R. STAHL's local control stations are custom-made for their intended purpose. The choice is yours – from the material and dimensions to the features and accessories the control equipment should consist of. The 8150 series sits perfectly alongside R. STAHL's portfolio of other explosion proof and hazardous areas equipment, including junction boxes, controllers, control boxes and distribution boxes. No matter your requirements,
R. STAHL is your perfect partner to achieve explosion protection and certification all under one roof.
The adaptability for your needs and ATEX certification are not the only features of the 8150 series explosion-proof control stations. Up to four contact elements can be installed under just one actuator. Colors of indicator lamps can be changed via the calotte accessible on the cover. Contained electrical ammeters and voltmeters can be used at ambient temperatures from -40 ºC to +70 ºC. And of course explosion protection comes as standard. Simplify your electrical equipment and people protection.
The components can be configured across different levels in the interior. All contact elements, individual lamps and control elements can be installed directly inside the enclosure cover, making mounting simple. This allows for unprecedented space inside the explosion proof enclosures.
Enclosures are available in different sizes and materials, such as stainless steel and glass-fiber-reinforced polyester resin. The 8150 can also be furnished with an electro polished surface finish – making them advantageous for applications in the chemical, petrochemical and pharmaceutical industries.
The robust ATEX explosion proof enclosures and equipment is suitable for use in all climatic conditions and at extreme temperature ranges. The built-in components and the international certification standards they comply with, vouch for their worldwide usability. The R. STAHL 8150 series has these internationally recognized certificates: ATEX, IECEx, CQST, TR CU, ULB, PESO, GL/DNV, NEPSI, ITRI, and KGS.
What is Explosion Proof?
Engineers are constantly working to improve existing standards to make machines not only more efficient, but also safer to operate, both in regular and emergency situations.Get more news about Box Panel Explosion Proof,you can vist our website!
To help engineers and technicians around the world achieve this goal, The National Fire Protection Association (NFPA) started publishing the National Electric Code (NEC) in 1897.
The code, also known as NFPA 70 and ANSI/NFPA 70, defines various standards related to protection techniques that must be used when designing products intended for use in hazardous locations.
In order to be deployed in such environments, products typically need to also satisfy safety protocols established by the ATEX Directive and IECEx, an international system for certification of equipment for use in explosive atmospheres created by the International Electrotechnical Commission (IEC).
Components designed following these rules must be dust ignition proof, dust-tight, purged and pressurized, intrinsically safe, hermetically sealed and explosion-proof.
Explosion-Proof Standards
To satisfy the explosion-proof standards set out by the NEC and IEC, an enclosure must be able to contain possible explosions originating within its housing, as well as preventing sparks from the inside to ignite vapors, gases, dust, or fibers in the air surrounding it.
Explosion-proof then refers not to the ability of the enclosure to withstand an external explosion, but to contain an internal one, thus preventing internal damages to affect surrounding machinery and people.
The NEC also states that explosion-proof equipment must meet the temperature requirements of the specific application in which it is to be installed.
In other words, the operating temperature of a given device must not be greater than the lowest ignition temperature of the dust or gases in the atmosphere where the component is to be installed.
Products listed as explosion-proof according to NEC are divided into use for use in Class I, Division 1 or 2 locations. Generally speaking, the equipment listed for a higher classification surpasses the requirements for lower classifications.
According to the NEC, products identified for a Division 1 location are permitted in a Division 2 location belonging to the same class, group, and temperature class.
Explosion-proof junction box is a kind of connection device with explosion-proof and strong sealing in the circuit laying. From the appearance it is a closed box. Get more news about Box Panel Explosion Proof,you can vist our website!
When the cable passes through, the cable enters, exits and connects by locking nut, thus effectively avoiding the phenomenon of sparking at the connection. And its housing is usually made of aluminum alloy, which is often painted on its surface in order to make it more fire and corrosion resistant.
Internal structure
The junction box consists of a cover, a box, a terminal block, a diode, a connection wire and a connector. The housing must be highly resistant to aging and ultraviolet light and meet the requirements of harsh outdoor environmental conditions. The self-locking function makes the connection method more convenient and solid. The connection terminals must be firmly mounted and have good solderability to the bus. The connectors, connecting wires have good insulation properties, and the self-locking male and female plugs make the solar panels and electrical connections more convenient and reliable.
Performance characteristics
1、Explosion-proof grade, can be used safely in a variety of flammable and explosive hazardous places. Adopt high-intensity gas discharge lamp as the light source, high light efficiency, long life, the average life of more than 10000 hours.
2、Transparent parts are optimally designed with soft light, uniform illumination and no ghosting, effectively avoiding the operator's eye discomfort and fatigue.
3、Shell is made of light alloy material and high-tech spraying treatment, wear-resistant, corrosion-resistant, waterproof, dustproof, can be used for a long time in outdoor.
4, exquisite structure design, good heat dissipation performance, effectively reduce the temperature of the lamp body, increasing the service life of the lamp. It has good electromagnetic compatibility, will not cause interference to the surrounding environment.
5, light weight, small size, compact and beautiful, simple and convenient operation.
Explosion-proof junction box function
Explosion-proof junction box is usually made of cast metal. Its function is to work in an explosive gas environment, even if the box has circuit sparks, or some explosive gas infiltration, in the role of sparks will occur in a small range of deflagration, and the box can withstand, this situation can prevent the junction box internal short circuit caused by sparks on the site of the dangerous area.
Explosion-proof junction box assembly with relatively high requirements for surface finish at the same time the width of the joint surface has strict dimensional requirements, all leads inside and outside the separation of strict sealing size requirements. The electrical sparks inside the junction box will not affect the external combustible and explosive materials to burn and explode.
Wiring requirements
Use explosion-proof junction box products customers should know that explosion-proof junction box internal terminal, so you wiring to use the terminal, to use the terminal, whether there are specific wiring requirements?
Explosion-proof junction boxes are typically used for lighting threaded connections in explosion-proof areas. Some customers remove the internal terminals and do not use them, wrapping the cable and cable directly with insulating tape for insulation. Usually, it is the internal terminals that are used for wiring. If a terminal is used, the key is to tighten it. Using insulation tape instead of terminals, the tape may fall off after days of spring, summer, and winter, causing short circuit accidents.
