The OVR NE12 is a multistage protector with fast acting varistor (MOV) and EMI/RFI noise attenuation filter to limit overvoltage to values compatible with the sensitive equipment connected to the network. In addition to the OVR NE12, ABB recommends adding OVR DIN rail SPDs at branch panels and equipment, creating a multi-level approach to protection

The OVR NE12 is suitable for protection for all types of facilities and operations. It is designed with a NEMA type 12 enclosure, rated as type 2 SPD, requiring indoor installation on the load side of the main breaker or fuse.
