Why Choose the ABB OVR T2 40-350 P TS QS Surge Protective Device?
The ABB OVR T2 40-350 P TS QS is a single-pole Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations and connected equipment against transient overvoltages caused by indirect lightning effects and switching events. Part of the ABB OVR QuickSafe range, it combines high surge-current handling capability with a compact, pluggable DIN-rail design.
The OVR T2 40-350 P TS QS provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA using the standard 8/20 µs surge-current waveform. It is rated for 230 V AC nominal voltage, has a 350 V AC maximum continuous operating voltage (Uc) and provides a 1.5 kV voltage protection level (Up).
Its QuickSafe pluggable construction enables the protection cartridge to be replaced without replacing the complete installed base. An integrated status indicator supports straightforward local condition checking, while the TS remote signalling function provides one normally open and one normally closed auxiliary contact for external monitoring. At only 17.8 mm wide, the device occupies a single modular space in compatible distribution equipment.

Reliable QuickSafe Type 2 Protection for Low-Voltage Systems
Type 2 surge protective devices are designed to divert transient surge currents associated with indirect lightning effects and switching operations while limiting the overvoltage reaching downstream electrical and electronic equipment. They can be installed at the origin of an installation, in intermediate distribution boards or near terminal equipment as part of a coordinated surge protection system.
The ABB OVR T2 40-350 P TS QS combines 40 kA maximum discharge capability, 20 kA nominal discharge current and a 1.5 kV protection level with QuickSafe pluggable construction. Local status indication and integrated remote signalling make it particularly useful where surge protection condition needs to be monitored and maintained efficiently.
Typical Applications
- 230 V AC low-voltage electrical installations.
- 230/400 V AC distribution systems.
- TT, TN-C and TN-S networks.
- Main and intermediate distribution boards.
- Industrial switchboards and control panels.
- Commercial building electrical systems.
- Residential electrical installations.
- Protection close to sensitive terminal equipment.
- Installations requiring remote SPD status monitoring.
