Why Choose the Mersen 83230135 Surge Protection Device?
The Mersen 83230135 is a compact and high-performance Type 2+3 surge protection device (SPD) designed to protect low-voltage electrical installations from transient overvoltages caused by lightning activity and electrical switching events. Part of the Mersen Surge-Trap® Pluggable STPT23 LF Series, it provides dependable surge protection for industrial, commercial and OEM electrical systems.
This 2-pole pluggable SPD is designed for 230 V AC single-phase TNS systems using a 2+0 configuration. It features leakage current free (LF) technology and integrated remote indication, making it suitable for installations where Power Line Communication compatibility and external status monitoring are important.
With a 20 kA maximum discharge current (Imax), 10 kA nominal discharge current (In) and a 275 V AC maximum continuous operating voltage (Uc), the Mersen 83230135 is ideal for protecting control panels, PLCs, power supplies, instrumentation, automation equipment and sensitive electrical loads.

Reliable Surge Protection with Remote Status Monitoring
Surge protection devices help prevent transient overvoltages from reaching sensitive electrical equipment by safely diverting surge energy away from connected loads. This helps reduce the risk of equipment damage, nuisance faults, data loss and unplanned downtime.
The Mersen 83230135 is designed for modern electrical installations where dependable surge protection, Power Line Communication compatibility and maintenance visibility are required. Its pluggable construction supports quick replacement, while the remote indication contact enables integration with alarm circuits, control systems or building management systems.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- Power Line Communication (PLC) installations.
- PLC and automation systems.
- Power supplies and instrumentation circuits.
- OEM machinery and panel building applications.
