Why Choose the Mersen 83020105 Surge Protection Device?
The Mersen 83020105 is a robust Type 2 surge protection device (SPD) designed to protect low voltage electrical installations against transient overvoltages caused by switching operations and indirect lightning events. As part of the Mersen Surge-Trap® Pluggable STPT2 Series, it delivers dependable protection for commercial, industrial and automation applications while offering convenient maintenance through its pluggable construction.
Designed for single phase 120 V AC L-N systems, the STPT2-40K150V-1PM provides a 40 kA maximum discharge current (Imax), 20 kA nominal discharge current (In) and includes a remote indication contact for integration into monitoring systems. The replaceable cartridge allows fast servicing with minimal disruption to electrical installations.
With a 150 V AC maximum continuous operating voltage (Uc), compact DIN rail mounting and compliance with EN/IEC 61643-11 and UL 1449, the Mersen 83020105 is an excellent choice for protecting sensitive electrical equipment, control panels and distribution boards.
