Product information "Surge arrester type 1+2, ETITEC V B T12 280/12.5 4+0 RC, (TN-S) "
The great advantage of the combined arrester is that lightning equipotential bonding and terminal device protection are provided in one device in one protection level. They are suitable for discharging high partial lightning currents and limiting transient overvoltages. The combined arresters have an energetically coordinated protective effect to the equipment within a 10 m cable path. If this is exceeded, further protective measures should be taken. Dangerous sparking and transient overvoltages in the electrical system are prevented, thereby avoiding major damage to property.
Combined arresters T1-T2 are type 1 and type 2 protective devices tested in accordance with the test standard DIN EN 61643-11 (VDE 0675 Part 6-11). Their task is to control high energies, safely divert lightning currents and limit dangerous transient overvoltages to a level that is compatible with the equipment.
In addition, type 1 or combi T1 & T2 surge arresters are also suitable for external lightning protection systems. (External lightning protection)
