Our unique features
ZOTUP brings to the market a new technology developed in 4.5 years of intense research and development, supported by over 360 laboratory tests and protected with 5 international patents. It actually constitutes the new state of the art in the protections from overvoltage for low voltage power circuits.
ZOTUP overall protections represent an absolute novelty on the market: high performance, safety, simplicity of installation and reliability. Now all these qualities are available in a single product. The ZOTUP services are at the top in the various trial classes of the unloaders, but to make this family of unloaders unique are our unique characteristics.

Fuse Function
Watch VideoThe Fuse Function (ff) ensures that, in the event of the surge protector reaching its end of life, it fails in an open circuit mode without the need for series-connected backup fuses. By eliminating fuses with MCB ≤ 160 A and their respective fuse connection cables, it improves the overall level of protection and reduces the foot print requirements within the panel. The internal disconnector, a patented element of ZOTUP, not only disconnects the two end-of-life processes (slow and instantaneous, as defined by the IEC 61643-1 standard) but also provides an Integrated Fuse Function (ff). This allows the SPD to maintain its full discharge capacity and reduces the overall voltage drop (Upf) across the protection circuit.

Progressive Performance Indicator
Watch VideoThe progressive performance indicator allows the monitoring of the SPD degradation level locally, through the progressive performance status indicator, and remotely, via a remote signalling contact (whether available) that activates when the minimum performance is reached. The level of degradation is displayed through color changes (green-yellow-red) in the status display window. The transition from the initial green color (full performance) to completely yellow (minimum performance) occurs progressively. This shift provides advanced information about the end of life of the SPD, enabling timely maintenance and replacement.

Pollution Degree 3
Watch VideoThanks to intensive research in materials and a specifically oriented design, ZOTUP SPDs achieve and satisfy Pollution Degree 3 requirements, with voltages up to 500 V AC and an extended temperature range (-40°C to +80°C). ZOTUP SPDs can be used even in particularly harsh environments with conductive pollution such as dust, salt spray, humidity, and condensation. In the presence of conductive pollution, SPDs can suffer severe damage, even without surges. This feature not only ensures greater reliability but also undeniable suitability for applications that cannot be satisfied with lower Pollution Degrees or normal temperature ranges.

High Withstanding Capacity Against Temporary Surges
A surge protection device is designed to shield against high-frequency events lasting microseconds (kHz-MHz). Often underestimated, the faults that occur at 50 Hz, commonly referred to as Temporary Overvoltages or Industrial Frequency Overvoltages (f = 50 Hz), are particulary dangerous, they have a relatively long duration and are non-impulsive in nature. The SPD is a device that has to assure the Withstand Mode (W), being able to withstand TOVs without being damaged. Some SPDs are also characterized by Safe Failure Mode (S): the SPD fails but does so safely (without catching fire and maintaining its IP rating). The latter is the minimum accepted condition.
