Why Choose the ABB OVR T1-T2 4L 12.5-440s P TS QS Surge Protective Device?
The ABB OVR T1-T2 4L 12.5-440s P TS QS is a high-performance combined Type 1 + Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations against lightning currents and transient overvoltages. Identified by ABB order code 2CTB815710R4000, this four-pole device forms part of the ABB OVR QuickSafe range and is designed for demanding three-phase power-distribution applications.
Designed for 400/690 V AC systems, the device provides an impulse current rating of 12.5 kA per pole using a 10/350 µs waveform, an 80 kA maximum discharge current and a 20 kA nominal discharge current. Its 440 V AC maximum continuous operating voltage makes it suitable for higher-voltage TN-S installations requiring coordinated lightning-current and transient-overvoltage protection.
The OVR T1-T2 4L 12.5-440s P TS QS incorporates ABB's QuickSafe reserve-varistor technology, which maintains a basic level of surge protection if the primary protection element reaches the end of its service life. Pluggable protection modules simplify maintenance, while the TS potential-free changeover contact enables remote monitoring of SPD status in industrial, commercial and infrastructure installations.

Combined Lightning and Surge Protection for 400/690 V Systems
Combined Type 1 + Type 2 SPDs provide coordinated protection against both high-energy lightning currents and transient overvoltages. The ABB OVR T1-T2 4L 12.5-440s P TS QS is tested for Type 1 lightning-current impulses using a 10/350 µs waveform while also providing Type 2 protection against transient currents characterised by an 8/20 µs waveform.
Its four-pole architecture is particularly suited to TN-S installations, while the QuickSafe reserve-varistor design provides additional protection availability by maintaining basic surge protection when the primary protection element reaches end of life. The pluggable construction simplifies maintenance, and the TS potential-free changeover contact enables remote condition monitoring.
Typical Applications
- Main electrical distribution switchboards.
- Three-phase TN-S electrical distribution systems.
- 400/690 V AC industrial power networks.
- Buildings equipped with external lightning protection systems.
