Vertical three pole fuse switches for fuses NH00 size.
Depending on the type of model, this range of fuse switches offers the option of one pole disconnection, allowing individual disconnection of each phase or the three pole disconnection, disconnecting all three phases simultaneously.
D0 fuse-links are used as the most reliable protection of electrical installation, control and signal circuits against overload and short-circuit currents. The whole system D0 contains a complete range of three physical sizes D01, D02 and D03 fuse-links, standard ceramic and new plastic bases, fuse disconnectors and all necessary accessories.
D fuse-links for use by unskilled persons for domestic and similar applications are used as the most reliable protection of electrical installation, control, and signal circuits against overload and short-circuit currents. The whole system D contains a complete range of five physical sizes DI, DII, DIII, DIV, and DV fuse-links, standard ceramic and new plastic fuse bases, and all necessary accessories.
Pronutec includes in its range of ETI cylindrical fuses and fuse bases for cylindrical fuses.
Cylindrical fuse-links are used as the most secure protection of electrical installations, control, and signal circuits against overloads and short circuit currents. Their dimensions comply with IEC 60269-1 and IEC 60269-2-1. They are used mainly in industrial areas since their dimensions allow voltages of up to 690 V.
The most common sizes are the following four: 8×32, 10×38, 14×51, and 22×58.
It works by sinking energy from a live network, by connecting a load at the LV side of an MV/LV transformer, and detecting the current that is produced at he MV side of the transformer.
The Ariadna CI-TX unit acts as the signal transmitter that sinks energy from the electric grid, producing coded current pulses, and the Ariadna CI-RX unit as the digitally tuned receiver that detects them.
In a similar way to MV live cable identification, it is possible to identify LV energized cables by sinking current from the network.
CI-TX transmitter is connected at the end side of the LV cable to be identified. When turned on, it starts to sink current pulses from the network, and these pulses flow from the point of injection to the LV transformer that feeds it.
With the CI-RX unit it is possible to identify LV cable path in any accessible places, like manholes, busbars, etc.
Through polarized frequency signal injection and detection, it is posible to positively identify de-energized cables.
Unlike live cable identification, the needed energy for generating identification signals come from Ariadna CI-TX´s rechargeable Li-Ion battery, instead of coming from the grid.
Two ways are available for injecting signals on cables, through direct connection or by using a toroidal inductive clamp.
Afterwards cables are identified by measuring produced signal´s amplitude and polarity.

Ariadna CI detects medium and low-voltage cables (energized or de-energized), and complies with the following safety standards:
– Electromagnetic compatibility: EN 61000-6-3, EN 61000-6-2.
– Electrical safety: EN 61010-1 CAT IV 300 V. Protection against electric shock. Class II.
There are many situations in which it is necessary to quickly and accurately identify live Low Voltage (LV) cables, for example, when opening a trench, making a branch in a line, before carrying out some maintenance tasks, when making a new connection, …
Merytronic has developed the Ariadna IC2G, an ultra-portable Cable identifier device which is used for positive cable identification, in Low Voltage cables.
The device consists of a transmitter (IC2G-TX) and a receiver (IC2G-RX). Its use is simple: the transmitter (TX) is connected to an LV cable and the receiver (RX) is used to identify or locate that cable upstream, towards the MV/LV transformer.
In maintenance tasks in LV networks, it may be necessary to know the route of electric cables.
Merytronic has developed a solution that allows a pre-location of the cable route with voltage upstream, in a quick and easy way, by simply connecting a T-sensor to the IC2G device.
