It senses the motor current and trips when the current exceeds a predetermined limit for a specific duration.How do I choose the correct trip class?The trip class determines how quickly the overload relay will trip when an overcurrent condition occurs. Lower trip classes (e.g., Class 10) are used for motors with short starting times, while higher trip classes (e.g., Class 30) are suitable for motors that require longer starting times without nuisance tripping. Consult your motor and application specifications to select the appropriate trip class.Is this relay compatible with other contactor brands?While the 193-1EFFD is specifically designed for seamless integration with Allen-Bradley 100-C30 to 100-C55 contactors, it may be possible to use it with other brands. However, compatibility and performance cannot be guaranteed. It is recommended to use the relay with its intended contactor series for optimal functionality and ease of installation.
