Allen-Bradley 810-A23A Inverse Time Relay 600 VAC

Allen‑Bradley 810‑A23A Inverse Time Current Relay is a high‑voltage protection device designed to monitor load current in industrial circuits up to 600 VAC and to trip a connected circuit when an overload is detected. Part of Allen‑Bradley’s Bulletin 810 inverse‑time relays, the 810‑A23A uses current sensing to initiate a timed interruption: the heavier the overload, the shorter the trip time, helping coordinate protection in motor feeders and power circuits. This unit is intended for installation in control panels and motor protection schemes, typically paired with a current transformer to sense actual load current and coordinate with contactors and overload relays. The 810 series is specified for industrial environments and is compatible with standard Allen‑Bradley protective assemblies used in motor protection applications. Typical applications include protection of motors, feeders, and other 600 VAC circuits in manufacturing and process facilities, where reliable inverse‑time protection helps minimize nuisance trips while ensuring prompt disconnection under severe overloads.
