Why Choose the Mersen 83230130 Surge Protection Device?
The Mersen 83230130 is a high performance Type 2+3 Surge Protection Device (SPD) designed to protect low voltage electrical installations against transient overvoltages. Part of the Mersen Surge-Trap® Pluggable STPT23 LF Series, this device provides reliable protection for three-phase plus neutral electrical systems used in commercial, industrial and automation environments.
Designed for installation as the final stage of surge protection, the device helps safeguard sensitive electrical equipment from voltage spikes caused by lightning strikes and switching operations. Its pluggable modular design enables rapid cartridge replacement while reducing maintenance time and ensuring continued protection.
With a maximum discharge current of 20 kA (8/20 μs), a 275 V AC continuous operating voltage (Uc) and a 3+1 TT configuration, the Mersen 83230130 is ideal for protecting switchboards, control panels, PLCs, drives and industrial automation equipment operating on 230/400 V AC systems.

Reliable Protection Against Electrical Surges
Surge protection devices safely divert transient overvoltages away from connected equipment before they can cause insulation failure, electronic damage or costly downtime. Installing an SPD helps improve equipment reliability while extending the operational life of sensitive electrical systems.
The Mersen Surge-Trap® STPT23 LF Series is designed as the final stage of protection in low voltage installations where upstream Type 2 protection is already installed, making it suitable for industrial automation, commercial buildings, switchboards and machinery applications.
Typical Applications
- Industrial control panels.
- Electrical distribution boards.
- Automation and machinery systems.
- Commercial buildings.
- PLC, drive and instrumentation protection.
- Three-phase plus neutral TT electrical installations.
