Why Choose the ABB OVR PV T1-T2 10-1500 P TS QS Photovoltaic Surge Protective Device?
The ABB OVR PV T1-T2 10-1500 P TS QS is a combined Type 1 + Type 2 photovoltaic surge protective device (SPD) engineered to protect high-voltage DC solar installations against lightning-current impulses and transient overvoltages. Identified by ABB order code 2CTB812101R1500, it is designed specifically for photovoltaic networks with a maximum continuous operating voltage of 1500 V DC.
As part of the ABB OVR PV QuickSafe range, this device uses a 1+1 DC protection configuration and combines lightning-current withstand capability with Type 2 surge-voltage limitation. Its pluggable construction allows protection cartridges to be replaced without changing the complete installed base, while optical status indication provides straightforward local condition checking.
The OVR PV T1-T2 10-1500 P TS QS provides a 5 kA impulse current (Iimp) per protected path and a 10 kA total discharge current (Itotal) using a 10/350 µs waveform. It also provides a 20 kA nominal discharge current (In), a 30 kA maximum discharge current (Imax) using an 8/20 µs waveform and a 5 kV voltage protection level (Up). The integrated TS remote signalling contact enables SPD condition monitoring from a remote control or monitoring system.

Reliable Lightning and Surge Protection for 1500 V DC Photovoltaic Systems
Large photovoltaic arrays can be particularly exposed to lightning-related and induced transient overvoltages because of their extensive outdoor DC cabling. Combined Type 1 and Type 2 SPDs provide protection against the high-energy 10/350 µs lightning-current waveform while also limiting the voltage rise associated with 8/20 µs transient surge currents.
The ABB OVR PV T1-T2 10-1500 P TS QS combines these protection functions in a photovoltaic-specific 1500 V DC design. Its pluggable QuickSafe construction facilitates maintenance, while local optical indication and TS remote signalling provide convenient monitoring of SPD condition in commercial, industrial and large-scale solar power installations.
Typical Applications
- 1500 V DC photovoltaic installations.
- Large-scale and utility solar power plants.
- Commercial and industrial photovoltaic systems.
- PV string and array combiner boxes.
- Photovoltaic DC distribution boards.
- Protection of solar inverter DC inputs.
- PV installations requiring combined Type 1 and Type 2 protection.
- Solar systems requiring remote SPD condition monitoring.
