Why Choose the ABB OVR T2-T3 1N 20-275 P TS QS Surge Protection Device?
The ABB OVR T2-T3 1N 20-275 P TS QS, order code 2CTB803972R1300, is a pluggable Type 2+3 surge protection device (SPD) designed to protect low-voltage electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning and electrical switching events. As part of the ABB OVR QuickSafe surge protection range, it combines distribution-level surge protection with a low residual voltage level for equipment installed further downstream.
Designed for 230 V single-phase plus neutral TT and TN-S networks, this SPD uses a 1+1 protection configuration and provides a maximum discharge current (Imax) of 20 kA, a nominal discharge current (In) of 5 kA and a voltage protection level (Up) of 1.4 kV. Its Type 2+3 design makes it suitable for installation in intermediate distribution boards and close to sensitive terminal equipment.
The OVR T2-T3 1N 20-275 P TS QS has a 275 V AC maximum continuous operating voltage and features pluggable protection cartridges, visual status indication and an integrated remote signalling auxiliary contact. DIN rail mounting and its compact two-module format make it straightforward to incorporate into residential, commercial and industrial electrical distribution panels.
Key Advantages
Combined Type 2+3 surge protection for low-voltage electrical installations.
20 kA maximum discharge current (Imax) with an 8/20 µs waveform.
5 kA nominal discharge current (In) with an 8/20 µs waveform.
1.4 kV voltage protection level (Up) helps limit transient voltage reaching connected equipment.
275 V AC maximum continuous operating voltage for 230 V single-phase applications.
Integrated remote signalling auxiliary contact for monitoring SPD status.
Pluggable cartridges simplify inspection, maintenance and replacement.
Suitable for TT and TN-S distribution networks.

Reliable Type 2+3 Protection for Sensitive Equipment
Type 2+3 surge protection devices are designed to limit transient overvoltages within low-voltage electrical installations. Their Type 2 capability safely discharges surge currents characterised by an 8/20 µs waveform, while Type 3 protection provides additional protection close to sensitive terminal equipment against voltage impulses characterised by a 1.2/50 µs waveform.
The ABB OVR T2-T3 1N 20-275 P TS QS combines these protection functions with pluggable cartridges and remote status signalling. This makes it particularly suitable for installations where effective surge protection, straightforward maintenance and remote indication of protection status are required.
Typical Applications
230 V single-phase plus neutral electrical installations.
TT and TN-S low-voltage distribution networks.
Residential electrical distribution boards.
Commercial building electrical installations.
Industrial control and distribution panels.
Intermediate distribution boards.
Protection of sensitive electrical and electronic equipment.
Protection against indirect lightning-induced and switching surges.
