Why Choose the ABB OVR T2 3L 40-275s P TS QS Surge Protection Device?
The ABB OVR T2 3L 40-275s P TS QS, order code 2CTB815704R0600, is a pluggable Type 2 surge protection device (SPD) designed to protect three-phase low-voltage electrical installations against transient overvoltages caused by indirect lightning and switching events. Part of the ABB OVR QuickSafe range, it combines high surge-discharge capability with ABB Safety Reserve technology for use in TN-C power distribution systems.
Designed for 230/400 V AC systems, the OVR T2 3L 40-275s P TS QS provides a 20 kA nominal discharge current (In) and a 40 kA maximum discharge current (Imax) with an 8/20 µs waveform. Its maximum continuous operating voltage (Uc) is 275 V AC, while its voltage protection level (Up) is 1.4 kV, helping limit transient voltages reaching downstream equipment.
The Safety Reserve system provides an additional level of protection and supports planned maintenance, while patented QuickSafe technology improves disconnection performance. The TS version includes remote signalling through one normally open and one normally closed auxiliary contact, complemented by local status indication and preventive-maintenance functionality.

Three-Phase Type 2 Protection with Safety Reserve Technology
Type 2 surge protection devices are designed to discharge surge currents generated by indirect lightning strikes and switching events that cause induced or conducted overvoltages on low-voltage power distribution networks. They are commonly installed in main distribution switchboards and subdistribution boards, where their low residual voltage helps protect downstream electrical and electronic equipment.
The ABB OVR T2 3L 40-275s P TS QS combines 40 kA maximum discharge capability with ABB's Safety Reserve and QuickSafe technologies. Its visual status indication, preventive-maintenance function and remote signalling contacts provide multiple ways to monitor SPD condition, helping maintenance teams identify when servicing or replacement is required while reducing the risk of unplanned loss of surge protection.
Typical Applications
- 230/400 V AC TN-C electrical distribution systems.
- Three-phase low-voltage distribution boards.
- Main electrical distribution switchboards.
- Subdistribution boards.
- Commercial building electrical systems.
- Industrial low-voltage electrical installations.
- Residential and multi-residential distribution systems.
- Installations requiring remote SPD status signalling.
- Protection against indirect lightning and switching-induced transient overvoltages.
