Allen-Bradley 193-BSB60 Overload Relay

Allen-Bradley 193-BSB60 is a Bulletin 193 hand-reset overload relay used to protect small motors in motor-control circuits. It trips on overcurrent within a 4.0–6.0 A full-load current range and is listed as the 7EB60/193-BSB60 combination in the 193 family of overload relays. The device has a cross-reference to MCS-equivalent 193-TAB60, helping match it to related relays in compatible control panels. As a hand-reset overload relay, it requires manual reset after tripping, ensuring the motor remains protected without automatic restart. Manufactured by Allen-Bradley (Rockwell Automation), this relay is designed for use with Allen-Bradley starters in applications where dedicated, localized motor overload protection is needed for motors drawing 4–6 A at their full-load current. Typical uses include small conveyors, pumps, and fans in industrial equipment where motor protection inline with a contactor is required. The 193-BSB60 is part of the broader 193-series family, which provides a range of full-load current options to cover many common small-motor protections.
