The Mersen 83020107 is a premium Type 2 surge protection device (SPD) engineered to protect low voltage electrical installations from transient overvoltages caused by switching operations and indirect lightning strikes. Part of the trusted Mersen Surge-Trap® Pluggable STPT2 Series, this device provides reliable surge protection for industrial, commercial and automation applications.
Designed for 230 V AC single phase L-N systems, the STPT2-40K275V-1PM offers a 40 kA maximum discharge current (Imax), a 20 kA nominal discharge current (In) and incorporates an integrated remote indication contact for easy status monitoring. Its pluggable cartridge enables rapid replacement, helping minimise maintenance time and system downtime.
With a 275 V AC maximum continuous operating voltage (Uc), compact DIN rail mounting and compliance with EN/IEC 61643-11 and UL 1449, the Mersen 83020107 delivers dependable protection for electrical distribution boards, control panels and sensitive electronic equipment.
Type 2 surge protection devices help protect electrical installations by diverting damaging transient overvoltages away from connected equipment. This reduces the risk of equipment failure, extends the service life of electrical components and improves the reliability of power distribution systems.
The Mersen Surge-Trap® STPT2 Series combines high surge handling capability with a replaceable pluggable cartridge and integrated remote indication, making it an ideal solution for modern industrial and commercial electrical installations.
