Allen-Bradley 810-A23A Inverse Time Current Relay

Allen-Bradley 810-A23A Inverse Time Current Relay is a Bulletin 810 device that provides inverse-time current protection for electrical circuits and motors. The 810-A23A carries a coil current rating of 185 A, indicating the current level used to energize the relay coil during protection events. The 810 family supports AC and DC calibrations and is rated for up to 600 V maximum, with catalog suffix A23A representing its specific timing configuration within the 810-5.0 documentation. Used in industrial control panels for motor protection and feeder protection, the inverse-time characteristic allows longer trips at lower overloads and progressively faster trips as current increases, coordinating with other protective devices to reduce nuisance outages.
