Overview
The Allen-Bradley 193-EA1GB is a Bulletin 193-EA solid-state overload relay engineered for reliable motor protection in industrial control systems. This Class 10 overload relay provides adjustable overload detection and manual reset operation, making it suitable for motor starters using Bulletin 100-C09 through 100-C23 contactors in NEMA Size 00 applications.
Key Features
- Solid-state construction (SMP-1 platform) for enhanced reliability and fast response
- Adjustable current range: 12–32A for flexible motor application sizing
- Class 10 trip curve for standard AC induction motor protection
- Manual reset operation ensures controlled restart after overload events
- Integrated auxiliary contacts (normally open and normally closed) for motor status signaling
- Compact design for easy installation in existing motor control enclosures
