Feature
1.Comply with GB18802-11/IEC61643-11, and UL1449 and other
international and domestic standards
2.Using Puth's high-performance PTMOV as the core lightning
protection component, it has excellent voltage protection level and
fail-safe performance. In the event of a power distribution system
failure (TOV), the protection module (PTMOV) can safely exit the
grid to avoid various failures caused by Faults, such as grid
failures or even electrical fires, etc.
3.Full mode protection (L-N, L-PE, N-PE, L-L), to provide
protection for all possible lines through which the surge current
passes, common mode overvoltage and differential mode overvoltage
can be effectively suppressed, and protection level distortion is
avoided.
4.Optimize parallel redundancy technology to realize module current
sharing. The current flowing through each module (PTMOV) decreases
as the number of parallel connections increases, so the product has
a longer life expectancy and is more effective in resisting
short-term multiple lightning strikes or high-intensity lightning
currents . When a module is damaged or aging due to lightning
strikes, the module automatically exits the protection sequence
without affecting the overall protection function of the product,
so the protector does not require frequent maintenance during the
life cycle *.
5.Optional sine wave tracking function can effectively attenuate
high-frequency interference or spikes in AC power supply and
improve protection performance (PSP B, C series).
6.The rated short-circuit current is up to 200kArms (UL1449 Fourth
Edition SCCR test), and the PSP series can be applied to any
protection position of the power distribution system.
7.Optimized internal structure design, and due to the excellent
characteristics of PTMOV, the product is compact and saves
installation space
8.With failure LED display, and alarm function.
9.Built-in lightning event monitoring device to accurately record
the frequency of lightning or surge events.
10.IP65 (or NEMA4, 4X) waterproof housing, suitable for indoor and
outdoor installation.
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
