e. Weidmüller’s stainless steel terminal rails have the following composition: CrNi 18-10 stainless steel (i. soft metal, Weidmüller’s terminal rails are 2. According VDE 0100 part 540, for conductors with cross-sectional areas exceeding 10 mm2 , both protective and neutral conductors may be grouped together single category conductors designated PEN. Terminal rails are made either steel, stainless steel, aluminium, copper plastic, depending the area of application.3 thick. Aluminium Aluminium second only copper its electrical conductivity. this chapter, you will find range terminal rails and profile rails for component installation, together with end brackets for holding and isolating the components. Copper Copper, heavy metal, has the best electrical conductivity of all metals used.Terminal rails Introduction Active and passive components, well intelligent modules, are mounted terminal rails. Among metal DIN rails, has the lowest short-circuit resistance, similar stainless steel. Steel The steel rail the most widely used DIN rail the market. Weidmüller earth terminals the W-Series, Z-Series, I-Series, SAK- and AKZ-Series comply with requirements stipulated IEC 947-7-2. If terminal rail used PEN busbar, the following criteria must observed: • Only E-Cu aluminium profiles are allowed • Short-circuit currents and thermal rated currents must be taken into account • The terminal rails are insulated contribution to protective insulation Stainless steel Stainless steel collective noun for all kinds steel (alloys) which are smelted special process and have a high degree purity. However, only after the use certain consumables which are frequently not taken into consideration that electrical installation finally completed. Terminal rail systems F Accessories F. Aluminium oxidises quickly air; thus passivated, offers excellent corrosion protection. Weidmüller supplies components which show perfect functional compatibility.8 1282250000 2012/2013 . Stainless steel has much-enhanced resistance corrosion. This leads its use special applications where, for example, clearance and creepage distances with respect the mounting plate cannot achieved with the standard terminal rails. Plastic The plastic terminal rail scores two counts: firstly, its insulating properties, and secondly, its low weight. This method has proved highly effective for decades. They can also used protective conductor busbar. ∼18 chromium, ∼10 nickel). These guarantee firm installation and isolation. One advantage its light weight
