Allen-Bradley 193-1EFDB Thermal Overload Relay

Allen-Bradley 193-1EFDB is a 3-pole E100 electronic overload relay that provides adjustable overload protection for three-phase motors. It is designed to mount directly to 100-C09 through 100-C23 series contactors, consolidating motor protection into a compact, single-unit package for Allen-Bradley control panels. The relay offers an adjustable current range of 3.2 to 16 A, enabling precise protection for motors within that range, and supports either manual reset or automatic reset modes to suit local operating practices. As part of the E100 family, the 193-1EFDB is a solid-state overload relay that interrupts motor current in overload conditions to help prevent damage and downtime.
