Surge Protector BR-25GR 25KA 2P Application:
• Suitable for 50/60Hz ac system
• Widely used in mobile communication base stations, microwave
communication bureaus/stations, telecommunication rooms, industrial
mining, civil aviation, financial securities and other power
systems.
• Used to suppress transient overvoltage, discharge surge energy,
so as to protect the system circuit and equipment.
• Against surges at direct lightning stroke (in presence of
lightning conductor)and against indirect surges on the electrical
networks.
Surge Protector BR-25GR 25KA 2P Advantage:
• High flame retardant, anti-corrosion.
• Reliable quality and long service life.
• Large discharge energy.
• High protection level.
Surge Protector BR-25GR 25KA 2P 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.
Our product same as the L&T SPD device offers reliable
protection against power surges caused by lightning strikes or
electrical faults.
Class B SPD: Two-pole arrester in the specification class B for the
protection of electrical consumer installations and equipment in
case of overvoltage or direct lightning strikes.
Electrical spd meaning: Surge Protective Devices (SPD) are used to
protect the electrical installation, which consists of the consumer
unit, wiring and accessories, from electrical power surges known as
transient overvoltages.
