£34.58
The Mersen 83230106 is a compact and reliable Type 2+3 surge protection device (SPD) designed to protect low-voltage electrical installations from transient overvoltages. Part of the Mersen Surge-Trap® Pluggable STPT23 Series, it provides dependable protection for neutral surge paths in industrial, commercial and OEM electrical systems.
This pluggable SPD is designed for neutral protection and is suitable for use in surge protection assemblies where a dedicated N-PE protection module is required. Its modular 1-pole design allows quick replacement, helping reduce maintenance time and improve the long-term reliability of electrical protection systems.
With a 20 kA maximum discharge current (Imax), 10 kA nominal discharge current (In) and 255 V AC maximum continuous operating voltage (Uc), the Mersen 83230106 is suitable for protecting low-voltage installations where neutral-to-earth surge protection is required.
Neutral surge protection devices help divert transient overvoltages safely away from sensitive equipment and electrical installations. They are commonly used as part of coordinated SPD assemblies to provide complete protection across line, neutral and earth conductors.
The Mersen 83230106 is designed for panel-mounted installations where dependable neutral protection is required. Its pluggable construction makes inspection and replacement straightforward, supporting planned maintenance and reducing system downtime.
