LOW-VOLTAGE SURGE PROTECTION DEVICES: PROTECT YOUR INSTALLATIONS WITH ZOTUP

Although low voltage is less dangerous than high voltage, when dealing with overvoltages you must always take the right precautions. The so-called surge protection devices or SPDs (surge protection devices) come to our aid in this field. Zotup'slow voltage surge arrestersare a high qualityMade in Italyproduction. and are able to effectively protect systems and people.

What is it? a low voltage arrester

By definition, the term “low voltage” indicates arangeof voltage between 50 and 100 V in alternating current (ac) and from 120 to 150 V in direct current (dc). Since low voltage is Widely used in the private, commercial and industrial sectors, it is It is possible to find it practically everywhere and, therefore, protecting yourself in case of overvoltages becomes necessary.

Overvoltages 

The main objective of a surge arrester (or SPD) is to to protect the system from so-called "voltage peaks". For “voltage peaks” means a level of electrical voltage higher than that of normal operation within an installation, circuit or system.
There are multiple causes that give rise to overvoltages. At a theoretical level, they are divided into two categories: overvoltages of internal origin and those of external origin; the former are caused by sudden variations in the configuration of the electrical circuit while the latter are the result of phenomena that originate outside the system such as, for example, lightning.
surge arrestersare the only way to protect yourself from voltage spikes as they have the ability to store and divert excessive current flows. Also called voltage limiters, according to the EN 61643-11 (2012-10) standard, they are generally divided into three types:

Type I: ideal for areas where adverse meteorological phenomena such as violent storms and lightning frequently occur;
Type II: complementary to first type and capable of supporting overvoltages caused by maintenance work on the power line;
Type III: to be installed following the first two variants directly on the back of the socket of an appliance to guarantee protection additional.

Low voltage surge arresters

The Zotup catalog presents a wide range of low voltage arresters. The three types of SPD mentioned above they protect systems and people against:

• direct and indirect lightning effects (type I and II);
• indirect lightning effects (type II);
• induced overvoltages (type III).

Especially when it comes toData Center protection, it is It is necessary to uselow voltage surge arresters with additional mains filter, in order to attenuate conducted electromagnetic disturbances.
Subdivision aside, all Zotup SPDs have three common characteristicsthat make them ultra-competitive on the market:

• Integrated Fuse Fusion (ff):Zotup SPDs have an internal, combined and patented backflow preventer that maintains full capacity. discharge and reduces the overall voltage drop, as well as costs and dimensions;
• Three-color (green-yellow-red) progress indicator showing the remaining performance of the arrester:&nbsp ;appliance maintenance is simplified and replacement planning is facilitated during periodic checks and checks;
• Zotup SPDs are designed to resistPollution Degree 3pollution, making them suitable to a wide range of applications, including those in locations with harsher environmental conditions. severe (pollution, saltiness, humidity...).

Zotup: experts in surge arresters

Established in 1986, Zotup is leader in the surge arrester sector. With 100% Italian production, the Bergamo company offers high quality products able to guarantee total safety for its customers, their goods and their working environment. Over the years it has continued to innovate both its products, as demonstrated by the new Zotup surge technology, and its services, for example with the creation of the Zotup Academy. Beyond of the relevant sector (public, corporate or private), Zotup provides a technical support service always ready to satisfy the customer's needs and to follow him from the moment of the initial choice with inspections and measurements, up to the maintenance of the product already completed. installed. Whatever the customer needs, he knows he can do it. rely on the experience and reliability by Zotup for surge protection to make him feel truly protected.
