Dimension:
AC Surge Arrester 40kA Type 2 Surge Protection Device Application:
• Applicable to discharge overvoltage occurred by switch-type
(8/20µs) over currents.
• BR-40 4 pole surge arrester is suitable for TN-S system.
• Used for lightning and overvoltage protection in AC50/60Hz,
protect the low voltage power network from lightning or surge over
votlage.
• Designed for installations where direct lightning strike risk is
reduced (without LPS or medium risk)
• Also used in addition to the SPD type 1 in order to limit the
operating voltage arresters
AC Surge Arrester 40kA Type 2 Surge Protection Device Advantage:
• High discharge current.
• Voltage protection level (Up) is low
• Interchangeable modules varistors
• IP20 protection
• Incorporate technology-based high energy varistors
SPD type 2 installation guide:
• The type 2 arresters must install into sub-distribution boards
after main distribution boards containing type 1 arresters.
• For proper operation between type 1 and type 2 arresters at least
10- 15 m cable or wire must be otherwise a decoupling coil have to
install between the two devices.
• In areas where storms are frequent, it is strongly recommended to
install additional protection systems.
We can provide products with the same parameters as dehn spd type
2.
