Reliable Surge Protection for Electrical Installations
Surge protection devices such as the Mersen 83010103 help protect electrical systems by diverting transient overvoltages away from connected equipment. This reduces the risk of damage to power supplies, control electronics, automation systems and other sensitive electrical components.
As a Type 1 surge arrester, the 83010103 is particularly suited to installations where the electrical supply may be exposed to direct or indirect lightning effects, including sites with external lightning protection systems or overhead supply lines.
Typical Applications
- Incoming power supply protection.
- Industrial control panels and switchboards.
- Commercial electrical distribution boards.
- Single-phase low-voltage installations.
- Lightning protection system coordination.
- Protection of sensitive electrical and electronic equipment.
