60KA Industrial Power Type 1+2 Surge Protection For Power supplies
OBV5-B60
The combination lightning current and surge arrestors OBV5-B60 meet the type 1+2 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current. If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary. In addition, the QR code printed on the arrestor allows direct access to the online installation instructions.
1.High energy surge protection
2.Remote alarm interface
3.Failure detection indicator
4.Standard modular installation
G2060MT: The power line blocks the total power disribution cabinet of the nuildings that are embedded in the ground.
A distribution box with an outside entry and exit line in the building.
Outdoor distribution cabinet/distribution box.

Transient voltage surgesin lv power lines
Transient overvoltages are voltage surges that can reach tens
ofkilovolts with a duration of the order of microseconds.Despite
theirshort duration, the high energy content can cause serious
problemsto equipment connected to the line, from premature aging to
destruction, causing disruptions to service and financial
loss.Thistype of surge can have various different causes, including
atmospheric lightning directly striking the external
protection(lightning rods) on a building or transmission line or
the associatedinduction of electromagnetic fields on metallic
conductors.
Outdoor and longer lines are the most exposed to these fields,which
often receive high levels of induction.
It is also common for non-weather phenomena, such as
transformer centre switching or the disconnection of motors orother
inductive loads to cause voltage spikes in adjacent lines.
