100-KFA22Z Elevator Auxiliary Contactor KM256333/KM995910

Model No.: 100-KFA22Z 2NO2NC

Part No.:KM256333/KM995910

An elevator auxiliary contactor is an electrical device used in elevator systems to control auxiliary circuits or support functions within the elevator control system. It plays a critical role in ensuring safe and efficient operation, especially in complex elevator systems where multiple components need to work in coordination.

Key Features and Functions:

1. Auxiliary Control:
   • It operates auxiliary circuits that handle tasks like lighting, signaling, or powering secondary systems within the elevator.
2. Interlocking:
   • Auxiliary contactors are often used in safety interlocks, ensuring that the elevator does not operate unless certain conditions are met (e.g., doors are closed).
3. Signal Transmission:
   • They transmit signals between various parts of the elevator control system, ensuring proper synchronization.
4. Load Management:
   • Helps in managing smaller electrical loads that do not require the full capacity of the main contactor.
5. Durability:
   • Designed to withstand frequent operations in high-usage elevator systems.

Applications in Elevator Systems:

• Door control circuits.
• Lighting and fan control in the elevator car.
• Indication or signaling systems (e.g., floor indicator lights).
• Backup power switching circuits.
• Fault monitoring systems.

Maintenance and Troubleshooting:

• Inspection: Regularly check for wear, loose connections, or burnt contacts.
• Cleaning: Clean the contacts to prevent poor conductivity.
• Replacement: Replace the contactor if it exhibits mechanical failure or excessive arcing.
