The OVR NE12 enclosed surge protective device (SPD) from ABB is a multistage protector with fast acting metal oxide varistors (MOV) and an EMI/RFI noise attenuation filter to limit overvoltage to values compatible with the sensitive equipment connected to the network. Extensive damage and expensive repairs can result from transient surges if surge protection is not present. The OVR NE12 is a UL 1449 3rd Edition certified Type 2 SPD contained within a NEMA Type 12 enclosure, designed for installation indoors on the load side of the main breaker or fuse. The new SDP uses MOV technology to achieve a high level of protection performance, and allows for ease of module replacement. Each OVR NE12 comes standard with status lights, alarm, auxiliary contacts, EMI filtering, and a fused disconnect. An optional surge counter/diagnostic LCD that records the date and time of surges 2 kA and above is also available.
