Why Choose the Mersen 83020004 Type 2 Replacement Cartridge?
The Mersen 83020004, also known as SP2-40K440V, is a reliable Type 2 surge protection replacement cartridge designed for compatible Mersen Surge-Trap pluggable surge protection devices. It helps protect electrical installations against transient overvoltages caused by switching operations, indirect lightning effects and power network disturbances.
As part of the Mersen Surge-Trap STP T2 40 series, this replacement cartridge is suitable for low-voltage distribution systems where coordinated surge protection is required. Its plug-in design allows fast replacement during maintenance, helping reduce downtime while restoring protection to the surge protection assembly.
With a 40 kA maximum discharge current, 20 kA nominal discharge current and 440 V AC maximum continuous operating voltage, the Mersen 83020004 is a practical choice for Type 2 SPD applications on 400 V electrical systems.

Reliable Type 2 Surge Protection for Distribution Systems
Type 2 surge protection devices are commonly installed in distribution boards and sub-distribution panels to limit transient overvoltages before they reach connected electrical equipment. They are often used as the second stage of protection where Type 1 devices are installed upstream, or as the first stage in installations without direct lightning exposure.
The Mersen 83020004 replacement cartridge enables maintenance teams to restore surge protection quickly without replacing the complete SPD base. This makes it suitable for panel builders, electrical contractors and facilities engineers maintaining commercial and industrial electrical systems.
Typical Applications
- 400 V low-voltage electrical systems.
- Electrical distribution boards.
- Commercial building services panels.
- Industrial control panels and switchboards.
- Sub-distribution surge protection systems.
- Maintenance replacement for compatible Mersen Surge-Trap devices.
