The Legrand LEG412501 contactor features a control switch for selecting operation modes:
- 'AUTO' Position: In this position, the contactor operates automatically based on the control signal applied to terminals A1 and A2. When the control coil is energized, the main contacts close, allowing power to flow to the load. When the control coil is de-energized, the contacts open.
- Anulació manual: The contactor includes a manual override function. If the switch is moved to the 'I' (ON) position, the contacts will close manually. If the switch is moved to the 'O' (OFF) position, the contacts will open manually. The device is designed for manual operation with an automatic reset, meaning it will return to the 'AUTO' position when the manual override is released or when the control signal dictates.
The contactor is designed to accept transitions from cam power supply up to 25A, indicating its suitability for various control applications.
