The Klockner Moeller ZE-4.0 is specifically designed for direct mounting on DIL 00M, DIL 0M, and DIL M contactors (e.g., DILM7, DILM9, DILM12, DILM15). How do I correctly set the current on this overload relay? The current should be set to the motor’s Full Load Ampere (FLA) rating listed on its nameplate. The trip rating is 125% of the dial setting, so setting it to the FLA ensures proper protection. What is the difference between the ‘A’ (Auto) and ‘H’ (Hand/Manual) reset modes? In ‘H’ (Hand/Manual) mode, the blue reset button must be pressed manually to reset the relay after a trip. In ‘A’ (Auto) mode, the relay will attempt to reset automatically after it has cooled down. Manual reset is recommended for most applications to ensure a safety check before restarting the motor.
