Why Choose the ABB OVR T1-T2 12.5-440s C QS Replacement Cartridge?
The ABB OVR T1-T2 12.5-440s C QS, order code 2CTB815710R5500, is a replacement surge protection cartridge for compatible ABB OVR T1-T2 QuickSafe pluggable surge protective devices. Designed as part of ABB's combined Type 1 and Type 2 surge protection system, it restores the replaceable protection element without requiring the complete installed SPD base to be changed.
The cartridge is designed for compatible 440 V AC OVR T1-T2 QuickSafe assemblies and provides combined lightning-current and transient-overvoltage protection. Its plug-in format makes planned maintenance faster and helps reduce disruption when a protection cartridge reaches the end of its service life.
With a maximum continuous operating voltage (Uc) of 440 V AC and an impulse current (Iimp) of 12.5 kA for the 10/350 µs lightning-current waveform, the OVR T1-T2 12.5-440s C QS is engineered for demanding surge protection duties. QuickSafe technology provides clear condition indication and supports reliable end-of-life management in compatible ABB OVR installations.
Key Advantages
- Genuine ABB replacement cartridge for compatible OVR T1-T2 QuickSafe surge protective devices.

Reliable Replacement Protection for ABB OVR QuickSafe SPDs
Pluggable surge protective devices allow the active protection element to be replaced separately from the permanently wired base. The ABB OVR T1-T2 12.5-440s C QS provides this replaceable element for compatible 440 V AC OVR T1-T2 QuickSafe assemblies, helping restore combined Type 1 and Type 2 protection following end-of-life indication or scheduled maintenance.
Using the correct ABB replacement cartridge preserves the intended electrical characteristics and mechanical compatibility of the installed surge protection assembly. The plug-in design also reduces maintenance work because the existing compatible SPD base and its fixed wiring can remain installed while the cartridge is exchanged.
Typical Applications
- Replacement cartridge for compatible ABB OVR T1-T2 12.5-440s SPDs.
- Maintenance of main low-voltage electrical distribution boards.
- Industrial control and power distribution panels.
- Commercial and industrial electrical installations.
- Buildings requiring combined Type 1 and Type 2 surge protection.
- Preventative maintenance of ABB QuickSafe surge protection systems.
- Replacement of an end-of-life compatible surge protection cartridge.
