The ABB OVR T2 3N 80‑275S P TS QS is a Type 2 surge protective device (SPD) designed to protect low‑voltage electrical systems from transient overvoltages caused by lightning strikes and switching surges. It is intended for installation near the service entrance or load distribution point on a DIN‑rail and is compatible with three‑phase TN‑S and TT power distribution systems. The device features multiple protection stages to divert surge energy safely to ground, limiting the voltage seen by downstream equipment. It incorporates visual and auxiliary signalling for operational and maintenance feedback and is suitable for residential, commercial, and industrial distribution panels where enhanced surge protection is required.
