The Phoenix Contact PT 2-PE/S-230AC-ST is a Type 3 surge protection plug engineered for device-level protection on 1-phase power supply networks. It safeguards sensitive electronic equipment from transient overvoltage events by diverting surge currents and clamping voltage peaks across L-N, L-PE, and N-PE pathways. The two-piece design comprises a base element compatible with NS 35/7.5 and NS 35/15 DIN rails and a tool-free replaceable plug module. An integrated LED provides optical indication of disconnection status, supported by a remote indication contact for monitoring integration.
