Indication window for clear display of SPD status.
BR-40DP series surge arrester is installed between LPZ1 and LPZ2, it can provide type 3 protection for equipment which installed within 5 meters from these devices.
Application:
Protect commercial and industrial installations
Protect commercial and industrial installations in their secondary distribution boards
Used for small commercial or residential installations.
Protection of terminal devices, sensitive electronic equipment, telecom centers, automatic control centers, intelligent buildings, industrial enterprises, and medical institutes.
Installation:
Suitable as the final stage of protection in panels with Type 2 protection devices installed upstream.
These SPDs should be installed as close as possible to the equipment being protected.
Installed at a minimum conductor length of 10 meters (30 feet) from the electrical service panel to the point of utilization, for example cord connected, direct plug-in, receptacle type SPDs installed at the utilization equipment being protected. The distance (10 meters) is exclusive of the conductors provided with or used to attach SPDs.
