DIN Rail
A DIN rail is a metal rail of a standard type widely used for mounting circuit breakers and industrial control equipment inside equipment racks. These products are typically made from cold rolled carbon steel sheet with a zinc-plated or chromated bright surface finish. Although metallic, they are meant only for mechanical support and are not used as a busbar to conduct electric current, though they may provide a chassis grounding connection. The term derives from the original specifications published by Deutsches Institut für Normung (DIN) in Germany, which have since been adopted as European (EN) and international (IEC) standards. The original concept was developed and implemented in Germany in 1928, and was elaborated into the present standards in the 1950s. Types There are three major types of DIN rail: * Top hat section (TH), type O, or type Ω, with hat-shaped cross section. * C section * G section Top hat rail IEC/EN 60715 This 35 mm wide rail is widely used to mou ...

Circuit Breaker
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household appliances, to large switchgear designed to protect high voltage circuits feeding an entire city. The generic function of a circuit breaker, or fuse, as an automatic means of removing power from a faulty system, is often abbreviated as OCPD (Over Current Protection Device). Origins An early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses. Its purpose was to pro ...

Printed Circuit Board
A printed circuit board (PCB; also printed wiring board or PWB) is a medium used in Electrical engineering, electrical and electronic engineering to connect electronic components to one another in a controlled manner. It takes the form of a Lamination, laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with an artwork pattern of traces, planes and other features (similar to wires on a flat surface) Chemical milling, etched from one or more sheet layers of copper Lamination, laminated onto and/or between sheet layers of a Insulator (electricity), non-conductive substrate. Electrical components may be fixed to conductive pads on the outer layers in the shape designed to accept the component's terminals, generally by means of soldering, to both electrically connect and mechanically fasten them to it. Another manufacturing process adds Via (electronics), vias: plated-through holes that allow interconnections between layers. ...

Standards Australia
Standards Australia is a standards organisation established in 1922 and is recognised through a Memorandum of Understanding (MoU) with the Australian government as the primary non-government standards development body in Australia. It is a company limited by guarantee. As of 1998, it had 73 members representing groups interested in the development and application of technical standards and related products and services. The MoU recognises Standards Australia as Australia's representative on the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC) and the Pacific Area Standards Congress (PASC). Standards Australia develops internationally aligned Australian standards (AS) and participates in standards-related activities. Standards Australia and Standards New Zealand work together to develop joint standards (AS/NZS). Licensing of the sale of standards In 2003, Standards Australia sold its standards publication business and ...

List Of IEC Standards
This is an incomplete list of standards published by the International Electrotechnical Commission (IEC). The numbers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here. * IEC 60027 Letter symbols to be used in electrical technology * IEC 60028 International standard of resistance for copper * IEC 60034 Rotating electrical machines * IEC 60038 IEC Standard Voltages * IEC 60041 Field acceptance tests to determine the hydraulic performance of hydraulic turbines, storage pumps and pump-turbines * IEC 60044 Instrument transformers * IEC 60045 Steam turbines * IEC 60050 International Electrotechnical Vocabulary * IEC 60051 Direct acting indicating analogue electrical measuring instruments and their accessories * IEC 60052 Voltage measurement by means of standard air gaps * IEC 60055 Paper-insulated metal-sheathed cables for rated ...

International Electrotechnical Commission
The International Electrotechnical Commission (IEC; in French: ''Commission électrotechnique internationale'') is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as "electrotechnology". IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages four global conformity assessment systems that certify whether equipment, system or components conform to its international standards. All electrotechnologies are covered by IEC Standards, including energy production and distribution, electronics, magnetics and electromagnetics, electroacoustics, multimedia, telecommunication and medical technology, as well as associated general disciplines such as t ...

British Standard
British Standards (BS) are the standards produced by the BSI Group which is incorporated under a royal charter and which is formally designated as the national standards body (NSB) for the UK. The BSI Group produces British Standards under the authority of the charter, which lays down as one of the BSI's objectives to: Formally, as stated in a 2002 memorandum of understanding between the BSI and the United Kingdom Government, British Standards are defined as: Products and services which BSI certifies as having met the requirements of specific standards within designated schemes are awarded the Kitemark. History BSI Group began in 1901 as the ''Engineering Standards Committee'', led by James Mansergh, to standardize the number and type of steel sections, in order to make British manufacturers more efficient and competitive. Over time the standards developed to cover many aspects of tangible engineering, and then engineering methodologies including quality systems, safety ...

European Standard
European Standards (abbreviated EN, from the German name ("European Norm")) are technical standards which have been ratified by one of the three European standards organizations: European Committee for Standardization (CEN), European Committee for Electrotechnical Standardization (CENELEC), or European Telecommunications Standards Institute (ETSI). All ENs are designed and created by all interested parties through a transparent, open, and consensual process. European Standards are a key component of the Single European Market. They are crucial in facilitating trade and have high visibility among manufacturers inside and outside the European territory. A standard represents a model specification, a technical solution against which a market can trade. European Standards must be transposed into a national standard in all EU member states. This guarantees that a manufacturer has easier access to the market of all these European countries when applying European Standards. Member count ...
