Product Description:

The Allen-Bradley 193-EEFD is a solid-state overload relay from the Bulletin 193-ED E1 Plus series.³ This device provides comprehensive overload protection for three-phase AC motors. It features a wide adjustable current range of 9 to 45 Amps and offers multiple selectable trip classes (10, 15, 20, and 30), providing flexibility for various motor starting and running characteristics.⁴ It also offers both auto and manual reset options and uses screw-type terminals for connections.⁵ It is designed for use with appropriate Allen-Bradley contactors (consult documentation for specific compatibility) and has a maximum voltage rating of 600V AC.

Key Features:

• Solid-State Technology: Provides accurate and reliable overload protection with a longer lifespan compared to electromechanical overloads.
• Wide Adjustable Current Range (9-45A): Offers greater flexibility in protecting a wider range of motor sizes.⁶
• Multiple Selectable Trip Classes (10, 15, 20, 30): Allows for fine-tuning the overload protection to match the specific motor and application requirements. Different trip classes provide different tripping times under overload conditions.⁷
• Auto/Manual-Auto Reset: Offers the option for automatic reset after a trip (after a cool-down period) or manual reset, or manual with auto reset after a longer time.⁸
• Screw-Type Terminals: Provides secure and reliable wiring connections.⁹
• 600V AC Maximum: Suitable for applications with up to 600V AC supply voltage.¹⁰
