ABB OVRT22L15150PU Overvoltage Protection Relay

ABB OVRT22L15150PU is a two-pole Type 2 surge protective device (SPD) from ABB’s System pro M compact OVRT family, designed to guard 50/60 Hz distribution networks from transient overvoltages. It provides L-L and L-G protection with a 175 V electrical rating, a short-circuit rating up to 200 kA (Ics), a peak surge current of 15 kA (Ipk), and a nominal discharge current of 5 kA (In). The unit is DIN rail‑mountable with plug‑in terminals housed in a gray NEMA 1 enclosure for indoor installation, measuring 35.6 mm wide by 64.8 mm deep by 90.5 mm high, and it operates from roughly −40 to 176 °F. A response time under 25 ns clamps transients quickly, while a built‑in status indicator helps verify protection at a glance. Intended for protecting downstream equipment such as PLCs, controllers, relays, and motor drives in commercial and light industrial panels, this ABB SPD delivers reliable surge protection for 230/240/400 V class distributions on 50/60 Hz systems and supports standard DIN rail mounting and plug‑in terminations for easy integration.
