of all fires are caused by electricity.
Frankfurt am Main, Germany , March 18, 2018
Light+Building in Frankfurt am Main is the world’s leading trade fair for building technologies – and Siemens will again be exhibiting at this event, which showcases industry trends, ideas and future-fit solutions! From March 18 -23, 2018 the exhibition center in Frankfurt will again be the meeting place for trade visitors from Germany and many other countries.
5SM6 AFD units
About one-third of all fires caused by electricity are attributed to hazardous arcing faults. Particular mention is to be made to serial arcing faults. Residual current protective devices (RCDs) and miniature circuit breakers (MCBs) are not designed to detect and safely disconnect serial arcing faults and do not offer adequate protection in such cases: for example, damaged wire insulations, crushed or broken cables, bent connectors, loose contacts, or even defective electrical devices. The resulting electrical arcing faults can cause cable insulation to ignite, leading to a cable or even building fire.
Siemens closed this safety gap in the IEC market with its AFDDs (Arc Fault Detection Devices). As a supplement to MCBs and RCDs, these protection devices address all types of arcing faults, including serial ones. The AFD unit complete the comprehensive SENTRON portfolio by providing a comprehensive all-round protection of electrical installations. They enable the early prevention of various fire hazards, from the electrical line right through to the end device, protecting human lives, buildings, and assets.
The 5SM6 AFD units are based on the by Siemens patented SIARC detection technology.
The result: intelligent fire prevention and thus optimal and standard-compliant comprehensive protection of people and plants.
Quick, standard-compliant, and error-free configuration and planning thanks to professional software, tender specifications, and comprehensive engineering data.
Flexible implementation of needs-based solutions for electrical installers and panel builders, while simultaneously reducing stock keeping needs – thanks to the modular portfolio offering a broad and comprehensive range of standardized accessories.
Installing new equipment or retrofitting existing systems requires little cost and efforts due to the intuitive installation of AFD units on standardized busbars or mouting rails.
The AFD units can be easily purchased either online or locally from electrical wholesalers.
Technical advisory services on products, applications, and standards as well as personal support for everything from design development to network planning and configuration.
