Parameters: Rated Voltage (Un): 220V AC (standard voltage for single-phase or industrial control systems) Coil Voltage: 220V AC Number of Poles: The contactor is available in different configurations based on the number of poles, typically 2P (2 poles) or 3P (3 poles), depending on the application. Rated Current (Ie): The contactor’s rated current typically varies by model within the MT series. For MT250, the rated current could be up to 250A depending on the exact configuration. Rated Frequency: 50/60Hz (suitable for both 50Hz and 60Hz electrical systems) Mechanical Durability: The MT250 contactor is designed for long service life, with a mechanical durability of up to 10 million operations. Electrical Durability: The contactor can handle up to 1 million electrical operations under rated current and switching conditions. Auxiliary Contacts: Auxiliary contacts may be available to monitor the status of the contactor, indicating whether the contactor is open or closed, which can be useful for automation systems. Protection Features: Can include options for overload protection, coil suppression to protect the switching mechanism, and thermal protection to prevent overheating.
