Why Choose the Mersen 83230003 Type 2+3 Replacement Cartridge?
The Mersen 83230003, also known as SP23-20K275V-LF, is a compact Type 2+3 surge protection replacement cartridge designed for compatible Mersen Surge-Trap pluggable surge protection devices. It helps protect low-voltage electrical systems from transient overvoltages caused by switching operations, indirect lightning effects and network disturbances.
As part of the Mersen Surge-Trap STPT23 LF series, this replacement cartridge is suitable for final-stage surge protection close to sensitive equipment and is compatible with PLC network applications. Its plug-in format enables fast replacement during maintenance, helping restore protection without replacing the complete surge protection assembly.
With a 20 kA maximum discharge current, 275 V AC maximum continuous operating voltage and 1 pole configuration, the Mersen 83230003 is a practical choice for Type 2+3 surge protection applications on 230 V electrical systems.

Fine Surge Protection for Sensitive Equipment
Type 2+3 surge protection devices are commonly used as a final stage of protection close to sensitive electrical equipment. They help reduce residual transient overvoltages after upstream surge protection has handled larger surge currents, supporting improved protection for electronics, controls and building services systems.
The Mersen 83230003 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 reliable low-voltage electrical systems.
Typical Applications
- 230 V low-voltage electrical systems.
- Final-stage surge protection circuits.
- PLC and control network protection applications.
- Electrical distribution boards.
- Industrial control panels and automation cabinets.
- Maintenance replacement for compatible Mersen Surge-Trap devices.
