The Signal Line Surge Protector is designed to protect signal lines from surges. It comes in a pair and has a maximum continuous operating voltage of 38VDC and 30VAC. The maximum discharge current is 4.8 kA per line at 8/20ms (9.6 kA in common mode). The protector can handle a maximum load current of 6A. It has a voltage protection level of <75V at 1kV/µs (L-L, L-PE). The protector is designed for series connection and has a replacement top module with an EC90 base that provides 90V isolation between the DIN rail earth and shield. It is suitable for applications with load currents up to 6A.
