General Electric CR308BT021AGAAAAA Industrial Control Relay

General Electric CR308BT021AGAAAAA Industrial Control Relay is a GE CR308-series three-pole combination starter used to control and protect motors in industrial electrical panels. As part of GE’s CR300 family, it consolidates a main switching path with overload protection and control wiring in a single enclosure, streamlining wiring and panel layouts for motor control applications. The suffix BT021AGAAAAA encodes the unit’s exact configuration within the CR308 line, with coil voltage, enclosure style, and overload options defined by the variant; precise electrical ratings and terminal arrangements depend on the suffix and should be verified against GE’s official literature for this exact part. A closely related configuration, CR308CT021AGAAAAA, is cataloged as a 3-pole NEMA combination starter with a non-fusible disconnect, illustrating the family’s range of enclosure and disconnect options. Common applications for CR308-series starters include motor starting and protection in industrial equipment such as pumps, fans, conveyors, and other mid-to-large load scenarios, where compact integration of switching, protection, and control is advantageous. This model is designed for panel-mount installation in industrial environments, with accessory compatibility and configuration options typical of GE’s CR300 series, all defined by the specific suffix and accompanying documentation.
