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 *.
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
