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 65VDC and 50VAC. The maximum discharge current is 4.8 kA per line at 8/20ms (9.6 kA common mode). The maximum load current is 6A. The voltage protection level is less than 130V at 1kV/µs (L-L, L-PE). It features a series connection and 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.
