The ABB OVR series surge suppressor unit is a protective device to ensure that electrical equipment is not damaged by a sudden voltage spike. It has an electrical rating of 5V and 10kA. It is a combined category D, C, B tested protector suitable to protect twisted pair Ethernet networks, including Power over Ethernet (PoE) with RJ45 connections. For use at boundaries up to LPZ 0 to protect against flashover (typically the service entrance location) through to LPZ 3 to protect sensitive electronic equipment.

• Low capacitance circuitry prevents the start-up signal degradation associated with other types of network protector
• Low in-line resistance minimizes unnecessary reductions in signal strength to maximize signalling distance
• Operating temperature ranges between -40°C and 80°C
• Panel mount device
• Sturdy ABS housing with convenient holes for flat mounting or vertically via TS35 'Top Hat' DIN rail
• Substantial earth connection to enable effective earthing
• Suitable for systems signalling on up to eight wires of either shielded or unshielded twisted pair cable
• Very low let-through voltage between all lines
• Will protect all PoE powering modes A and B
