Why Choose the ABB OVR T2-T3 N 80-440 P QS Surge Protective Device?
The ABB OVR T2-T3 N 80-440 P QS is a high-capacity combined Type 2 and Type 3 neutral surge protective device (SPD) designed for neutral-to-earth protection in low-voltage electrical installations. As part of the ABB OVR QuickSafe surge protection range, this single-pole neutral module is intended for use in coordinated surge protection arrangements where dependable discharge of transient overvoltages between neutral and protective earth is required.
The OVR T2-T3 N 80-440 P QS provides a substantial maximum discharge current of 80 kA and a nominal discharge current of 30 kA using the 8/20 µs waveform. It also has an impulse current rating of 2 kA using the 10/350 µs waveform, providing robust neutral-to-earth surge handling within compatible Type 2 and Type 3 protection arrangements.
With a nominal voltage of 400 V AC, maximum continuous operating voltage of 440 V AC and voltage protection level of 1.4 kV, the device is suitable for higher-voltage low-voltage distribution applications. Its pluggable construction and compact single-module DIN-rail format make installation and replacement straightforward in commercial and industrial distribution boards.

High-Capacity Neutral-to-Earth Surge Protection
Neutral surge protective devices provide a controlled discharge path between neutral and protective earth during transient overvoltage events. The ABB OVR T2-T3 N 80-440 P QS is designed specifically for this role, providing an 80 kA maximum discharge capability to help prevent damaging voltage differences from developing between neutral and earth within coordinated surge protection systems.
Its combined Type 2 and Type 3 characteristics allow the device to support both distribution-level surge protection and protection closer to sensitive downstream equipment. The high discharge capability, 440 V AC Uc rating and pluggable construction make it suitable for demanding commercial and industrial electrical installations where reliable neutral-to-earth protection is required.
Typical Applications
- Neutral-to-earth surge protection in low-voltage distribution boards.
- Commercial and industrial electrical installations.
- Three-phase plus neutral surge protection assemblies.
- Electrical switchboards and distribution panels.
