These are SPD (surge protective device) that comply with IEC standards for direct lightning surge 10/350μs, and induction lightning surge 8/20μs. These direct lightning protective products have the same kind of lightning protection performance that is required of protection level I (direct lightning surge 200kA), and are high performance devices that can be easily installed in areas that are prone to lightning strikes.We have a range of devices to protect against induction lightning, depending on the circuit configuration. We can also supply element type devices.
