Why Choose the Mersen 83230100 Surge Protection Device?
The Mersen 83230100 STPT23-20K150V-1P is a compact Type 2+3 surge protection device (SPD) designed to protect low-voltage electrical installations from transient overvoltages caused by switching operations and indirect lightning activity. As part of the Mersen Surge-Trap® Pluggable STPT23 Series - 20kA, it provides fine voltage protection for sensitive electrical and electronic equipment.
This pluggable surge protection device is suitable for use as a final stage of protection, particularly where Type 2 surge protection is installed upstream. Its single-pole, one-module construction makes it easy to install in compact distribution boards, control panels and equipment protection enclosures.
With a 20 kA maximum discharge current, 150 V AC maximum continuous operating voltage and L-N protection mode, the Mersen 83230100 is designed for 120 V AC single-phase systems. Its DIN rail mounting format allows straightforward installation in electrical panels close to the equipment being protected.
