Allen-Bradley 193-EA1DB Motor Protection Overload Relay

Allen-Bradley 193-EA1DB is a solid-state electronic motor protection overload relay designed for use with Allen-Bradley Bulletin 100-M05…100-C23 contactors to protect three-phase motors. It senses motor current in the 1.0–2.9 A full-load range and trips on overload with a Trip Class 10, requiring a manual reset to resume operation. Rated for up to 600 V AC in three-phase circuits, the 193-EA1DB belongs to the 193-EA family of electronic motor protection relays and is the manual-reset variant associated with Series A configurations. It is intended to be mounted with compatible contactors to form a motor starter that provides overload protection by interrupting current during abnormal conditions, and as part of the Bulletin 193-EA/193-ES family this 1.0–2.9 A version is commonly used where electronic protection is preferred over traditional thermal overload relays in industrial motor control panels. When selecting, verify the motor’s full-load current falls within 1.0–2.9 A and confirm compatibility with the 100-M05…100-C23 contactors in your control scheme.
