Choosing the right arrester is as fundamental as it is challenging. ZOTUP, a leader in the production of SPD, constantly supports wholesalers and installers.

ZOTUP Srl, leader in production of surge arresters, reaches the fourth year since the market launch of its new range of surge arresters, based on technology developed in four and a half years of research and development and supported by over 330 laboratory tests. The company, which is based in Bergamo and produces entirely in Italy, has always been characterized by its constant proximity to its market interlocutors. «Support and constant coaching are an integral part of our activities, and fundamental for choosing the right product. Wholesalers and installers are never left alone. Training, updating and support, in fact, cannot be missing when talking about overvoltages and protections in systems. For this reason the ZOTUP technical team is always available to assist in the right choice of product, providing constant support through telephone consultancy, inspections, technical courses and refresher courses", explains Andrea D'Ippolito, of the Sales and Marketing Department of ZOTUP.</strong >

How much is Is training strategic, based on dialogue with commercial partners and the installer?

«Training and updating are fundamental when it comes to overvoltages and protections in systems. For this reason,ZOTUPoffers various training tools. The purpose is obtain not only maximum protection against atmospheric discharges and overvoltages, but also develop and consolidate the training of installers, distributors, designers and partners in the sector. TheZOTUP ACADEMYprovides not only technical training seminars for experts and engineers, but also days at the counter and technical training courses at distributors. The training meetings are organized in collaboration with the wholesaler and dedicated to the internal sales force, or also aimed at end customers. These are excellent opportunities not only to delve deeper into the topic of overvoltages and types of arresters, but also to discover current promotions, as well as to stay up to date with current regulations in the sector (see for example the new CEI 64-8; V5).

Digital technology has now revolutionized the relationship between companies and consumers. How do you use it to communicate to the installer?

«Digital is has now become the primary communication channel. Requesting information or quotes, downloading catalogs and technical sheets, signing up for a technical meeting are activities which inZOTUP happen very quickly thanks to digital. From today, even the choice of the right surge arrester takes place digitally. On the occasion of the recent publication of the new CEI 64-8 standard; V5, which effectively makes it “mandatory” the adoption of SPD, the company has launched theWebapp ZOTUP, downloadable for free from the page webapp.zotup.it, via QR Code, as well as directly from the Services/Download section of the site zotup.com.< /strong> Completely free, the app allows installers and distributors to independently identify the most suitable SPD suitable for the protection needs of different systems."

How exactly does it work?

«Choosing the right arrester is as fundamental as it is demanding. There are many parameters to evaluate to identify the right protection solution: the identification of the energy distribution system, the area in which it is location of the system, the position of the panel, all in compliance with current regulations. Using the Webapp requires simple registration: it will be It is necessary to register only on the first login to then be able to save the app directly on the screen of your smartphone or on the desktop of your PC. Once logged in, you are done. guided in choosing the arrester through simple multiple choice questions: in a few seconds you can so identify the SPD suitable for your protection needs. The Webapp allows you to view all the useful information about the product: it is It is also possible to view and download the technical data sheet and assembly instructions. Once an SPD has been identified (and a panel protected), it is It is possible to move directly to the next frame, gradually saving the results obtained. This is how you get a handy “list” of products for your own sizing, which you can send via email or with which you can go directly to the distributor for purchase."

What other digital resources do you offer to wholesalers and end customers?

«Among the digital communication tools we remember the company website www.zotup. com, from which you can consult news on promotions and events. &` Furthermore, it is possible to download constantly updated technical material, such as a catalogue, applications manual, technical data sheets and price lists. There is no shortage of communications through social networks and newsletters, to always stay up to date on news of products, promotions and training events."

In a general perspective, what types of products and/or services will the activities focus on? of 2020?

«The activities of 2020 are focused first and foremost on promoting the new range of arresters. In particular, the product catalog is enriched with 4 new surge arresters: codes 202 220 L 2/10 230 ff 2 TT and 202 240 L 2/10 230 ff 4 TT, and the respective with remote signaling contact 212 220 L 2/10 230 t ff 2 TT and 212 240 L 2/10 230 t ff 4 TT. Alongside the new products, another activity main event of the new year will be focused on the constant improvement of the sales and after-sales assistance service, as well as the organization of new training sessions for wholesalers, installers and designers."

What objectives do you intend to share with the electrical material distributor?

«Our main objective is that of providing the distributor and the end customer with the right product. &` It is essential, in fact, to understand the customer's real protection needs and respond with the most suitable surge arrester. suitable. For this reason, the close collaboration between company and distributor is fundamental, in order to be able to give a concrete and effective response to customer needs."

SPD FOR SENSITIVE EQUIPMENT IN TT SYSTEMS

Code ZOTUP 202 220: model L 2/10 230 ff 2 TT. 

Pre-assembled bipolar, limiting surge arrester. &` typically installed in secondary distribution panels (SQBT) in 230 V single-phase circuits, both in TT systems downstream of the RCD differential switch, and in TN systems, presenting a notable level of protection (Up < 1kV at 5kA of In 8 /20 μs) achieved thanks to the possibility to be able to use the CT1 (2+0) type connection according to the HD 60364-5-534 standard. This arrester is also available with remote remote signaling contact (model L 2/10 230 t ff 2 TT), with code 212 220.

Code ZOTUP 202 240: model L 2/10 230 ff 4 TT. 

It is the three-phase version is more neutral of the previous model. For this model too it is the version with remote remote signaling contact is available: model L 2/10 230 t ff 4 TT, with code 212 240.

Both products have the peculiarity of to possessa high resistance to TOV (temporary overvoltages), as reported below:

•     between L-PE UT equal to 440 V/120 min (withstand failure mode: W) and 1455 V/200 ms (safe failure mode: S)
•     between N-PE UT equal to 1200 V/200 ms (withstand failure mode: W).

These are the main features of the 4 new ZOTUP dischargers:

1. Classification for the impulse test: Test class II/Type 2 (according to IEC/EN 61643-11) with rated discharge current (8/20 μs) In = 10 kA;
2. Protection level Up < 1 kV at 5 kA of In 8/20 μs;
3. Unrequired overcurrent limitation with line CB ≤ 160 A o for Isccr ≤ 5 kA eff (Integrated Fuse Function – ff);
4. Three-level colored status indicator with progressive indication of residual performance;
5. Resistance to harsh environments (pollution degree 3).
