4 Pole Three Phase Class C Supply 70KA Industrial Lightning Protection Voltage Arrester
Class C Supply 70KA Industrial Lightning Protection Feature:
• 40 kA up to 70 kA protection.
• Visual status display
• The Class C series of over-voltage surge protective devices has been developed to protect against the effects of indirect lightning discharges and induced voltages and is intended to provide protection in zones 1 2 per IEC 62305.
• Labeled connections
• Type 2 (class II/C) for main boards, distribution boards and consumer units.
• Available with and without remote signalling contacts.
• 1 pole up to 4 poles protected.
• BR-70 consists of a high performance varistor block with thermal disconnection device. The plug-in module/base design facilitates replacement of a failed module in situ without the need to remove system wiring.
• Solutions to meet IEC 61643-1 and EN 61643-11

Dimension:
Class C Supply 70KA Industrial Lightning Protection Product Description:
• The combination lightning current and surge arrestors BR-70 meet the type 2 requirement class according to IEC 61643-11.
• These devices protect low-voltage consumer systems from overvoltage 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.
• Available with optional remote signalling
• Usable in systems with lightning protection class 2
Class C Supply 70KA Industrial Lightning Protection Advantage:
1. CE, TUV, CB, ISO9001 Certificates
2. More than 17 years, manufacture experience
3. 90% of our products are exported to Europe, South America, Africa and Asian other countries.
4. Strong technological capacity, advanced production testing equipment.
Use of attention:
1. The PE line of the lightning arrester must be reliably connected with the ground wire of the lightning protection system, and the connection line is short, thick and straight.
2. After correct installation, it can work steadily for a long time. If it is found that the transmission performance of the system is reduced or the signal is interrupted due to the cause of surge protection, it should be maintained or replaced in time.
Packing&Shipping:
Our products will be packed as follow: Box inside, carton outside.
Shipping: By sea, by air or by express up to customer
