The ABB OVR T1-T2 4L 12.5-275s P TS QS is a high-performance combined Type 1 + Type 2 surge protective device (SPD) designed to protect three-phase TN-S low-voltage electrical installations against lightning currents and transient overvoltages. Identified by ABB order code 2CTB815710R1100, this four-pole device forms part of the ABB OVR QuickSafe surge protection range and combines lightning-current discharge and secondary surge protection in one compact assembly.
Designed for 230/400 V AC TN-S distribution systems, the OVR T1-T2 4L 12.5-275s P TS QS provides an impulse current capability of 12.5 kA per pole using a 10/350 µs waveform and 50 kA total impulse current. It also provides a 20 kA nominal discharge current and 80 kA maximum discharge current, making it suitable for installations requiring protection against both lightning currents and switching or induced transient surges.
The device incorporates ABB QuickSafe technology, a Safety Reserve function, visual status indication and pluggable protection cartridges for straightforward maintenance. The TS version includes auxiliary signalling contacts for remote condition monitoring, while its four-module DIN-rail format integrates readily into main distribution boards and ABB System pro M compact installations.
Combined Type 1 + Type 2 SPDs are designed to handle both high-energy lightning currents and transient overvoltages within a coordinated protection device. The ABB OVR T1-T2 4L 12.5-275s P TS QS is tested with the 10/350 µs lightning-current waveform associated with Type 1 protection as well as the 8/20 µs discharge-current waveform used for Type 2 surge protection.
Its four-pole architecture is designed for TN-S installations, while the pluggable QuickSafe construction simplifies maintenance of the surge-protection system. Visual status indication provides local condition information, and the TS auxiliary contacts allow the SPD status to be monitored remotely by building-management, control or supervisory systems.
