Why Choose the ABB OVR T2 3N 80-275s P TS QS Surge Protective Device?
The ABB OVR T2 3N 80-275s P TS QS, order code 2CTB815708R0800, is a high-capacity Type 2 surge protective device (SPD) designed for three-phase plus neutral 230/400 V AC TN-S and TT electrical systems. It is suitable for installation at the origin of an installation, in intermediate distribution boards and close to terminal equipment, providing protection against transient overvoltages generated by indirect lightning strikes and electrical switching events.
The OVR T2 3N 80-275s P TS QS uses a 3+1 protection configuration with four protected lines and a maximum continuous operating voltage Uc of 275 V AC. It provides a nominal discharge current In of 30 kA and a maximum discharge current Imax of 80 kA using the 8/20 µs waveform, together with an impulse-current capability Iimp of 6.25 kA using the 10/350 µs waveform.
ABB's patented Safety Reserve system provides additional protection availability and supports planned preventive maintenance, while integrated QuickSafe technology provides dependable thermal disconnection. Pluggable phase and neutral cartridges, end-of-life indication and TS remote signalling make this SPD particularly well suited to demanding commercial and industrial installations where straightforward servicing and remote condition monitoring are required.

High-Capacity Safety Reserve Protection for Three-Phase Plus Neutral Systems
Type 2 SPDs are designed to discharge surge currents generated by indirect lightning strikes and switching operations before damaging transient voltages reach connected equipment. With a 30 kA nominal discharge current, 80 kA maximum discharge current and coordinated 3+1 topology, the ABB OVR T2 3N 80-275s P TS QS provides robust surge protection for demanding three-phase plus neutral TN-S and TT installations.
ABB's patented Safety Reserve system provides an additional protection stage so the SPD is not completely disconnected from the network when the primary protection element reaches end of life. This helps maintain basic protection until maintenance can be performed. Combined with individually replaceable cartridges, end-of-life indication and TS auxiliary contacts, the design supports efficient preventive maintenance and remote SPD condition monitoring.
