Why Choose the Mersen 83010102 Surge Protection Device?

The Mersen 83010102 is a high-performance Type 1 surge protection device (SPD) designed for neutral-to-earth protection in low-voltage AC electrical installations. Part of the Mersen Surge-Trap Monobloc STMT1 Series, it provides robust first-stage surge protection against high-energy transient overvoltages caused by lightning activity and switching surges.

Built in a compact monobloc DIN rail mounted format, the 83010102 is suitable for installation inside distribution boards, switchgear assemblies and control panels. Its N-PE protection mode makes it ideal for TT and TN-S systems where neutral-to-earth surge protection is required as part of a coordinated SPD arrangement.

With a 100 kA lightning impulse current rating, 255 V maximum continuous operating voltage and 1-pole neutral configuration, the Mersen 83010102 provides dependable protection for sensitive electrical and electronic equipment in demanding industrial and commercial environments.

Key Advantages

  • High-performance Type 1 / Class I surge protection device.
  • 100 kA Iimp lightning impulse discharge capacity.
  • N-PE protection mode for neutral-to-earth surge protection.
  • 255 V maximum continuous operating voltage.
  • Compact 2-module monobloc DIN rail design.
  • Suitable for TT and TN-S electrical systems.

Key Features

  • Mersen Surge-Trap Monobloc STMT1 Series.
  • Type 1 / Class I SPD.
  • 100 kA Iimp (10/350 μs).
  • Neutral-to-earth N-PE protection.
  • 1-pole monobloc construction.
  • 255 V maximum continuous operating voltage.
  • Fast response time for transient overvoltage protection.
  • DIN rail mounted design for distribution boards and panels.

Reliable Neutral-to-Earth Surge Protection

Surge protection devices such as the Mersen 83010102 help protect electrical systems by diverting transient overvoltages safely away from connected equipment. This helps reduce the risk of damage to power supplies, automation systems, control electronics and other sensitive electrical components.

As a Type 1 neutral SPD, the 83010102 is particularly suited to installations exposed to lightning effects, overhead supply lines or incoming distribution boards requiring coordinated N-PE surge protection within TT or TN-S electrical networks.

Typical Applications

  • Neutral-to-earth surge protection.
  • Main incoming distribution boards.
  • Industrial control panels and switchboards.
  • Commercial low-voltage electrical installations.
  • TT and TN-S electrical systems.
  • Buildings with external lightning protection systems.
