Why Choose the ABB OVR T2 1N 40-320 P TS U Surge Protective Device?
The ABB OVR T2 1N 40-320 P TS U 2CTB802342R2500 is a Type 2 pluggable surge protective device (SPD) designed for single-phase low-voltage electrical networks. Part of ABB's OVR surge protection range, it helps protect electrical installations and connected equipment against transient overvoltages caused by lightning-related disturbances and switching events.
Designed for 277 V AC nominal systems, the OVR T2 1N 40-320 P TS U has a maximum continuous operating voltage of 320 V. It provides a maximum discharge current Imax of 40 kA and a nominal discharge current In of 20 kA, with surge-current performance based on the standard 8/20 µs waveform.
The 1N configuration provides two protected lines for single-phase applications, while the TS version incorporates remote signalling for monitoring the status of the surge protective device. With a 1.2 kV voltage protection rating and pluggable construction, the 2CTB802342R2500 provides a practical surge protection solution for commercial, industrial and building electrical distribution systems.

Type 2 Surge Protection with Remote Status Signalling
Type 2 surge protective devices are installed in low-voltage distribution systems to limit transient overvoltages and divert surge current before damaging voltage levels can reach downstream equipment. They are widely used in distribution boards and control panels as part of a coordinated approach to electrical and electronic equipment protection.
The ABB OVR T2 1N 40-320 P TS U combines 40 kA Imax and 20 kA In surge-current capabilities with a 320 V maximum continuous operating voltage. The TS remote signalling facility enables the SPD's status to be incorporated into suitable monitoring arrangements, while its pluggable construction supports efficient maintenance and replacement.
Typical Applications
- 277 V AC single-phase electrical distribution systems.
- Commercial building distribution boards.
- Industrial electrical panels and switchboards.
