The Mersen 83020000, also known as SP2-40K-N, is a dependable Type 2 surge protection replacement cartridge designed for compatible Mersen Surge-Trap pluggable surge protection devices. It is used to help protect electrical installations against transient overvoltages caused by switching operations, network disturbances and indirect lightning effects.
As part of the Mersen Surge-Trap STP T2 40 series, this neutral replacement cartridge is suitable for coordinated surge protection systems in commercial, industrial and building services applications. Its pluggable cartridge format allows quick replacement during maintenance, helping restore protection without replacing the full surge protection assembly.
With a 40 kA discharge rating, 265 V AC maximum continuous operating voltage and N-PE protection configuration, the Mersen 83020000 is a practical choice for maintaining Type 2 surge protection in electrical distribution panels and switchboards.
Type 2 surge protection devices are commonly installed in distribution boards and sub-distribution panels to limit transient overvoltages before they reach sensitive downstream equipment. They are typically used as the second stage of protection where Type 1 devices are installed upstream, or as the first stage in installations without direct lightning exposure.
The Mersen 83020000 replacement cartridge helps maintenance teams restore surge protection quickly and efficiently. Its plug-in design makes it suitable for panel builders, electrical contractors and facilities engineers maintaining power distribution systems in commercial and industrial environments.
