The ABB OVR T2 3N 40-440 P TS QS is a high-performance Type 2 surge protective device (SPD) designed to protect three-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 high surge discharge capability, pluggable protection cartridges and remote status signalling for dependable protection in commercial and industrial electrical systems.
Designed for TN-S and TT networks in a 3+1 configuration, the OVR T2 3N 40-440 P TS QS provides a maximum discharge current of 40 kA and a nominal discharge current of 20 kA using the standard 8/20 µs surge waveform. It is suitable for nominal systems up to 400/690 V AC and has a maximum continuous operating voltage of 440 V AC.
The TS remote signalling function provides one normally open and one normally closed auxiliary contact, allowing the SPD's operating condition to be integrated into monitoring and alarm systems. Combined with visual status indication, replaceable cartridges, IP20 protection and DIN-rail mounting, this device provides a practical surge protection solution for distribution boards, switchgear and automation panels.
Type 2 surge protective devices are designed to discharge surge currents generated by indirect lightning strikes and switching events before damaging transient voltages reach connected equipment. The ABB OVR T2 3N 40-440 P TS QS provides coordinated protection for three-phase plus neutral systems, helping safeguard switchgear, drives, PLCs, automation equipment and other sensitive electrical loads.
The TS version adds remote operating-status signalling through one normally open and one normally closed contact. These contacts can be connected to building management systems, PLCs, alarm circuits or other monitoring equipment, allowing maintenance personnel to identify a change in SPD status without relying solely on local visual inspection.
