Why Choose the Mersen 83010107 Surge Protection Device?
The Mersen 83010107 is a robust Type 1 surge protection device (SPD) engineered to safeguard low-voltage electrical installations against transient overvoltages caused by direct lightning strikes and switching surges. As part of the Mersen Surge-Trap® Monobloc STMT1 Series, it provides dependable first-stage surge protection for industrial, commercial and infrastructure power systems.
Featuring a compact monobloc DIN rail mounted design, the 83010107 is suitable for installation within incoming distribution boards, switchgear and control panels. Its single-pole L-N configuration offers effective protection for 400 V AC systems exposed to high-energy lightning events.
With a 50 kA lightning impulse current rating, a 400 V nominal operating voltage and a 440 V maximum continuous operating voltage (Uc), the Mersen 83010107 provides reliable protection for sensitive electrical equipment in demanding industrial environments.

Reliable Surge Protection for Critical Electrical Systems
The Mersen 83010107 safely diverts high-energy transient overvoltages to earth before they can damage sensitive electrical and electronic equipment. Installing a Type 1 SPD at the incoming supply improves system reliability while reducing downtime caused by lightning-induced surges.
It is particularly suited to installations with external lightning protection systems, overhead supply lines or locations exposed to frequent lightning activity, providing the first level of surge protection in accordance with EN IEC 61643-11.
Typical Applications
- Industrial control panels.
- Main incoming distribution boards.
- Commercial electrical installations.
- Manufacturing facilities.
- Water treatment plants.
- Buildings with external lightning protection systems.
