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.
Key Advantages
Genuine ABB OVR Type 2+3 replacement cartridge.
20 kA maximum discharge current (Imax) with an 8/20 µs waveform.
5 kA nominal discharge current (In) for transient surge protection.
440 V AC maximum continuous operating voltage (Uc).
1.4 kV voltage protection level (Up).
Combined Type 2 and Type 3 protection characteristics for coordinated surge protection applications.
Pluggable cartridge construction supports quick replacement without changing the compatible SPD base.
Integrated visual status indication assists routine inspection and maintenance.
Key Features

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.
