Mersen 83230134 STPT23-20K275V-2P-LF Type 2+3 leakage current free surge protection device with 20 kA maximum discharge current for 230 V AC TNS electrical systems.
£65.29
The Mersen 83230134 is a high-performance Type 2+3 surge protection device (SPD) designed to protect low-voltage electrical installations from transient overvoltages caused by lightning strikes and switching events. Part of the Mersen Surge-Trap® Pluggable STPT23 LF Series, it provides dependable surge protection for industrial, commercial and OEM electrical systems while offering leakage current free (LF) operation for Power Line Communication (PLC) applications.
This compact 2-pole pluggable SPD is designed for 230 V AC single-phase TNS systems using a 2+0 configuration. The leakage current free design helps prevent interference with PLC communication systems while delivering excellent protection for connected electrical equipment.
With a 20 kA maximum discharge current (Imax), 10 kA nominal discharge current (In) and a 275 V AC maximum continuous operating voltage (Uc), the Mersen 83230134 is ideal for protecting PLCs, variable speed drives, control panels, instrumentation, power supplies and other sensitive industrial automation equipment.
Surge protection devices safely divert transient overvoltages away from connected electrical equipment, helping reduce downtime, improve system reliability and extend the operating life of automation and power distribution equipment.
The Mersen Surge-Trap® STPT23 LF Series has been developed for installations where reliable surge protection and Power Line Communication compatibility are both essential. Its leakage current free technology and pluggable construction make it well suited to modern industrial control panels and electrical distribution systems.
