Why Choose the ABB OVR T2 4L 80-275s P TS QS Surge Protection Device?
The ABB OVR T2 4L 80-275s P TS QS, order code 2CTB815708R1100, is a pluggable Type 2 surge protection device (SPD) from the ABB OVR QuickSafe range, designed to protect four-line low-voltage electrical installations against transient overvoltages caused by indirect lightning and switching events. ABB specifies four protected lines and suitability for 230/400 V AC TN-S distribution systems.
The OVR T2 4L 80-275s P TS QS provides a 20 kA nominal discharge current (In) and an exceptionally high 80 kA maximum discharge current (Imax) with an 8/20 µs waveform, together with a 6.25 kA impulse current (Iimp) using a 10/350 µs waveform. Its maximum continuous operating voltage (Uc) is 275 V AC, with ABB specifying a voltage protection level of 1.4 kV L-PE.
ABB's patented Safety Reserve system and QuickSafe technology support protection continuity and planned maintenance, while the integrated thermal disconnector and end-of-life indication provide clear local condition monitoring. The TS version also includes one normally open and one normally closed auxiliary contact for remote status signalling, making the device well suited to installations where SPD condition needs to be integrated into a monitoring or alarm system.

High-Capacity Type 2 Protection with Safety Reserve Technology
Type 2 surge protection devices are designed to discharge transient currents generated by indirect lightning and switching events that create induced or conducted overvoltages on low-voltage distribution networks. They are commonly installed in main distribution switchboards and subdistribution boards, helping prevent damaging transient voltages from reaching downstream electrical and electronic equipment.
The ABB OVR T2 4L 80-275s P TS QS combines an 80 kA maximum 8/20 µs discharge current with ABB's patented Safety Reserve and QuickSafe technologies. Local end-of-life indication, preventive-maintenance functionality and remote signalling provide several ways to monitor SPD condition, while the pluggable OVR T2 80-275s C QS cartridges allow protection elements to be replaced without disturbing the permanently wired SPD base.
Typical Applications
- 230/400 V AC TN-S electrical distribution systems.
- Four-line low-voltage power distribution installations.
- Main electrical distribution switchboards.
- Subdistribution boards.
- Commercial building electrical systems.
- Industrial low-voltage electrical installations.
- Installations requiring high Type 2 surge-discharge capability.
- Installations requiring remote SPD condition signalling.
- Protection of sensitive electrical and electronic equipment.
- Protection against indirect lightning and switching-induced transient overvoltages.
