B series distribution surge protective devices are mainly appicable to power distribution system for class B/ C or type 1/2 protection, to protect electrical equipment from the impact of lightning electromagnetic pulse, induced over voltage, transist operation and resonance( less than 100 μs) over voltage.
Adopt special impact fuse, with high reliability
Comes with remote alarm dry contacts for remote monitoring; equipped with lightning strikes counter to accurately record the number of lightning strikes, (option)
With module alarm indicator light to provide module degradation indication, with power status indicator light to indicate the working status of the lightning surge protector
Built-in thermal protection, stable and reliable operation
For indoor use, outdoor models are also available, with waterproof, dustproof and anti-corrosion chassis
Can be customized according to your request (pls check the attached photo)
