Why Choose the ABB OVR T2-T3 20-275 C QS Replacement Surge Protection Cartridge?
The ABB OVR T2-T3 20-275 C QS is a replacement phase cartridge for compatible ABB OVR QuickSafe combined Type 2 and Type 3 surge protective devices. Designed for the ABB OVR T2-T3 20-275 range, it enables a worn or end-of-life surge protection cartridge to be replaced without changing the complete SPD base.
The cartridge provides a maximum discharge current (Imax) of 20 kA and a nominal discharge current (In) of 5 kA using an 8/20 µs surge-current waveform. It is designed for 230 V AC nominal applications with a 275 V AC maximum continuous operating voltage (Uc) and provides a 0.9 kV voltage protection level (Up).
As a genuine ABB QuickSafe pluggable replacement cartridge, the OVR T2-T3 20-275 C QS provides a straightforward way to restore surge protection after a cartridge reaches end of life. Its integrated status indicator assists with visual condition checking, while the compact single-pole cartridge format is designed for direct installation into compatible ABB OVR T2-T3 pluggable bases.

Reliable Replacement Protection for ABB OVR T2-T3 QuickSafe SPDs
Pluggable surge protective devices allow the protection element to be replaced independently of the permanently wired base. When a surge cartridge reaches the end of its service life, replacing only the cartridge can restore the SPD to its intended protection capability while reducing maintenance time and avoiding unnecessary rewiring of the installation.
The ABB OVR T2-T3 20-275 C QS provides the electrical characteristics required for compatible 275 V OVR T2-T3 QuickSafe devices, including a 20 kA maximum discharge current, 5 kA nominal discharge current and 0.9 kV voltage protection level. Its plug-in construction and visual status indication make it a practical spare component for maintaining ABB surge protection installations.
