Why Choose the ABB OVR T1-T2 12.5-275s C QS Replacement Cartridge?
The ABB OVR T1-T2 12.5-275s C QS is a high-performance replacement surge protection cartridge for compatible ABB OVR QuickSafe combined Type 1 + Type 2 surge protective devices. Identified by ABB order code 2CTB815710R2600, this single-pole cartridge is designed to restore lightning-current and transient-overvoltage protection without replacing the complete installed SPD assembly.
As part of the ABB OVR QuickSafe range, the cartridge provides combined Type 1 and Type 2 protection, with a 12.5 kA impulse current rating using a 10/350 µs waveform, a 20 kA nominal discharge current and an 80 kA maximum discharge current. Its mechanical status indication enables straightforward inspection of the protection element during routine electrical maintenance.
With a 230/400 V AC nominal system voltage, 275 V AC maximum continuous operating voltage and 1.4 kV voltage protection level, the OVR T1-T2 12.5-275s C QS is suitable for compatible ABB surge protection assemblies used on TN-C, TN-S and TT low-voltage distribution systems. The plug-in design enables rapid cartridge replacement while retaining the installed DIN-rail base and associated wiring.

Convenient Maintenance for Combined Lightning and Surge Protection
Combined Type 1 + Type 2 surge protection is designed to handle both high-energy lightning currents characterised by a 10/350 µs waveform and transient surge currents characterised by an 8/20 µs waveform. The ABB OVR T1-T2 12.5-275s C QS provides the replaceable phase protection element for compatible OVR QuickSafe assemblies, helping restore their protective capability when an existing cartridge reaches the end of its service life.
The plug-in cartridge format allows maintenance personnel to replace the active protection module while retaining the existing SPD base and electrical connections. This helps reduce servicing time and avoids unnecessary rewiring, while the mechanical condition indicator provides an immediate visual indication of cartridge status.
