Fine Surge Protection for Sensitive Electrical 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 83230002 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 and 277 V low-voltage electrical systems.
- Final-stage surge protection circuits.
- Electrical distribution boards.
- Industrial control panels and automation cabinets.
- Commercial building services panels.
- Maintenance replacement for compatible Mersen Surge-Trap devices.
