosures 3. Process-compatible welding method 4. Attaching the inner-thread sockets The moveable corners and edges of the sheet are welded into a single unit in a fully automated process. They are fixed in place with a standardised clamping mechanism. An inert gas is used on both sides during the welding process to protect against corrosion.
A closer look at Weidmüller’s production of stainless steel enclosures 5. Electro-polishing The Klippon® TB enclosure range is supplied as standard with an electro-polished finish which increases corrosion resistance and reduces surface deposits and germs. We have installed one of the most modern computer-controlled electro-polishing facilities in the world at our production site. This facility was designed and optimised especially for electro-polishing our stainless steel enclosures.
A closer look at Weidmüller’s production of stainless steel enclosures 6. Seals 7. Mounting The seals for the lid and gland plate are cut to shape in a flexible and precise process that uses a blade with a cutting speed of up to 1000 mm/s. INFO: A reliable seal ensures protection against external influences ven at extreme temperatures. Thus the seal is one of the most important components of an enclosure. The seal must exhibit a high degree of resilience so that it can remain functional.

Customised production Integrating, augmenting and customising: perfectly complimenting your application needs A variety of customised configurations can be constructed at our enclosure manufacturing facility. Weidmüller not only produces enclosures; we can also customise them according to specific customer requirements. A wide range of customised options are available, including customisation with holes and cut-outs.
Customised production The new Klippon® TB enclosure range consists of 12 sizes and 3 standard depths. A variety of enclosure variants can then be configured based on these. The enclosures can be fitted with two different locking systems on request. They can also be ordered with various materials, surface and sizes. The structured system of accessories for the new Klippon® TB enclosure range means that you can easily adapt the enclosure to the specific requirements of each application.
Expertise / Approvals International approvals \ Weidmüller’s products and services meet our own strict standards as well as international quality and safety standards. All Weidmüller enclosures are specially tailored to the harsh, fluctuating conditions found in demanding industries. They are certified for compliance with international standards and comply with the latest ATEX and IECEx directives concerning areas requiring explosion protection.
Tested down to the details Quality you can depend on ... Weidmüller enclosures are often exposed to harsh conditions during use. Because of their excellent quality, they provide years of reliable protection against water, dust, strong impacts, vibration, corrosion and extreme temperature fluctuations. The Klippon® TB enclosures have been certified and approved according to the new IEC/EN 60079 set of standards.
Tested down to the details Empty enclosure standard according to DIN EN 62208 Static load The load capacity of an enclosure is tested using a static load test. The enclosure is subjected to a certain load (a weight specified by the manufacturer) for one hour. No damage should be incurred by the enclosure during this time. Depending on their sizes, the Klippon® TB enclosures can withstand loads ranging from 15 to 300 kg.

Tested down to the details EX tests according to IEC 60079-0 Long-term thermal test During use, the enclosures may be exposed to extremely high and low temperatures, and to extreme temperature fluctuations. The heat/cold resistance test determines the temperature range in which the enclosures maintain their full functionality. Thermal stability According to the IEC directive 60079-0 edition 2011 section 26.8, the enclosures must be subjected to hot storage in two steps: 1.
Tested down to the details Additional testing Torque test Computed tomography (CT) During this test, the lid, gland plate screws and earthing screws are all tightened and loosened from the enclosure using the torque recommended by the manufacturer. This is repeated five times. If the torque value required to destroy a rivet or shear off a bolt is greater than the specified torque, then the test is considered passed.
Tested down to the details Flammability test Surface analysis The flammability characteristics of plastic are tested here and categorised in the following classes according to UL 94 : Scanning electron microscopy provides a high-resolution view of the surface that also has a high depth of field. When used together with electron probe microanalysis (or EDX: energy dispersive x-ray analysis), a qualitative and quantitative analysis of the chemical composition of the surface is possible.
The basics of explosion protection The basics of explosion protection PP )OD HQ \J 2[ An explosive atmosphere is created by an air mixture of flammable gases, vapours, mist or dust. When an ignition occurs in an explosive atmosphere, the reaction continues independently in these atmospheric conditions. Such atmospheric conditions are in the range from 0.8 to 1.1 bar absolute pressure and –20 °C to +60 °C mixture temperature.
The basics of explosion protection Equipment protection level (Equipment Protection Levels - EPL) Mining operations at risk of firedamp (Group I) EPL Ma Devices to be installed in a mine that have a „very high“ level of protection; where there is sufficient certainty that no ignition source exists, even when gases escape during operations.
The basics of explosion protection Equipment group II applies to equipment and devices intended for use in other places liable to be endangered by explosive atmospheres. Increased safety Ex e – no sparks and surface temperature limited to a safe level Equipment group II is subdivided into three categories: This increased safety level is intended for products that encounter no sparks during normal operations or during faults.
Grundlagen zum Explosionsschutz The enclosures must be stable enough that they are not deformed or destroyed by the pressure created. All of the enclosure’s couplings and connections are designed so that they will not transmit an internal explosion to the surrounding outer atmosphere. These couplings are referred to as ignition gaps. The explosion group (IIA, IIB, IIC) is relevant for this ignition protection type. Devices using this protective strategy may not be used in Zone 0.
