Allen-Bradley 193-BSB 22B Overload Relay

Allen-Bradley 193-BSB22B hand-reset overload relay with adapter provides thermal protection for small motors in 193-series starter circuits, rated for a 1.5–2.3 A full-load current range, and features a bi-metallic sensing element that trips on overload and requires manual reset after a trip. As part of the 193 Bulletin family, the 22B variant belongs to Series B hand-reset relays and is designed to mount with compatible Allen-Bradley starter assemblies, with the adapter included for installation. This device is suitable for industrial applications such as pumps, conveyors, and fans where reliable overload protection helps prevent motor damage and electrical faults in legacy control systems.
