Overview
The Allen-Bradley 592-EEEC is a solid state overload relay designed for motor protection in industrial applications. This E1 Plus series relay is rated for NEMA Size 0-2 contactors and handles full load currents of 5.4 to 27 amps. It delivers precise thermal protection against overcurrent conditions and is an established component in motor control circuits across manufacturing and facilities maintenance.
Key Features
- Solid state thermal protection—fast, reliable response to overload conditions
- Selectable manual or automatic/manual reset modes for flexible operational control
- Adjustable trip class settings (10, 15, 20, 30) to match motor and load requirements
- One normally open and one normally closed contact for integrated control logic
- Direct mount to NEMA Size 0-2 Bulletin 500 contactors
- Phase loss detection for enhanced motor system reliability
