Why Choose the Mersen 83230115 Surge Protection Device?
The Mersen 83230115 is a compact and reliable 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 Series, it provides dependable fine surge protection for industrial, commercial and OEM electrical systems.
This 2-pole pluggable SPD is designed for 120 V AC single-phase TNS systems using a 2+0 configuration. It includes remote indication, allowing the SPD status to be monitored from control circuits, alarm systems or building management systems without opening the enclosure.
With a 20 kA maximum discharge current (Imax), 10 kA nominal discharge current (In) and a 150 V AC maximum continuous operating voltage (Uc), the Mersen 83230115 is suitable for protecting control panels, PLCs, power supplies, instrumentation and sensitive electrical equipment connected to 120 V AC systems.

Reliable Surge Protection with Remote Status Monitoring
Surge protection devices help stop damaging transient overvoltages from reaching sensitive electrical equipment by safely diverting surge energy away from connected loads. This helps reduce the risk of equipment failure, nuisance faults, data loss and unplanned downtime.
The Mersen 83230115 is designed for panel-mounted surge protection in 120 V TNS electrical installations. Its pluggable construction supports quick replacement, while the remote indication contact provides useful visibility for preventative maintenance and system monitoring.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- 120 V AC TNS electrical systems.
- PLC and automation equipment.
- Power supplies and instrumentation circuits.
- OEM machinery and panel building applications.
