Mersen 83230116 STPT23-20K320V-2P Type 2+3 pluggable surge protection device with 20 kA maximum discharge current and 320 V AC maximum continuous operating voltage for 230/277 V AC TNS systems.
£59.34
The Mersen 83230116 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 surge 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. Its modular construction allows rapid cartridge replacement, helping reduce maintenance time while maintaining reliable protection for control panels and electrical distribution equipment.
Featuring 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 83230116 provides effective protection for PLCs, variable speed drives, instrumentation, power supplies and sensitive industrial automation equipment.
Surge protection devices safely divert transient overvoltages away from connected electrical equipment, helping minimise equipment damage, reduce downtime and improve the long-term reliability of industrial power systems.
The Mersen Surge-Trap® STPT23 Series has been developed for installation close to sensitive equipment, providing dependable protection for industrial automation, motor control and commercial electrical distribution systems.
