Dimension:
40ka 4P SPD AC Type 2 Surge Protective Device Application:
• BR-40 4P AC SPD is suitably used in the TN-S power supply system
of AC 50/60HZ.
• Suitable for system power protection, such as power distribution
cabinet, switch cabinet, switch cabinet, AC distribution board,
etc.
• To protect from direct and indirect lightning impulse and other
transient over voltage.
Installation:
• 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.
