Why Choose the ABB OVR PV T1-T2 12.5-1000 P TS QS Surge Protection Device?
The ABB OVR PV T1-T2 12.5-1000 P TS QS, order code 2CTB812121R1000, is a pluggable Type 1+2 photovoltaic surge protection device (SPD) designed to protect the DC side of solar PV installations against lightning currents and transient overvoltages. As part of the ABB OVR PV QuickSafe range, it combines Type 1 lightning-current protection with Type 2 surge protection for demanding photovoltaic applications.
Designed for 1000 V DC photovoltaic systems, the OVR PV T1-T2 12.5-1000 P TS QS uses a 1+1 DC protection configuration and provides a total discharge current (Itotal) of 12.5 kA and an impulse current (Iimp) of 6.25 kA with a 10/350 µs waveform. It also provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA with an 8/20 µs waveform.
With a 1100 V DC maximum continuous operating voltage (Ucpv) and a 3.8 kV voltage protection level (Up), this SPD is engineered for modern high-voltage photovoltaic systems. The TS version includes auxiliary remote signalling, while visual status indication and pluggable QuickSafe construction support convenient monitoring, inspection and maintenance in PV combiner boxes, DC distribution panels and inverter protection applications.

High-Capacity Type 1+2 Protection with Remote Monitoring for 1000 V PV Systems
Photovoltaic installations can be exposed to high-energy lightning currents and induced transient overvoltages because solar arrays are often installed in exposed locations and connected through extensive DC cabling. Type 1+2 photovoltaic SPDs combine lightning-current handling with Type 2 surge protection, helping protect sensitive DC equipment against both 10/350 µs lightning impulses and 8/20 µs transient surge currents.
The ABB OVR PV T1-T2 12.5-1000 P TS QS combines a 12.5 kA total 10/350 µs discharge capability with a 40 kA maximum 8/20 µs discharge current. Its remote signalling facility allows SPD status to be integrated into monitoring or alarm systems, making it particularly suitable for photovoltaic installations where the condition of surge protection equipment needs to be monitored without direct visual inspection.
Typical Applications
- 1000 V DC photovoltaic installations.
- Commercial and industrial solar PV systems.
- Utility-scale photovoltaic power installations.
- Solar PV combiner boxes.
- Photovoltaic DC distribution panels.
- PV inverter DC input protection.
- PV systems requiring remote SPD status signalling.
- Installations requiring combined Type 1 and Type 2 surge protection.
- Protection against lightning currents and induced transient overvoltages.
