Why Choose the ABB OVR T2-T3 20-440 C QS Replacement Cartridge?
The ABB OVR T2-T3 20-440 C QS, order code 2CTB803876R0600, is a replacement surge protection cartridge for compatible ABB OVR Type 2+3 surge protective devices. Part of the ABB OVR QuickSafe range and ABB's Surge Protection Devices product group, it provides a replaceable protection element for low-voltage AC installations where combined Type 2 and Type 3 protection is required.
The OVR T2-T3 20-440 C QS provides a maximum discharge current (Imax) of 20 kA and a nominal discharge current (In) of 5 kA using an 8/20 µs waveform. It is rated for a maximum continuous operating voltage (Uc) of 440 V AC and has a voltage protection level (Up) of 1.4 kV, providing effective limitation of transient overvoltages in compatible OVR T2-T3 assemblies.
Designed as a compact, pluggable replacement cartridge, the OVR T2-T3 20-440 C QS allows a worn protection module to be exchanged while retaining the compatible installed SPD base. Integrated status indication simplifies inspection, while its Type 2+3 characteristics make the cartridge suitable for protection against indirect lightning effects and lower-energy transients close to sensitive terminal equipment.

Combined Type 2 and Type 3 Replacement Surge Protection
Combined Type 2+3 surge protective devices are used to limit transient overvoltages caused by indirect lightning effects and switching events while also providing a low residual voltage suitable for protection closer to sensitive terminal equipment. This makes Type 2+3 protection useful in coordinated surge protection systems installed in intermediate distribution boards and near vulnerable electrical or electronic loads.
The OVR T2-T3 20-440 C QS provides the replaceable phase protection element for compatible ABB OVR T2-T3 assemblies. Its 440 V AC maximum continuous operating voltage, 20 kA maximum discharge current and compact pluggable construction support reliable maintenance of commercial and industrial surge protection installations.
