Why Choose the Mersen 83230134 Surge Protection Device?

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.
