Why Choose the ABB OVR PV T1-T2 5-1000 P QS Surge Protection Device?
The ABB OVR PV T1-T2 5-1000 P QS, order code 2CTB812050R1000, is a pluggable Type 1+2 photovoltaic surge protection device (SPD) designed to protect DC photovoltaic installations against lightning currents and transient overvoltages. As part of the ABB OVR PV surge protection range, it provides coordinated protection for solar PV systems operating at nominal voltages up to 1000 V DC.
Designed specifically for photovoltaic applications, the OVR PV T1-T2 5-1000 P QS uses a 1+1 DC protection configuration and protects both L+ and L− lines. It provides an impulse current (Iimp) of 5 kA with a 10/350 µs waveform, a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA, providing effective protection against both lightning-current impulses and induced surge events.
With a 1000 V DC nominal system voltage, 1100 V DC maximum continuous operating voltage (Ucpv) and a 3.8 kV voltage protection level (Up), this SPD is engineered for modern photovoltaic arrays and DC distribution systems. Its pluggable three-module design, integrated thermal disconnector and visual status indication support straightforward installation, inspection and maintenance.

Reliable Lightning and Surge Protection for Photovoltaic Systems
Photovoltaic installations can be exposed to transient overvoltages generated by lightning activity and switching events, particularly where long DC cables connect exposed solar arrays to inverters and other electrical equipment. Type 1+2 photovoltaic SPDs combine lightning-current handling with surge protection to help limit damaging transient voltages within the DC side of a solar installation.
The ABB OVR PV T1-T2 5-1000 P QS is designed specifically for high-voltage PV networks. Its 1100 V DC continuous operating capability, 5 kA 10/350 µs impulse-current rating and 40 kA maximum discharge current provide coordinated protection for photovoltaic arrays, combiner boxes and inverter DC inputs, while its pluggable cartridges simplify ongoing system maintenance.
