Why Choose the Mersen 83230000 Type 2+3 Replacement Cartridge?
The Mersen 83230000, also known as SP23-20K-N, is a compact Type 2+3 surge protection replacement cartridge designed for compatible Mersen Surge-Trap pluggable surge protection devices. It helps protect sensitive electrical equipment from transient overvoltages caused by switching operations, indirect lightning effects and network disturbances.
As part of the Mersen Surge-Trap STP T23 series, this neutral cartridge is intended for fine surge protection where Type 2 protection is already installed upstream. Its plug-in format enables fast replacement during maintenance, helping restore protection quickly without replacing the complete surge protection assembly.
With a 20 kA maximum discharge current, 255 V AC maximum continuous operating voltage and N-PE neutral protection configuration, the Mersen 83230000 is a practical choice for final-stage surge protection in distribution boards, control panels and sensitive equipment circuits.

Fine Surge Protection for Sensitive Equipment
Type 2+3 surge protection devices are commonly used as a final stage of protection close to sensitive equipment. They help reduce residual transient overvoltages after upstream surge protection has discharged larger surge currents, supporting improved protection for control systems, electronics and building services equipment.
The Mersen 83230000 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 responsible for maintaining reliable low-voltage electrical systems.
Typical Applications
- Final-stage surge protection circuits.
- Electrical distribution boards.
- Industrial control panels and automation cabinets.
- Commercial building services panels.
- Protection of sensitive electronic equipment.
- Maintenance replacement for compatible Mersen Surge-Trap devices.
