Mersen 83230110 STPT23-20K275V-2PG-LF Type 2+3 leakage current free surge protection device with 20 kA maximum discharge current for 230 V AC TT electrical systems.
Original price was: £68.82.£50.86Current price is: £50.86.
The Mersen 83230110 is a high-performance Type 2+3 surge protection device (SPD) developed to protect low-voltage electrical installations from transient overvoltages caused by lightning strikes and switching events. As part of the Mersen Surge-Trap® Pluggable STPT23 LF Series, it provides dependable protection for industrial, commercial and OEM electrical systems while remaining Power Line Communication (PLC) friendly.
This compact 2-pole pluggable SPD is designed for 230 V AC TT (1Ph+N) systems using a 1+1 configuration, providing coordinated protection between line-to-neutral (L-N) and neutral-to-earth (N-PE). Its leakage current free design makes it particularly suitable for installations using power line communication technologies.
With a 20 kA maximum discharge current (Imax), 10 kA nominal discharge current (In) and a 275 V AC maximum continuous operating voltage (Uc), the Mersen 83230110 provides reliable protection for control panels, PLCs, power supplies, instrumentation and sensitive industrial automation equipment.
Surge protection devices safely divert transient overvoltages away from connected equipment, helping to reduce downtime, improve system reliability and extend the service life of sensitive electrical devices.
The Mersen Surge-Trap® STPT23 LF Series is engineered for applications requiring dependable surge protection while maintaining compatibility with power line communication systems. Its compact pluggable construction simplifies maintenance and replacement within electrical distribution panels.
