Dimension:
10/350 25kA SPD 1 Phase Power Lightning Protector Characteristic:
- Class I / B, Type 1 surge arresters.
- This model designed in modular with excellent airtight property.
- 2P, 1 phases
- It is with 35mm electrical lead rail, which make it easy for installation.
- Iimp 25kA.
- It also has the advantage of low residual voltage, quick response, high discharge capability, long life, completed variety, easy maintenance and so on.
- Low residual voltage and quick response.
- Reliable control thanks to Thermo Dynamic Control disconnector.
- Fault indication via red mark in the inspection window.
10/350 25kA SPD 1 Phase Power Lightning Protector Application:
• AC surge protector for low-voltage power system.
• BR-25GR series surge protective devices are usually installed in low voltage main distribution box connected to the incoming end of the buildings.
• Used in the lightning protection zones concept at boundary LPZ0B-LPZ1.
• This product is especially suitable for application in the A grade Lightning Protection in high risk area of lightning strike.
Installation:
• Type 1 or Type 1+2 SPD (Iimp ≥ 12.5 kA) compulsory at the installation source (main distribution board in secondary buildings).
• Installations more than 10 m high (apartment buildings, office buildings, hotels, etc): type 2 SPD recommended for protecting private areas and floor distributors (communal areas) in addition to a type 1 or type 1+2 SPDs.
• Installations with numerous private areas (apartment buildings, office buildings, etc): type 2 SPD where In ≥ 5 kA compulsory at the source of each private area if the type 1 or type 1+2 SPDs cannot be installed at the installation source.
SPDs type 1:
The Type 1 SPD is recommended in the specific case of service-sector and industrial buildings, protected by a lightning protection system or a meshed cage. It protects electrical installations against direct lightning strokes. It can discharge the back-current from lightning spreading from the earth conductor to the network conductors. Type 1 SPD is characterized by a 10/350 µs current wave.
Appliances require external surge protection devices, as their built in protections are usually incapable of withstanding extreme surge events.
The spark gap based type 1 + 2 surge protection device provides a discharge capacity of 25 kA per path with low residual voltages.
Building surge protection protects electric / electronic systems and devices from damage caused by excessively high voltages.
