Overview
The Allen-Bradley 193-ED1CB is a solid-state IEC overload relay from the E1 Plus family, designed for motor control and overload protection in industrial automation applications. This 3-phase relay provides adjustable current protection from 1 to 5 Amps and operates at 600-690 VAC, 50/60 Hz. The relay mounts directly to Allen-Bradley contactors (sizes 100-C09 through 100-C23) and features self-powered operation, minimizing heat generation and simplifying installation without external power requirements.
Key Features
- Adjustable 1-5 Amp current range for flexible motor protection
- Class 10 trip protection (responds within 10 seconds at 600% overload)
- 3-phase IEC-compliant design for motor control applications
- Phase loss protection prevents single-phase operation damage
- Manual reset functionality with automatic trip capability
- Self-powered design eliminates external power supply requirements
- Secure screw-type terminals for reliable electrical connections
- Direct mounting to 100-C09 to 100-C23 contactor frame sizes
