ABB Surge Suppressor Unit

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 7.79V and 20kA. It is a combined category D, C, B tested protector suitable for twisted pair signalling applications, which require either a lower in-line resistance, increased current and/or higher bandwidth. Also, suitable for DC power applications less than 0.75Amps. 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.

Features and Benefits

• DIN rail mount
• High (750mA) maximum running current
• High bandwidth enables higher frequency (high traffic or bit rate) data communication
• Operating temperature ranges between -40°C and 80°C
• Repeated protection in lightning intense environments
• Screen terminal enables easy connection of cable screen to earth
• Strong, flame retardant, polycarbonate housing
• To protect systems against transient overvoltages or surges from lightning and electrical switching events
