Overview
The Allen-Bradley 193-EEFD is a three-phase electronic overload relay from the E1 Plus series, engineered to deliver precise motor overload protection in industrial automation and control applications. This IEC overload relay is designed for motor protection applications with adjustable current settings from 9 to 45 amps. The unit features DIP switch settings to select the trip class (10, 15, 20 or 30) and the reset mode (manual or automatic), making it highly adaptable to diverse motor-starting characteristics and load profiles.
Key Features
- Supports 9–45 A adjustable current range, suitable for a wide variety of motor sizes, and includes 1 normally open (NO) and 1 normally closed (NC) auxiliary contact for feedback or interlock circuits
- Integrates directly with Allen-Bradley 100-C30 to 100-C43 contactors
- Selectable trip classes (10, 15, 20, 30) for customized motor protection
- Application-specific integrated circuit (ASIC) monitors motor performance continuously
- IEC-compliant design for international motor protection standards
- Phase loss protection built-in
