Why Choose the Mersen 83230103 Surge Protection Device?
The Mersen 83230103 is a compact and reliable Type 2+3 surge protection device (SPD) designed to protect low-voltage electrical systems from transient overvoltages. Part of the Mersen Surge-Trap® Pluggable STPT23 Series, it is suitable for industrial, commercial and OEM installations where sensitive electrical equipment requires dependable surge protection.
This pluggable SPD is designed for protection between line and neutral (L-N) in single-phase AC systems. Its modular format allows quick replacement of the protection cartridge, while the integrated remote indication feature enables status monitoring through control circuits, building systems or maintenance panels.
With a 20 kA maximum discharge current and 320 V AC maximum continuous operating voltage, the Mersen 83230103 helps protect control panels, automation equipment, PLCs, drives, power supplies and instrumentation from damaging voltage surges.
Key Advantages
- Compact Type 2+3 surge protection device for low-voltage installations.
- 20 kA Imax discharge capacity for reliable transient overvoltage protection.
- Remote indication for monitoring SPD status from control systems.
- Pluggable 1-module design simplifies maintenance and replacement.
- Designed for 230/277 V AC single-phase L-N applications.
- Suitable for industrial panels, commercial distribution boards and OEM machinery.
Key Features
- Mersen Surge-Trap® Pluggable STPT23 Series.
- Type 2+3 / Class II + III surge protection device.
- 20 kA maximum discharge current (Imax).
- 10 kA nominal discharge current (In).
- 320 V AC maximum continuous operating voltage.
- 1-pole L-N configuration.
- Remote indication contact for status signalling.
- DIN rail mounting for panel installation.
Surge Protection with Remote Status Monitoring
Surge protection devices help prevent damaging transient voltages from reaching sensitive equipment. By diverting surge energy away from connected loads, SPDs reduce the risk of premature equipment failure, unplanned downtime and costly repairs.
The Mersen 83230103 includes remote indication, making it particularly useful in control panels and installations where maintenance teams need to monitor protection status without opening the enclosure. This helps support planned maintenance and improves visibility of electrical protection systems.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- PLC and automation systems.
- Variable speed drives and motor control equipment.
- Power supplies and instrumentation circuits.
- OEM machinery and panel building applications.
