The Allen-Bradley 193-1EEFD E100 Electronic Overload Relay is a motor protection device designed for direct mounting with compatible Allen-Bradley motor starters and contactors. With an adjustable current range of 11 to 55 A, this overload relay provides electronic motor protection for industrial applications requiring reliable overload monitoring.
The 193-1EEFD belongs to the E100 Electronic Overload Relay family, which is widely used in motor control assemblies where compact installation and integrated protection are required. Its direct mounting design allows it to be installed with compatible contactors without requiring additional mounting hardware.
This component is commonly maintained as a spare part in industrial control panels, especially where existing Allen-Bradley motor starter assemblies are still in operation.

Where This Overload Relay Fits
The 193-1EEFD is installed on the load side of motor control assemblies where protection against motor overload conditions is required.
Typical equipment using this type of overload relay includes:
| Equipment Type | Application |
|---|---|
| Pumps | Motor protection |
| Fans and blowers | Overload monitoring |
| Conveyors | Motor circuit protection |
| Machine tools | Starter assembly protection |
| Industrial machinery | Motor maintenance applications |
The direct mounting configuration makes this model suitable for compact motor starter arrangements where panel space is limited.
Direct Mount Configuration
Unlike separate panel-mounted overload devices, the 193-1EEFD is designed to attach directly to compatible contactors within an Allen-Bradley motor starter setup.
This installation style provides:
- Reduced control panel wiring
- Compact motor starter assembly
- Easier replacement of existing starter components
- Consistent integration with Allen-Bradley motor control products
When replacing an existing overload relay, the original starter model and overload configuration should be checked to ensure proper compatibility.
