Features:
These are suitable for second level of protection in supply distribution panels.
BR-40VG OEM Customized 1P+NPE Imax 40kA AC Power Supply SPD is designed according to IEC61643 standard.
BR-40VG series Surge Protection are designed to protect against lighting surge voltages.
End of Life Indicator (Red & Green).
There is an indicator on the cartridges to signal failure mode.
With good sealing, it is designed as module and 35mm DIN-Rail Mounting.
With or without floating remote indication contact
Temperature control circuit breaker and built-in over-current protective circuit, the modular SPD can release automatically to avoid fire danger when it breaks down.
Protection in small module width.
Faulty cartridges can be replaced without changing the entire SPD.
This industrial surge protector for AC helps prevent damage from VAC overvoltage that can be caused by lightning surge and other strong electrical power spikes.
Cartridges can be replaced with mains voltage ON.
This is installed in to each electrical switch boards and prevents the spread of surges in the electric systems, protecting the loads.
Application:
It can be installed in the low voltage power distribution cabinet/box of buildings, to protect all kinds of power equipment in the single phase power distribution system between LPZ1 and LPZ2.
Protection of terminal devices.
For example, low voltage general electricity Cabinet and/or distribution board of buildings, outdoor electricity cabinet/distribution box, any circumstance need to record the lightning leakage, power supply system: TT, TN.
Used for protection against electrical transients.
