Why Choose the ABB OVR T2 1N 40-350 P TS QS Surge Protective Device?
The ABB OVR T2 1N 40-350 P TS QS is a high-performance Type 2 surge protective device (SPD) designed to protect single-phase plus neutral low-voltage electrical installations against transient overvoltages caused by indirect lightning effects and switching events. As part of the ABB OVR QuickSafe surge protection range, it combines dependable surge suppression, pluggable protection cartridges and remote status signalling for residential, commercial and industrial electrical systems.
Designed for TT and TN-S networks, the OVR T2 1N 40-350 P TS QS provides a nominal discharge current of 20 kA and a maximum discharge current of 40 kA using the standard 8/20 µs surge waveform. Its two-pole configuration protects the phase and neutral paths, while a short-circuit withstand capability of 100 kA supports installation in demanding low-voltage distribution systems.
With a nominal system voltage of 230/400 V AC, maximum continuous operating voltage of 350 V AC and voltage protection levels of 1.5 kV L-N and 1.4 kV N-PE, this SPD provides effective protection for sensitive downstream equipment. The TS auxiliary signalling contacts provide one normally open and one normally closed contact for remote status monitoring, while the pluggable design simplifies servicing and cartridge replacement.

Reliable Surge Protection with Remote Status Monitoring
Type 2 surge protective devices are used to limit transient overvoltages before they can damage electrical and electronic equipment. The ABB OVR T2 1N 40-350 P TS QS safely diverts surge currents away from protected circuits, helping safeguard building systems, automation equipment, controls, power supplies and other sensitive loads against the effects of indirect lightning and switching surges.
The TS version adds remote operating-status signalling through one normally open and one normally closed auxiliary contact. These contacts can be incorporated into monitoring, alarm or building-management systems, allowing maintenance personnel to monitor SPD condition remotely while the device's local status indicator provides convenient visual inspection at the distribution board.
Typical Applications
- 230/400 V AC TT and TN-S distribution systems.
- Residential and commercial distribution boards.
- Industrial electrical and automation panels.
- Building electrical distribution systems.
- Protection of PLCs, controls and sensitive electronic equipment.
- Switchgear and power distribution assemblies.
- Installations requiring remote SPD status monitoring.
