Faqs:
  • What is the primary function of the MG4D-BF contactor?
    The MG4D-BF contactor controls the elevator's traction machine by connecting or disconnecting its power circuit, ensuring precise start and stop operations.
  • How does the star-sealing protection function work?
    During emergency stops or power loss, the contactor connects the motor's three-phase windings to form a closed circuit, generating braking force for smooth deceleration and stopping.
  • Why is the silent design important for elevator contactors?
    The silent design minimizes electromagnetic and arcing noise during operation, enhancing passenger comfort and meeting high quiet operation standards.
  • What voltage options are available for the MG4D-BF contactor?
    The contactor supports AC110V, AC220V, and DC110V, making it adaptable to various elevator control systems.
