Why Choose the Mersen 83010104 Surge Protection Device?
The Mersen 83010104 is a high-performance Type 1 surge protection device (SPD) designed to protect low-voltage electrical installations against transient overvoltages caused by lightning strikes and switching surges. Part of the Mersen Surge-Trap Monobloc STMT1 Series, it provides robust first-stage surge protection for incoming power supplies in industrial, commercial and infrastructure applications.
Built in a compact monobloc DIN rail mounted format, the 83010104 is suitable for installation inside distribution boards, switchgear assemblies and control panels. Its 1-pole L-N configuration is designed for single-phase protection where dependable surge diversion is required at the electrical supply entry point.
With a 50 kA lightning impulse current rating, a 277 V nominal operating voltage and a 320 V maximum continuous operating voltage, the Mersen 83010104 is ideal for installations requiring strong protection against high-energy surge events.

Reliable Surge Protection for Electrical Installations
Surge protection devices such as the Mersen 83010104 help protect electrical systems by diverting transient overvoltages away from connected equipment. This helps reduce the risk of damage to control electronics, automation systems, power supplies and other sensitive electrical components.
As a Type 1 surge arrester, the 83010104 is particularly suited to installations exposed to direct or indirect lightning effects, including sites with external lightning protection systems, overhead supply lines or incoming distribution boards requiring first-stage surge protection.
Typical Applications
- Incoming power supply protection.
- Industrial control panels and switchboards.
- Commercial electrical distribution boards.
- Single-phase low-voltage installations.
- Buildings with lightning protection systems.
- Protection of sensitive electrical and electronic equipment.
