Why Choose the ABB OVR T2 3N 40-350 P QS Surge Protection Device?
The ABB OVR T2 3N 40-350 P QS, order code 2CTB803983R1100, is a pluggable Type 2 surge protection device (SPD) designed to protect low-voltage electrical installations against transient overvoltages caused by indirect lightning and electrical switching events. As part of the ABB OVR QuickSafe surge protection range, it provides coordinated surge protection for three-phase plus neutral electrical distribution systems.
Designed for 230/400 V AC TT and TN-S networks, this SPD uses a 3+1 protection configuration and provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA. Its overall voltage protection level (Up) of 1.7 kV, together with L-N and N-PE protection levels of 1.5 kV and 1.4 kV respectively, helps limit transient overvoltages reaching downstream equipment.
The OVR T2 3N 40-350 P QS has a 350 V AC maximum continuous operating voltage and uses replaceable phase and neutral protection cartridges. Its four-pole DIN rail format, visual status indication and 100 kA short-circuit withstand capability make it suitable for residential, commercial and industrial distribution boards requiring dependable three-phase surge protection.

Reliable Type 2 Protection for Three-Phase Electrical Systems
Type 2 surge protection devices are designed to protect low-voltage installations against transient overvoltages associated with indirect lightning and electrical switching events. They safely divert surge currents characterised by an 8/20 µs waveform while limiting the residual voltage that can reach connected electrical and electronic equipment.
The ABB OVR T2 3N 40-350 P QS combines a 3+1 protection arrangement with pluggable QuickSafe construction for TT and TN-S networks. Individual phase cartridges can be replaced with the ABB OVR T2 40-350 C QS, while the neutral protection element uses the OVR T2 N 80-350 C QS, simplifying maintenance without requiring replacement of the complete SPD assembly.
Typical Applications
- 230/400 V three-phase plus neutral electrical installations.
- TT and TN-S low-voltage distribution networks.
- Main and sub-distribution boards.
- Residential electrical distribution systems.
- Commercial building electrical installations.
- Industrial control and distribution panels.
- Protection of sensitive electrical and electronic equipment.
- Protection against indirect lightning-induced and electrical switching surges.
