A reclosing relay is provided with switch settings and microprocessor control to permit emulation of a variety of different styles of motor-driven reclosing relays in power distribution systems. The reclosing relay is particularly suitable for replacement of General Electric Co. ACR11A, ACR11B and other similar model reclosing relays that are not electrically compatible with one another. Plug-and-play compatibility is provided by a chassis with electrical contacts that are both physically compatible with a variety of relay cases, and by switches that reconfigure the functions of the external terminals for compatibility with these types. The relay has a built-in microcomputer controller that is programmable through a serial port, and that provides for software emulation of the various required electrical functions of the reclosing relay. Because the GE ACR11A, GE ACR11B, and other similar types are no longer being made or supported by their manufacturer, the replacement relay allows a reduction in replacement part inventory. The relay is also well-suited for new applications.
