Surge protective devices (SPD) Type 2 protect low-voltage electrical installations against transient overvoltage's caused by indirect lightning strikes and switching operations. The ABB OVR T2 3N 80-275s P TS QS is a four-pole, plug-in surge protective device designed for three-phase electrical distribution systems with neutral. It is tested according to IEC 61643-11 / EN 61643-11 and is compatible with the ABB System pro M compact series. The device incorporates reserve-varistor technology to maintain basic protection even when the primary varistor reaches the end of its service life. The TS version includes an auxiliary signaling contact for remote status monitoring. It supports TT and TN-S earthing systems and is designed for 35 mm DIN-rail mounting.
