Why Choose the ABB OVR PV T1-T2 5-1000 P TS QS Photovoltaic Surge Protective Device?
The ABB OVR PV T1-T2 5-1000 P TS QS is a combined Type 1 + Type 2 photovoltaic surge protective device (SPD) designed to protect DC solar installations against lightning currents and transient overvoltages. Identified by ABB order code 2CTB812051R1000, it is specifically developed for photovoltaic applications with DC system voltages up to 1000 V DC.
As part of the ABB OVR PV QuickSafe surge protection range, the device combines Type 1 lightning-current protection with Type 2 surge protection in a compact, pluggable DIN rail assembly. Its photovoltaic-specific design protects the positive and negative DC conductors, while replaceable cartridges simplify servicing after a protection module reaches the end of its operating life.
The OVR PV T1-T2 5-1000 P TS QS provides an impulse discharge current (Iimp) of 5 kA using a 10/350 µs waveform and a nominal discharge current (In) of 20 kA using an 8/20 µs waveform. The integrated TS remote signalling contact enables the SPD status to be monitored remotely, making it particularly suitable for commercial, industrial and utility photovoltaic installations.

Reliable Lightning and Surge Protection for Photovoltaic Systems
Photovoltaic systems can be particularly vulnerable to transient overvoltages because solar arrays and their associated DC cabling are often distributed over large outdoor areas. Lightning events can introduce both direct lightning-current components and induced surges into these circuits, placing sensitive inverter electronics and other DC equipment at risk.
The ABB OVR PV T1-T2 5-1000 P TS QS combines Type 1 and Type 2 protection in a photovoltaic-specific design. Its pluggable QuickSafe modules facilitate maintenance, while the TS signalling contact allows the condition of the SPD to be incorporated into remote monitoring systems for improved maintenance visibility across commercial and utility-scale solar installations.
Typical Applications
- 1000 V DC photovoltaic installations.
- Commercial and industrial solar PV systems.
- Utility-scale photovoltaic arrays.
- Photovoltaic string and array combiner boxes.
- DC distribution boards for solar installations.
- Protection of photovoltaic inverter DC inputs.
- PV installations requiring combined Type 1 and Type 2 lightning and surge protection.
- Solar installations requiring remote SPD condition monitoring.
