SB466RG | General Electric Fusible Bus Plug

The SB466RG is a fusible bus plug produced by General Electric (GE) and also associated with ABB. This device is categorized under the Spectra family, specifically as a Type SB fusible bus plug. It is designed for integration into three-phase (3PH) electrical systems with a four-wire (4W) configuration, which includes a ground connection. 

The SB466RG operates with a voltage rating of 600 volts (600V) and a current rating of 600 amperes (600A). The device features an interrupting capacity (AIC) rating of 200 kiloamperes (kA) at 480 volts, providing a high level of fault protection for electrical systems. This high interrupting capacity ensures that the bus plug can safely interrupt significant fault currents, thereby protecting connected equipment and maintaining system integrity. 

This fusible bus plug is compatible with Spectra aluminum and copper busway systems, offering flexibility in various industrial and commercial applications. It is designed to accept Class H and Class R fuses, which are commonly used in industrial electrical systems for overcurrent protection. The inclusion of a ground connection enhances the safety of the installation by providing a path for fault currents to earth, reducing the risk of electric shock and equipment damage.
