The distinctive feature of this product is the output residual Low pressure and fast response time, especially when lightning surge passes through the protector, subsequent current will not appear. When the lightning protection box fails due to overheating, overcurrent, or breakdown due to lightning strikes, the built-in failure trip device can automatically disconnect it from the grid.
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
