Allen-Bradley 193-BSB60 Overload Relay 4-6 Amp

Allen-Bradley 193-BSB60 Hand Reset Overload Relay (Bulletin 193, Series B) is a three-pole overload protection device designed to safeguard 3-phase motors in control panels when paired with Bulletin 100 contactors. It provides an adjustable full-load current range of 4.0 to 6.0 A, allowing you to dial in the protection level to match the motor’s running current and the circuit’s startup characteristics, while a hand-reset mechanism requires manual restoration after a trip. The unit mounts with no dedicated enclosure or specific mounting hardware, integrating with the contactor assembly to form a compact motor-control package, and its catalog mapping is 7EB60 to 193-BSB60, confirming the same product family and current range. Typical applications include protection of mid-sized 3-phase induction motors in manufacturing lines, pumps, fans, conveyors, and similar equipment where reliable overload protection and a straightforward reset process are important for minimizing downtime and maintaining safe operation.
