Overview
The Allen-Bradley 592-EEDC is a solid-state overload relay from the Bulletin 592 E1 Plus family, designed for motor overload protection in industrial automation. This relay operates at a nominal NEMA voltage of 600 Volts with a rated current range of 0.1 to 800 Amps, and provides full load current protection from 3.2 to 16 Amps with 1 Normally Open and 1 Normally Closed contact. It mounts to NEMA size 0 to 2 Bulletin 500 contactors, making it a drop-in solution for existing motor starter installations.
Key Features
- Selectable trip class (10, 15, 20, or 30) with auto-manual or manual reset options
- Trip-free mechanism provides overload protection even when the reset button is pressed
- Adjustment range of 5:1 with 3-second phase loss detection
- Current measurement-based protection with thermal memory and enhanced phase loss protection
- Optical indicator for visible trip indication
- Rugged construction with integrated current transformers and molded power connections
