Why Choose the Mersen 83230109 Surge Protection Device?

The Mersen 83230109 is a compact and reliable Type 2+3 surge protection device (SPD) designed to protect low-voltage electrical installations from transient overvoltages caused by lightning activity and electrical switching events. Part of the Mersen Surge-Trap® Pluggable STPT23 Series, it provides fine surge protection for industrial, commercial and OEM electrical systems.

This pluggable SPD is designed for 120/208 V AC TT systems and features a 2-pole 1+1 configuration with protection between line, neutral and earth. The integrated remote indication contact enables external status monitoring, helping maintenance teams identify when replacement or inspection is required.

With a 20 kA maximum discharge current (Imax), 10 kA nominal discharge current (In) and 150 V AC maximum continuous operating voltage (Uc), the Mersen 83230109 is ideal for protecting PLCs, control panels, power supplies, instrumentation and sensitive automation equipment.

Surge Protection with Remote Status Monitoring

Surge protection devices help prevent damaging voltage spikes from reaching sensitive electrical equipment by safely diverting transient energy away from connected loads. This reduces the risk of premature equipment failure, nuisance faults and unplanned downtime.

The Mersen 83230109 is particularly useful where surge protection status needs to be monitored remotely from a control circuit, alarm system or building management system. Its pluggable format also supports efficient maintenance, making it well suited to panel builders and industrial electrical installations.

Typical Applications

  • Industrial control panels.
  • Commercial electrical distribution boards.
  • PLC and automation systems.
  • Power supplies and instrumentation circuits.
  • Communication and monitoring equipment.
  • OEM machinery and panel building applications.
