Mersen 83010102 Surge-Trap Monobloc STMT1 Type 1 surge protection device, catalogue number STMT1-100K-N, rated at 100 kA Iimp with 255 V maximum continuous operating voltage and N-PE neutral-to-earth protection.
£240.36
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.
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.
