Tramontina's electrical materials factory is expanding the line of DPS (Surge Protective Device) – the component responsible for protection against atmospheric discharges.
Tramontina's DPS TDS line is available in 15 kA, 20 kA, 45 kA, 60 kA and 90 kA versions, all with operating voltages of up to 275V and suitable for installation on 127V or 220V networks.
The new models are available in classes 1 – for areas highly exposed to atmospheric discharges – and 2 - for indirect atmospheric discharges, that is, those that occur close to the building area or electrical networks.
They all have a green front indicator, which changes to red to indicate when it should be replaced during installation.
The engineering team at the Tramontina electrical materials factory highlights that the DPS has the function of protecting electronic equipment from atmospheric discharges and blackouts and instabilities in the electrical network, preventing the on-off, which usually occurs in these incidents, from burning the gadgets.
The equipment detects the occurrence of short-term transient overvoltages in the electrical network and diverts the surge currents to earth.
Overvoltages circulate through three distinct paths: electrical network, telephone line and TV antenna circuit. Hence the importance of protection at the three entrances.
The DPS must interact with the grounding system, to complete safety and protect people against electrical discharges, as well as buildings and electronic devices.
The device's action is not only for atmospheric discharges (lightning), but also for overvoltages and instabilities in energy utility networks.
The equipment must be installed in accordance with the requirements of Standard NBR 5410 for low voltage electrical installations, in order to guarantee the safety of people and animals, the proper functioning of the installations and the conservation of assets.
