Overview
The Allen-Bradley 592-EEEC is a Bulletin 592 electronic overload relay from the E1 Plus series, engineered to provide precise motor protection in three-phase industrial applications. Built with solid-state technology, this relay delivers fast, reliable response to overload conditions while protecting machinery from thermal damage. The 592-EEEC mounts directly to NEMA Size 0, 1, and 2 starters and is commonly found in motor control centers and distributed automation systems.
Key Features
- Adjustable Current Range: 5.4–27 Full Load Amps (FLA) for flexible motor sizing
- Selectable Trip Class: Class 10, 15, 20, or 30 for customized motor starting profiles
- Phase Loss Protection: Detects single-phase conditions and trips to prevent motor damage
- Dual Reset Options: Manual or automatic reset modes for different control strategies
- Auxiliary Contacts: 1 normally open (NO) and 1 normally closed (NC) for circuit signaling
- Solid-State Design: Electronic circuitry ensures faster response and greater repeatability than thermal devices
