Why Choose the ABB OVR T2 80-275s P QS Surge Protection Device?
The ABB OVR T2 80-275s P QS, order code 2CTB815708R1200, is a pluggable Type 2 surge protection device (SPD) from the ABB OVR QuickSafe range. Designed for low-voltage electrical installations, it protects against transient overvoltages associated with indirect lightning and electrical switching events and is suitable for compatible 230/400 V AC TT, TN-C and TN-S systems.
This single-pole SPD provides a 20 kA nominal discharge current (In) and a high 80 kA maximum discharge current (Imax) with an 8/20 µs waveform. ABB also specifies a 6.25 kA impulse current (Iimp) with a 10/350 µs waveform, a maximum continuous operating voltage (Uc) of 275 V AC and a voltage protection level (Up) of 1.4 kV.
ABB's patented Safety Reserve system provides an additional protection stage to support continued basic surge protection and planned maintenance as the primary protection element reaches end of life. QuickSafe technology, an integrated thermal disconnector, end-of-life indication and pluggable construction make the OVR T2 80-275s P QS particularly suitable for distribution boards requiring high Type 2 discharge capacity and straightforward servicing.

High-Capacity Type 2 Protection with Safety Reserve Technology
Type 2 surge protection devices are designed to discharge currents generated by indirect lightning strikes and switching events that produce induced or conducted transient overvoltages on low-voltage power distribution networks. They are commonly installed in main distribution switchboards and subdistribution boards, where a suitably low voltage protection level helps reduce the transient stress applied to downstream electrical and electronic equipment.
The ABB OVR T2 80-275s P QS combines an 80 kA maximum 8/20 µs discharge current with ABB's patented Safety Reserve and QuickSafe technologies. The integrated end-of-life indicator and preventive-maintenance functionality assist with condition monitoring, while the pluggable OVR T2 80-275s C QS replacement cartridge allows the active protection element to be renewed without disturbing the permanently wired SPD base.
Typical Applications
- 230/400 V AC low-voltage electrical distribution systems.
- Compatible TT electrical installations.
