ABB OVRT2-15-150-CU Transient Voltage Surge Suppressor

ABB OVRT2-15-150-CU Transient Voltage Surge Suppressor is a Type 2 surge protective device (SPD) designed to clamp and divert transient overvoltages away from protected circuits, helping prevent damage from lightning and utility disturbances on AC power systems. Part of ABB’s OVR T2 family, this copper-terminal (CU) model is designed for DIN-rail mounting on 120/240 V split-phase distributions, a common arrangement in commercial and light-industrial panels. It is engineered to integrate with ABB surge-protection schemes for AC distribution, with a nominal system voltage of 240/120 V in typical installations, and it features replaceable cartridges to simplify field service. Replacement cartridge available: OVR T2 15-150 C U.
