Overview
The Allen-Bradley 193-EA1DB is a solid-state electronic overload relay designed to protect motors from thermal overload conditions. Built to Class 10 standards, this relay delivers rapid, accurate trip response for motors operating at 1–2.9 amperes. Part of the Bulletin 193 family, the 193-EA1DB features manual reset capability and is rated for use with NEMA Size 00 and 100-M05/100-C23 contactors, making it ideal for small to medium industrial motor circuits.
Key Features
- Solid-State Electronic Protection: Electronic motor protection with solid-state design
- Adjustable Current Range: Current rating of 1.0–2.9 amperes with Class 10 trip characteristics for precise overload detection
- Manual Reset Design: Manual reset allows operator control over relay restart after a trip event
- Compact Form Factor: Low-profile design integrates directly onto compatible contactors without requiring external mounting hardware
- Industrial-Grade Reliability: Solid-state construction eliminates moving parts, extending service life and reducing false trips in demanding applications
