Why Choose the ABB OVR T2-T3 3L 20-275 P TS QS Surge Protective Device?
The ABB OVR T2-T3 3L 20-275 P TS QS 2CTB803873R3500 is a three-line combined Type 2 and Type 3 surge protective device (SPD) designed for low-voltage three-phase electrical installations. Part of ABB's OVR QuickSafe range, it provides coordinated protection against transient overvoltages caused by indirect lightning effects and switching events.
The OVR T2-T3 3L 20-275 P TS QS has a maximum continuous operating voltage Uc of 275 V AC, a maximum discharge current Imax of 20 kA and a nominal discharge current In of 5 kA. Its voltage protection level Up is 0.85 kV, providing low residual voltage for enhanced protection of sensitive downstream equipment.
ABB's QuickSafe (QS) design uses replaceable pluggable protection cartridges for straightforward maintenance, while the TS configuration adds an auxiliary contact for remote status signalling. With three protected lines and a compact 53.4 mm DIN-rail width, the 2CTB803873R3500 provides a practical combination of surge protection, serviceability and remote condition monitoring.
Key Advantages
- Combined Type 2 + Type 3 surge protection for distribution systems and sensitive downstream equipment.
- Three protected lines for three-phase low-voltage applications.
- 20 kA maximum discharge current (Imax) for transient surge-current handling.
- Low 0.85 kV voltage protection level Up helps reduce transient voltage reaching connected equipment.
- TS auxiliary contact enables remote monitoring of surge protector status.
- QuickSafe pluggable construction allows individual protection cartridges to be replaced efficiently.

Combined Type 2 and Type 3 Protection with Remote Signalling
Combined Type 2 and Type 3 SPDs are designed to provide distribution-level surge-current handling together with enhanced voltage limitation close to sensitive electrical and electronic equipment. Type 2 performance safely discharges surge current characterised by an 8/20 µs waveform, while Type 3 protection provides additional protection against transient overvoltages with a low residual voltage.
The ABB OVR T2-T3 3L 20-275 P TS QS combines 20 kA Imax, 5 kA In and 0.85 kV Up across three protected lines. QuickSafe pluggable cartridges simplify servicing, while the TS auxiliary contact allows the SPD's condition to be integrated into compatible building-management, alarm or maintenance-monitoring systems.
Typical Applications
- Three-phase low-voltage electrical distribution systems.
- Main and intermediate electrical distribution boards.
- Commercial building electrical installations.
- Industrial control and distribution panels.
- Protection of automation and sensitive electronic equipment.
- Installations requiring combined Type 2 and Type 3 surge protection.
- Electrical systems requiring remote SPD condition monitoring.
