Fuse Terminal Blocks Fuse-holder terminals for cylindrical fuses up to 1,000 V DC Fuse solutions for PV strings In order to achieve higher system voltages, single panels are connected in series during the installation of photovoltaic panels forming so-called “strings”. For this application Weidmüller offers terminals resisting a particular insulation test. This makes sure that the terminals permanently resist a voltage of 1,000 V DC under any climatic conditions. Weidmüller provides fuse carriers for the proven cylindrical 10.3 mm x 38 mm (13/32“ x 1.5“) fuses that are suitable for mounting on DIN rails. They are compact, protected against accidental contact and in compliance with the requirements of the IEC. Convenient change of the fuse The pivoting release lever allows a quick, safe and reliable change of the fuse. Long-proven screw connection technology The W-series is the best choice for all applications requiring solid connections and safe contacts. 86 Fuse Terminal Blocks Protected against excessive heating The ventilated housing reduces internal heating thus extending the durability of the fuse.

This is related to the fact that the performance of the system should be maximised, but with the minimum amount of current. This means that the voltage is raised. In the past, manufacturers of terminal blocks have concentrated on the clearance and creepage distances above all to determine the rating data. Weidmüller has changed its behaviour. According to our internal standards, we perform an AC partial discharge test on all terminal blocks. Now we do the same for DC voltages, which gives us a unique characteristic in the terminal block market. Guaranteed easy marking All accessories, as well as all terminal blocks, can be easily marked at a high quality. In this way you can always have an overview of the system and it speeds up any measurements or troubleshooting. Optical isolation and increasing the insulation distance The extensive range of end brackets with different shapes and colours ensures more orientation and safety in your system. 90 Feed-through terminals Potential blocks for string collection If terminal blocks are grouped into blocks of equal potential, there is a requirement that the voltage is isolated from the terminal to the mounting rail. Only at the transition from - to + does the terminal need to isolate the system voltage from the mounting rail and also from the neighbouring terminal (assuming no additional separation is used). Weidmüller presents a tailored solution for your particular application.

In contrast to copper, aluminium exhibits certain characteristics that must be taken into account when using this material as a conductor in electrical engineering. A thin, non-conductive layer of oxide forms immediately on the unprotected surface of the aluminium as soon as it is exposed to the air. This layer increases the contact resistance between the aluminium conductor and the current bar of the modular terminal. And that, in unfavourable conditions, can lead to poor contact. And in stranded conductors the contact resistances of the individual strands are added together. Despite these disadvantages, aluminium conductors can be connected to Weidmüller modular terminals, provided the reduced rated currents for aluminium conductors and the following installation conditions are adhered to. 1.Scrape the stripped end of the conduc- tor carefully, eg. with a knife, to remove the layer of oxide. Caution: Do not use brushes, files or emery paper because particles of aluminium can be deposited on other conductors. 2.After removing the layer of oxide, coat the end of the conductor immediately with a neutral grease, e.g. acid- and alkali-free Vaseline, and connect it to the terminal immediately. 3.Repeat the above procedure if at any time the conductor is disconnected and reconnected. 4.The above installation instructions are valid for solid round or sector aluminium conductors only. 114 Solid round and sector conductors Terminal type Rated cross-section W-Series WDU 4 WDU 6 WDU 10 WDU 16 WDU 35 WDU 70 WDU 120 WDU 240 Reduced rated current when connecting an aluminium conductor Clamping screw thread size Tightening torque mm2 4 6 10 16 35 70 120 240 „A“ 27 35 48 64 105 163 230 – M3 M 3.5 M4 M5 M6 M8 M 10 M 10 Nm 0.6 – 1.0 1.2 – 1.6 2.0 – 2.4 3.0 – 4.0 4.0 – 6.0 10.0 – 12.0 15.0 – 20.0 12.0 – 20.0 35 70 120 185 300 105 163 230 300 409 M6 M8 M 10 M 12 M 16 3.0 – 6.0 6.0 – 12.0 10.0 – 20.0 15.5 – 31.0 30.0 – 60.0 Stranded conductors W-Series WFF 35 WFF 70 WFF 120 WFF 185 WFF 300 Installation advice when using flat cable lugs When tightening the terminal it is advisable to hold the conductor to prevent deformation of the terminal rail and to avoid twisting the foot of the terminal. When connecting stranded aluminium conductors to modular terminals, it is advisable to use an aluminium cable lug chosen to match the type of conductor and connected according to the instructions of the cable lug manufacturer. It is necessary to fit a copper-plated aluminium washer between the aluminium cable lug and the copper current bar of the modular terminal. This is the only way of guaranteeing a reliable transition between the copper and the aluminium. Fit the washer in such a way that the copper side is in contact with the current bar, and the aluminium side in contact with the cable lug.
