Only One Name Means ProTek’Tion™ TWO LINE PAIR 4-20mA CONTROL LOOP PROTECTOR 420LB28 - 420LE60 420LB Description The 420LE/B series is a two stage transient voltage protector providing primary and secondary protection against lightning, inductive switching and electrostatic discharge (ESD) transient threats. The first stage diverts the transient current through the ground terminal return path and the second stage clamps the voltage to a safe level without interruption of service. The 420LE/B series is designed to protect data lines from differential (line to line) and mon mode (line to ground) transients. Terminals 1 and 2, 3 and 4 for the 420LE and pins 2 and 3, 4, and 5 for...
