3 Pole SPD T2 Power Surge Protection Device For Low Voltage
OBV10-I-15
Heavy duty AC Surge Protection Device (SPD) for high risk, low tolerance electrical service entrance applications. The OBV10-I-15 provides protection against the direct and indirect effects of lightning and is particularly useful in a high lightning area where the risk of heavy surge current or even direct strike is high, i.e. buildings equipped with lightning rods.
Surge protectors OBV10-I-15 meet the type 1 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 voltage-limiting,high-performance spark gaps provide several benefits.A short response time, a low protection level and high current leakage capability with long service life.
* Connectable lightning current and surge arrestors
* High arresting capacity up to 15 kA (10/350μs) per pole
* Combination arrestors for buildings with lightning protection system
* Simple standard hat rail mounting
* Labelled connections
* Usable in systems with lightning protection class 1-4

Note: The system lightning protection does not guarantee that the equipment will not be 100% damaged by lightning; the power system must be multi-level lightning protection;
The complete lightning protection system includes external lightning protection and internal lightning protection. External lightning protection refers to: lightning receptors, down conductors, and grounding bodies, which are mainly used to defend against direct lightning strikes. Internal lightning protection includes: shielding, reasonable wiring, safe distance, equipotential connection, overvoltage protection, etc., mainly used to prevent lightning induction, ground potential counterattack, lightning wave intrusion, etc.

Tip:How can we distinguish the quality of the lightning arrester?
1. It can be seen from the reaction time: determine whether the lightning arrester can respond in time and quickly discharge the lightning current.
2. It can be seen from the insertion loss: this refers to the installation of a lightning protector, the impact of this lightning protector on the line, the smaller the better
3. It can be seen from the number of impact resistance: determines the service life of the lightning arrester. Generally, the gas discharge tube will not drop after being placed for a period of time. If you want to check its quality, you can use an adjustable high-voltage DC power supply to test .
What skills should lightning protectors have in the selection?
1.Confirm power supply system
First of all, you must determine what your power distribution system is like, whether it is TT, TN or IT system. After determining the power distribution system, you can choose the protection mode and wiring method of the lightning arrester to select the appropriate lightning arrester.
For example, TN-C uses 3P lightning protection device, TN-S uses 4P, TT uses 3P+N, etc.
2.Know the main parameters of the lightning arrester.
