Why Choose the ABB OVR PV T1-T2 5-1500 P QS Photovoltaic Surge Protective Device?
The ABB OVR PV T1-T2 5-1500 P QS is a combined Type 1 + Type 2 photovoltaic surge protective device (SPD) designed to protect high-voltage DC solar installations against damaging transient overvoltages and lightning surge currents. Identified by ABB order code 2CTB812050R1500, it is specifically engineered for photovoltaic applications with DC system voltages up to 1500 V DC.
As part of the ABB OVR PV QuickSafe surge protection range, this SPD provides coordinated Type 1 and Type 2 protection in a compact DIN rail format. It protects both L+ and L− photovoltaic conductors and uses pluggable protection cartridges, allowing damaged or end-of-life modules to be replaced without changing the complete installed base.
The OVR PV T1-T2 5-1500 P QS provides an impulse discharge current (Iimp) of 5 kA per protected path using a 10/350 µs waveform, a nominal discharge current (In) of 20 kA and a total 8/20 µs discharge capability of 30 kA. Its 5 kV voltage protection level and photovoltaic-specific DC design make it suitable for protecting solar arrays, combiner boxes, inverter inputs and associated DC distribution equipment.

Reliable Lightning and Surge Protection for Photovoltaic Systems
Photovoltaic installations can be particularly exposed to transient overvoltages because of their extensive DC cabling and outdoor solar arrays. Combined Type 1 and Type 2 SPDs are designed to handle both lightning-current impulses and induced or switching surges, limiting the transient voltage transmitted towards photovoltaic inverters and other sensitive DC equipment.
The ABB OVR PV T1-T2 5-1500 P QS is designed specifically for modern high-voltage PV installations. Its 1500 V DC capability, 10/350 µs lightning-current performance and pluggable QuickSafe construction provide a practical solution for protecting photovoltaic strings, combiner equipment and inverter DC inputs while simplifying inspection and maintenance.
Typical Applications
- 1500 V DC photovoltaic installations.
- Utility-scale solar photovoltaic arrays.
- Commercial and industrial rooftop PV systems.
- 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.
