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 Ultra-slim product of 7 mm width Very low let-through voltage between all lines - Full mode protection
Applications
High-speed digital communication equipment Process control Systems with long signal lines
