Scope of application:
The second-level lightning protection box is mainly installed in
the floor power distribution, computer room power distribution and
other environments, as the second-level lightning protection of the
power distribution system, discharges the remaining surge, and
cooperates with the first-level lightning protection box to meet
the lightning protection acceptance Requirements and protection
needs.
The main parameters:
Maximum continuous working voltage Uc: 385VAC
Nominal discharge current In(8/20μs): 20kA or 40kA
Maximum discharge current Imax (8/20μs): 40kA or 80kA
Protection level Up: 1.8kV or 2.1kV
Protection mode: three-phase 4P, single-phase 2P
Product size: 350*260*130mm
Product Description:
Adopting Class II SPD to combine “3+1” circuit, protecting low
voltage equipment from surge damages, applied in TT system,
designed according to IEC61643-1/GB 18802.1
Main character:
1. Green light indicates normal and red light indicates fault for
operation
2. Built-in circuit breaker, and thermal disconnection device, when
the fault occurred, the thermal disconnection device will cut off
the SPD from the power net, the green window will change
3. Impulse counter function, recording the lightning events
4. External wiring terminal, easy for connection, suitable for
indoor application
