Square D 1976-BI Starter Overload Relay Reset Unit

Square D 1976-BI is an external reset unit developed for use with Square D Class 9065 overload relays on open-type magnetic starters, specifically in TY ARO-IR starter configurations. It provides a dedicated reset input that allows manual resetting of the overload relay after a trip without disassembly, streamlining service and recovery in panel assemblies. Designed to be compatible with 9065 overload relays and programmable as part of open-type starter systems, the 1976-BI supports installation in enclosures that accommodate external reset mechanisms (including NEMA 1, 4 or 12 environments) when paired with the appropriate reset kit. In practice, this unit is mounted as an integral part of the overload-relay assembly to furnish a reliable remote reset path, making it suitable for industrial motor control duties where quick, hands-on reset capability is required after an overload event. Typical applications include conveyors, pumps, fans, and other motor-driven equipment in process and manufacturing settings that rely on straightforward, field-accessible reset functionality to minimize downtime and maintain continuous operation.
