Why Choose the Mersen 83230101 Surge Protection Device?
The Mersen 83230101 STPT23-20K150V-1PM 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 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 83230101 is designed for 120 V AC single-phase systems. The integrated remote indication feature allows SPD status to be monitored from external systems or control equipment.

Fine Surge Protection for Sensitive Equipment
Type 2+3 surge protection devices are used to limit transient overvoltages while providing a fine voltage protection level close to sensitive electrical equipment. They are commonly installed downstream of upstream Type 2 SPDs to improve protection coordination and reduce the risk of damage to connected devices.
The Mersen STPT23-20K150V-1PM combines compact dimensions with pluggable construction and remote indication, making it a practical choice for contractors, panel builders and maintenance engineers protecting single-phase electrical circuits and sensitive equipment.
Typical Applications
- Single-phase electrical distribution boards.
- Control panels and equipment enclosures.
- Building services and automation equipment.
- Power supplies and monitoring devices.
- Commercial electrical installations.
- Final stage surge protection close to sensitive loads.
