Why Choose the Mersen 83020117 Surge Protection Device?
The Mersen 83020117 is a premium Type 2 surge protection device (SPD) engineered to protect low voltage electrical installations against transient overvoltages caused by switching operations, utility disturbances and indirect lightning strikes. As part of the proven Mersen Surge-Trap® Pluggable STPT2 Series, it provides dependable surge protection for commercial, industrial and automation applications.
The STPT2-40K275V-2PGM is designed for 230 V AC 1Ph+N TT systems and delivers a 40 kA maximum discharge current (Imax) together with a 20 kA nominal discharge current (In). Its 1+1 TT configuration provides protection between line and neutral as well as neutral and protective earth, while the integrated remote indication contact enables continuous monitoring of the device status.
With a 275 V AC maximum continuous operating voltage (Uc), compact 2 pole, 2 module pluggable construction and DIN rail mounting, the Mersen 83020117 is ideal for protecting switchboards, distribution boards, control panels and sensitive electrical equipment in demanding low voltage installations.
