Why Choose the ABB OVR PV T1-T2 5-1500 C QS Surge Protection Cartridge?
The ABB OVR PV T1-T2 5-1500 C QS, order code 2CTB812052R1500, is a replaceable Type 1+2 photovoltaic surge protection cartridge designed for ABB OVR PV surge protection assemblies operating at up to 1500 V DC. It provides combined lightning-current and transient overvoltage protection for the DC side of photovoltaic installations.
Designed for 1500 V DC photovoltaic systems, the OVR PV T1-T2 5-1500 C QS provides a total discharge current (Itotal) of 5 kA with a 10/350 µs waveform, a maximum discharge current (Imax) of 30 kA and a nominal discharge current (In) of 20 kA. Its 5 kV voltage protection level (Up) helps limit transient overvoltages reaching sensitive photovoltaic equipment.
The cartridge incorporates varistor technology, an integrated thermal disconnector and visual status indication. Its replaceable design allows a worn protection element to be exchanged without replacing the complete compatible SPD assembly, supporting straightforward maintenance of photovoltaic combiner boxes, DC distribution panels and inverter protection systems.

Replaceable Type 1+2 Protection for 1500 V Photovoltaic Systems
High-voltage photovoltaic installations can be exposed to transient overvoltages generated by lightning activity and electrical switching events. Type 1+2 photovoltaic surge protection combines lightning-current handling with protection against induced transient surges, helping reduce potentially damaging overvoltages on the DC side of a solar installation.
The ABB OVR PV T1-T2 5-1500 C QS is the replaceable protection cartridge specified for the ABB OVR PV T1-T2 5-1500 P QS assembly. Its 1500 V DC rating, 5 kA total 10/350 µs discharge current and 30 kA maximum 8/20 µs discharge current make it suitable for maintaining coordinated surge protection in high-voltage photovoltaic arrays, combiner boxes and inverter installations.
Typical Applications
- 1500 V DC photovoltaic installations.
- Replacement cartridge for ABB OVR PV T1-T2 5-1500 P QS assemblies.
