Features:
Consistent plug ability(even for N/PE spark gap)
It is compact devices designed to protect 3-phase+neutral networks at the main switchboard.
BR-40VG series Surge Protection are designed to protect against lighting surge voltages.
The protection circuitry is based on high energy varistor with thermal disconnection devices.
Maximum current of endure the lightning stroke 40KA.
There is an indicator on the cartridges to signal failure mode.
Thermal disconnect device for each individual connector
With or without floating remote indication contact
Time of response<25ns.
Din rail mountable (35 mm)
The color of the visible window shows operating status, green means normal, red means abnormal.
Conform to IEC61643-11 standards
AC Type 2 SPD is the secondary protection system for all low voltage electric installations.
This is installed in to each electrical switch boards and prevents the spread of surges in the electric systems, protecting the loads.
Application:
Suitable for system power protection, such as power distribution cabinet, switch cabinet, switch cabinet, AC distribution board, etc.
Protection of terminal devices.
BR-40VG AC SPD to protect from direct and indirect lightning impulse and other transient over voltage.
Used for protection against electrical transients.
