Mersen 83230118 STPT23-20K150V-3P Type 2+3 pluggable surge protection device with 20 kA maximum discharge current and 150 V AC maximum continuous operating voltage for 208 V AC three-phase TNC systems.
Original price was: £90.80.£67.10Current price is: £67.10.
The Mersen 83230118 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. Its modular construction allows rapid cartridge replacement, helping reduce maintenance time while maintaining reliable protection for electrical panels and sensitive equipment.
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 83230118 is suitable for protecting PLCs, drives, control panels, power supplies, instrumentation and automation equipment connected to 208 V AC systems.
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 83230118 is designed for panel-mounted surge protection in three-phase electrical installations. Its pluggable construction makes inspection and replacement straightforward, supporting efficient maintenance in industrial and commercial environments.
