Reliable Surge Protection for Electrical Distribution Systems
Surge protection devices help protect electrical installations from transient overvoltages caused by lightning activity, switching operations and network disturbances. Type 1+2 SPDs are commonly installed at the origin of an electrical installation, particularly where external lightning protection or high exposure to surge events is present.
The Mersen 83120005 replacement cartridge allows maintenance teams to restore surge protection functionality without replacing the complete SPD assembly. This makes it a practical solution for panel builders, electrical contractors and facilities teams responsible for keeping critical power distribution systems protected.
Typical Applications
- Incoming electrical distribution panels.
- Neutral line surge protection in TT and TN systems.
- Industrial switchboards and control panels.
- Commercial building electrical distribution systems.
- Installations with external lightning protection systems.
- Maintenance replacement for compatible Mersen Surge-Trap devices.
