Component: HVL 120-0.3


For DC systems.


For public safety and equipment protection.


EN 50 122-1/EN 50123-5


The low voltage limiter HVL consists of a metal oxide varistor and two thyristors in antiparallel connection.


Short-time overvoltages with a duration of less than 0.4 ms are limited by the metal oxide resistor. Due to the thyristors voltages with a duration of 0.4 ms or more are limited to 3 V.


The maximum voltage in accordance with EN 50123-5, table 5.2, can be reduced or increased on request as the case arises.


Including fittings (tee and angle).

For DC systems (indoor and outdoor installation)


silicone rubber casing.


Fadenlänge: 176 mm

For rail fastening.


Including earth wire 50 mm².


Material body/ shackle: G-CuSn

For DC and AC overhead contact line systems, with cast resin insulator, cast iron cap and copper horns.
