WTH-SG/TER

WTH-SG/TER DIN-rail surge protective devices for control signal are applied to the surge protection of 4-20mA control signal and twisted data pair which can prevent various dialing equipment from permanent damage or transient interruption arising from inductive over-voltage, over current and other transient surge voltage caused by surge and industrial noise etc.

Max. Discharge Current: 20kA (line GND/PE)

Voltage Protection Level (Up @line-line): 80V @3kV (1.2/50)

Voltage Protection Level (Up @line GND/PE): 350V @ 3kV (1.2/50)

Max Line Current: 800mA (per line)
