Why Choose the ABB OVR T1-T2 3L 12.5-275s P TS QS Surge Protective Device?
The ABB OVR T1-T2 3L 12.5-275s P TS QS, order code 2CTB815710R0600, is a combined Type 1 and Type 2 surge protective device (SPD) designed to protect three-phase low-voltage electrical installations against lightning currents and transient overvoltages. As part of the ABB OVR QuickSafe surge protection range, it combines lightning-current protection and Type 2 surge protection in a compact DIN-rail-mounted assembly for industrial and commercial power distribution systems.
The 3L configuration provides protection for all three phase conductors, making this SPD suitable for appropriate three-phase electrical networks. Its pluggable construction supports straightforward maintenance and replacement, while the TS remote signalling contact enables the operating condition of the surge protector to be monitored remotely. Integrated mechanical status indication also allows convenient local inspection.
With a maximum continuous operating voltage (Uc) of 275 V AC and an impulse discharge current (Iimp) of 12.5 kA per pole using a 10/350 µs waveform, the OVR T1-T2 3L 12.5-275s P TS QS is engineered to handle high-energy lightning-related surges. Its combined Type 1+2 classification provides coordinated protection against both lightning-current impulses and lower-energy transient overvoltages within three-phase distribution systems.

Combined Lightning and Surge Protection for Three-Phase Systems
Type 1 surge protective devices are designed to discharge high-energy lightning currents that can enter an electrical installation, while Type 2 protection limits transient overvoltages associated with indirect lightning effects and electrical switching operations. By combining these functions, the ABB OVR T1-T2 3L 12.5-275s P TS QS provides coordinated protection within a single three-pole DIN-rail-mounted assembly.
The OVR QuickSafe range is designed for dependable protection and practical maintenance in modern electrical distribution systems. Pluggable modules simplify replacement when required, while mechanical status indication and the TS remote signalling contact allow the condition of the SPD to be checked locally or incorporated into a remote monitoring system.
Typical Applications
- Three-phase low-voltage electrical distribution systems.
- Main distribution boards requiring combined Type 1 and Type 2 protection.
- Industrial control and power distribution panels.
- Commercial and industrial buildings.
- Buildings equipped with external lightning protection systems.
