Reliably protect DC applications against surge voltages

The goal of the All Electric Society is a world in which sufficient energy is available from renewable resources. Electrification is the first step towards achieving this. The new VAL-MB-T2-750DC and VAL-MB-T2-1000DC type 2 surge protective devices from Phoenix Contact provide support here.

As the number of DC applications continues to increase, more and more system operators are also using direct current with 650 to 750 V DC in industrial applications. In addition to electromobility, direct current is also used for battery storage systems. These systems lose valuable energy if they first have to convert the energy fed in from wind turbine generators or photovoltaic systems.

Applications with direct current also require reliable protection against surge voltages caused by lightning currents or even switching operations. The surge protective devices specifically developed for these applications provide reliable protection at high voltages. Depending on the system voltage, a suitable solution is available for various applications in the form of these two versions: VAL-MB-T2-750DC and VAL-MB-T2-1000DC. They can be used at altitudes up to 6,000 m above mean sea level. A mechanical/visual status indicator provides information about the status of the protective device. The integrated remote signaling also enables integration into the control room. The compact space-saving design is thus suitable for installation in confined spaces.
