Mersen 83230001 SP23-20K150V Type 2+3 surge protection replacement cartridge with 20 kA maximum discharge current, 10 kA nominal discharge current and 150 V AC maximum continuous operating voltage for compatible Surge-Trap devices.
£19.43
The Mersen 83230001, also known as SP23-20K150V, is a compact Type 2+3 surge protection replacement cartridge designed for compatible Mersen Surge-Trap pluggable surge protection devices. It helps protect low-voltage electrical systems from transient overvoltages caused by switching operations, indirect lightning effects and network disturbances.
As part of the Mersen Surge-Trap STP T23 series, this replacement cartridge is intended for final-stage surge protection where sensitive equipment requires additional protection close to the point of use. Its plug-in format enables fast replacement during maintenance, helping restore protection without replacing the complete surge protection assembly.
With a 20 kA maximum discharge current, 10 kA nominal discharge current and 150 V AC maximum continuous operating voltage, the Mersen 83230001 is a practical choice for Type 2+3 surge protection applications on 120 V electrical systems.
Type 2+3 surge protection devices are commonly used as a final stage of protection close to sensitive electrical equipment. They help reduce residual transient overvoltages after upstream surge protection has handled larger surge currents, supporting improved protection for electronics, controls and building services systems.
The Mersen 83230001 replacement cartridge enables maintenance teams to restore surge protection quickly without replacing the complete SPD base. This makes it suitable for panel builders, electrical contractors and facilities engineers maintaining reliable low-voltage electrical systems.
