ABB OVR PV 40-1500H C U Surge Protective Device

ABB OVR PV 40-1500H C U is a three-pole Type 2 surge protective device (SPD) designed for the DC side of photovoltaic installations, delivering robust transient surge protection for PV strings and DC feeders rated up to 1500 V DC. It offers a maximum surge discharge current (Imax) of 40 kA per device and a DC operating voltage (Uc) up to 1500 V, making it suitable for contemporary high‑voltage PV designs such as 1,000 to 1,500 V systems and modern string inverters, with fast clamping performance to minimize voltage spikes seen by critical equipment. The unit is part of ABB's OVR PV family and is configured for DIN-rail mounting, enabling straightforward installation in standard electrical enclosures and combiner boxes, while aligning with ABB's broader solar protection portfolio for consistent coordination with other SPD modules and protection devices across a PV installation. This 40-1500H C U variant aligns with ABB's cataloged configurations for 3-phase PV arrays, delivering reliable protection for inverter input circuits, DC feeders, and upstream components in residential, commercial, and utility-scale projects, while maintaining compatibility with ABB's accessories and mounting options for streamlined integration in existing protection schemes.
