Why Choose the ABB OVR T2 3L 80-275s P TS QS Surge Protective Device?
The ABB OVR T2 3L 80-275s P TS QS, order code 2CTB815708R0600, is a high-capacity Type 2 surge protective device (SPD) designed for three-phase 230/400 V AC TN-C electrical systems. Installed in main distribution boards or sub-distribution boards, it protects electrical installations and connected equipment against transient overvoltages caused by indirect lightning effects and switching events.
The OVR T2 3L 80-275s P TS QS provides three protected L-PEN paths with a maximum continuous operating voltage of 275 V AC. It has a nominal discharge current In of 20 kA and a high maximum discharge current Imax of 80 kA using the 8/20 µs waveform, together with an impulse-current capability Iimp of 6.25 kA using the 10/350 µs waveform.
ABB's patented Safety Reserve system provides a preventive-maintenance function that helps extend protection availability, while QuickSafe technology supports dependable end-of-life disconnection. Pluggable construction, visual status indication and TS remote signalling with one normally open and one normally closed auxiliary contact make this SPD particularly suitable for demanding commercial and industrial installations where local and remote condition monitoring are required.

High-Capacity Type 2 Protection with Safety Reserve Technology
Type 2 SPDs are designed to discharge surge currents associated with indirect lightning effects and switching operations before damaging transient voltages reach connected equipment. With an 80 kA maximum 8/20 µs discharge-current rating, the ABB OVR T2 3L 80-275s P TS QS provides particularly high surge-current capability while maintaining a low 1.4 kV protection level for downstream equipment.
ABB's patented Safety Reserve system is designed to extend protection availability and support planned preventive maintenance, helping reduce the risk of downtime. The pluggable architecture simplifies replacement, while local status indication and TS auxiliary contacts allow maintenance personnel to monitor the SPD both at the switchboard and through suitable remote monitoring or alarm equipment.
Typical Applications
- Three-phase 230/400 V AC TN-C electrical systems.
- Main low-voltage distribution switchboards.
- Industrial sub-distribution boards.
- Commercial building electrical panels.
- Manufacturing and process-control installations.
- Protection of industrial automation and electronic equipment.
- Installations exposed to significant transient surge currents.
- Applications requiring preventive SPD maintenance indication.
- Systems requiring remote surge-protection status monitoring.
