Reliance Electric 76624-S N.O. Auxiliary Contact

Reliance Electric 76624-S N.O. Auxiliary Contact is a two-contact auxiliary switch block designed for use with Reliance Electric control gear, including legacy Baldor Reliance and ASEA Brown Boveri equipment. As a No. 2 auxiliary contact, it provides two normally open contacts that close when the associated coil energizes, enabling signaling, interlock, or control-logic functions within motor-control circuits. The 76624-S belongs to the Reliance auxiliary-contact family, with several listings noting its role as an auxiliary contact used to expand control logic in relay assemblies; a closely related model, 76624-T, offers two normally closed contacts (2NC) for alternative logic needs. The module is described by suppliers as a compact rectangular block, roughly 4 inches long by 2 inches wide, with a black housing and a white actuator piece that interfaces with the mating relay or starter assembly. Because these are legacy parts, current availability and exact mechanical fit depend on the specific Reliance Baldor drive family being serviced, and many listings treat the 76624-S as surplus or rebuilt stock. In practical use, this auxiliary contact serves to extend control circuits by providing additional, isolated NO contact paths for status signaling and interlock logic in industrial motor-control applications.
