Allen-Bradley 193-T1AB13 Thermal Overload Relay

Allen-Bradley 193-T1AB13 Thermal Overload Relay is a bimetallic overload protection device in the 193-T1 MCS family, designed to protect motors in IEC-style starter circuits by opening the circuit when running current exceeds the set value. It provides an adjustable setting from 0.90 to 1.30 A, enabling precise matching to a motor’s operating current, and it includes one normally open and one normally closed auxiliary contact for signaling or interlocking within the control circuit. The relay is rated for use up to 690 VAC and is intended for use with Allen-Bradley Bulletin 100-C IEC contactors, enabling integrated overload protection within a compact motor starter assembly. With its 1 NO/1 NC configuration and the specified current range, the 193-T1AB13 is a common choice for protecting smaller industrial motors in 50/60 Hz power systems, allowing safe shutdown under overload conditions while maintaining straightforward control logic for alarms or interlocks.
