Why Choose the Mersen 44020005 K2-440 Replacement Cartridge?
The Mersen 44020005, also known as the K2-440, is a genuine Type 2 surge protection replacement cartridge for compatible Mersen Surge-Trap® K2 Series surge protection devices. Designed for straightforward maintenance, this pluggable module restores surge protection without requiring replacement of the complete SPD assembly, reducing both downtime and maintenance costs.
The K2-440 is intended for applications requiring a 440 V AC maximum continuous operating voltage (Uc). It provides dependable protection against transient overvoltages caused by lightning activity and electrical switching events, making it suitable for industrial power distribution systems operating at higher voltages.
Its modular plug-in design allows rapid replacement when the cartridge reaches the end of its service life, while the integrated visual status indicator enables quick inspection during routine maintenance.
