Why Choose the Mersen 83230113 Surge Protection Device?

The Mersen 83230113 is a high-performance Type 2+3 surge protection device (SPD) designed to protect low-voltage electrical installations against transient overvoltages caused by lightning activity and electrical switching events. Part of the Mersen Surge-Trap® Pluggable STPT23 Series, it provides dependable surge protection for industrial, commercial and OEM electrical systems.

This compact 2-pole pluggable SPD is designed for 230/277 V AC single-phase TT systems using a 1+1 configuration. It provides coordinated protection between line-to-neutral (L-N) and neutral-to-earth (N-PE), while the integrated remote indication contact enables external monitoring of the device status.

With a 20 kA maximum discharge current (Imax), 10 kA nominal discharge current (In) and a 320 V AC maximum continuous operating voltage (Uc), the Mersen 83230113 is suitable for protecting control panels, PLCs, power supplies, instrumentation, switchboards and sensitive automation equipment.

Key Advantages

  • Compact Type 2+3 surge protection device for low-voltage installations.
  • 20 kA maximum discharge current for dependable transient overvoltage protection.
  • Remote indication contact for external SPD status monitoring.
  • 2-pole 1+1 TT configuration for line, neutral and earth protection.
  • Pluggable 2-module design supports fast replacement and maintenance.
  • Suitable for 230/277 V AC single-phase TT electrical systems.

Key Features

  • Mersen Surge-Trap® Pluggable STPT23 Series.
  • Type 2+3 / Class II + III surge protection device.
  • 20 kA maximum discharge current (Imax).
  • 10 kA nominal discharge current (In).
  • 320 V AC maximum continuous operating voltage.
  • 230/277 V AC nominal operating voltage.
  • Remote indication for maintenance monitoring.
  • DIN rail mounted pluggable construction.

Reliable Surge Protection with Remote Status Monitoring

Surge protection devices help prevent transient overvoltages from reaching sensitive electrical equipment by safely diverting surge energy away from connected loads. This helps reduce the risk of equipment damage, nuisance faults, data loss and unplanned downtime.

The Mersen 83230113 is designed for panel-mounted surge protection where remote status monitoring is required. Its pluggable construction allows straightforward cartridge replacement, while the remote indication contact supports integration with control circuits, alarm systems or building management systems.

Typical Applications

  • Industrial control panels.
  • Commercial electrical distribution boards.
  • Single-phase TT electrical systems.
  • PLC and automation equipment.
  • Power supplies and instrumentation circuits.
  • OEM machinery and panel building applications.
