Why Choose the ABB OVR PV T1-T2 5-1500 P TS QS Surge Protective Device?
The ABB OVR PV T1-T2 5-1500 P TS QS is a high-performance combined Type 1 and Type 2 photovoltaic surge protective device (SPD) designed to protect DC solar installations against transient overvoltages and lightning surge currents. Engineered specifically for photovoltaic applications, it supports DC systems up to 1500 V and provides coordinated surge protection for PV arrays, combiner boxes, inverters and associated DC distribution equipment.
The OVR PV T1-T2 5-1500 P TS QS provides an impulse current Iimp of 5 kA using the 10/350 µs waveform, a nominal discharge current In of 20 kA and a maximum discharge current Imax of 30 kA using the 8/20 µs waveform. Its 5 kV voltage protection level helps limit transient voltages reaching downstream photovoltaic equipment.
Designed with ABB's QuickSafe technology, the device features pluggable protection cartridges, visual status indication and TS auxiliary signalling for remote monitoring. Its 1500 V DC rating, two protected lines and compact DIN-rail construction make it particularly suitable for modern utility-scale, commercial and industrial photovoltaic installations.
