Mersen 83230117 STPT23-20K320V-2PM Type 2+3 pluggable surge protection device with remote indication, 20 kA maximum discharge current and 320 V AC maximum continuous operating voltage for 230/277 V AC TNS systems.
£68.85
The Mersen 83230117 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 delivers dependable protection for industrial, commercial and OEM electrical systems.
This 2-pole pluggable SPD is designed for 230/277 V AC single-phase TNS systems using a 2+0 configuration. It includes remote indication, enabling external monitoring of the surge protection status through control circuits, alarm systems or building management equipment.
With a 20 kA maximum discharge current (Imax), 10 kA nominal discharge current (In) and a 320 V AC maximum continuous operating voltage (Uc), the Mersen 83230117 provides effective protection for PLCs, variable speed drives, instrumentation, power supplies and sensitive automation equipment.
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 failure, nuisance faults, data loss and unplanned downtime.
The Mersen 83230117 is designed for panel-mounted surge protection where maintenance visibility is important. Its pluggable construction supports quick replacement, while the remote indication contact allows the SPD status to be monitored from external control or alarm circuits.
