ABB OVR NE12 Product Guide
Product introduction
Devices
Surge Protective
Introduction
The OVR NE12 enclosed surge protective device (SPD) is the latest addition to ABB’s extensive range of surge protection products. It is
designed to be installed at the service entrance, thereby protecting the entire facility from the harmful effects of transient surges. These
surges are the result of:
• Direct and indirect lightning strikes
• Power company load switching
• Upstream load switching at other facilities
Extensive damage and expensive repairs can result from these types of disturbances if surge protection is not present.
Features & benefits
The OVR NE12 is a multistage protector with fast acting varistor (MOV) and EMI/RFI noise attenuation lter 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.
General
• NEMA 12 enclosure
• All mode protection (L-L/L-N/L-G/N-G)
• Auxiliary contacts for remote monitoring
• Safety disconnect, fused
• LED power on/fault indicator
• Audible alarm
Applications
The OVR NE12 is suitable for protection for all manner of facilities and operations. It is designed with a NEMA Type 12 enclosure, and
rated as a Type 2 SPD, requiring indoor installation on the load side of the main breaker or fuse.
Here are some examples of operations that would benet from an OVR NE12 enclosed SPD:
• Critical power (hospitals, data centers, etc) • Communications
• Renewable energy • Manufacturing
• Water/wastewater • Commercial
