Why Choose the Mersen 83230119 Surge Protection Device?
The Mersen 83230119 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 3-pole pluggable SPD is designed for 208 V AC three-phase TNC systems using a 3+0 configuration. It includes remote indication, allowing the SPD status to be monitored from external control circuits, alarm systems or building management equipment 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 83230119 is suitable for protecting PLCs, drives, control panels, power supplies, instrumentation and sensitive automation equipment connected to 208 V AC systems.

Reliable Surge Protection with Remote Status Monitoring
Surge protection devices help prevent damaging 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 83230119 is designed for panel-mounted surge protection in three-phase electrical installations where maintenance visibility is important. Its pluggable construction supports quick cartridge replacement, while the remote indication contact enables integration with control circuits or alarm systems.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- 208 V AC three-phase TNC electrical systems.
- PLC and automation equipment.
- Variable speed drives and motor control centres.
- OEM machinery and panel building applications.
