The ABB OVR T1-T2 3L 12.5-440s P TS QS, order code 2CTB815710R3500, 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. Part of the ABB OVR QuickSafe surge protection range, it combines lightning-current protection and Type 2 surge protection in a compact three-pole assembly for industrial, commercial and infrastructure electrical distribution systems.
The 3L configuration protects all three phase conductors and is intended for appropriate three-phase electrical networks. Its pluggable construction enables individual protection cartridges to be replaced when required, while integrated mechanical status indication provides straightforward local condition checking. The TS remote signalling contact also allows the SPD's operating status to be monitored from an external control, alarm or building-management system.
With a maximum continuous operating voltage (Uc) of 440 V AC and an impulse current (Iimp) of 12.5 kA for the 10/350 µs lightning-current waveform, the OVR T1-T2 3L 12.5-440s P TS QS provides robust protection for higher-voltage three-phase systems. Its combined Type 1+2 performance allows a single coordinated device to handle lightning-current impulses as well as lower-energy transient overvoltages caused by indirect lightning and electrical switching.
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. The ABB OVR T1-T2 3L 12.5-440s P TS QS combines these functions to provide coordinated protection for three-phase low-voltage distribution systems.
The OVR QuickSafe design also supports straightforward maintenance throughout the installation's service life. Pluggable protection cartridges can be replaced when necessary, mechanical indicators allow local inspection, and the TS remote signalling contact enables the SPD condition to be integrated into remote alarm or monitoring systems.
