  • Description

The ABB 2CTB812052R1000 (OVR PV T1-T2 5-1000 C QS) is a combined Type 1+2 surge protective device for 1000 V DC photovoltaic strings, supplied as the plug-in protection cartridge (C) for the QS base. It discharges up to 40 kA (8/20 µs) with a 3.8 kV voltage protection level across 2 protected poles, safeguarding PV inverters and combiner boxes against lightning-induced DC surges.

Selection Notes

Being the 'C' cartridge rather than the 'P' full device, this part replaces only the protection module once it reaches end-of-life, while the QS base plate and wiring stay in place — the reason to stock C units once the base is already installed. A 40 kA maximum discharge current and 3.8 kV protection level size it for 1000 V DC PV strings, not the higher-voltage strings that take the 1500 V-rated version. The visual status indicator lets a technician spot a depleted cartridge during a routine inspection without a multimeter check.
