1,Rated Voltage and Current: Determine the voltage and current levels that the contactor can
handle, which are crucial for matching the power supply and load
requirements.
2,Contact Material and Configuration: Affect the conductivity, durability, and contact resistance, thus
influencing the performance and service life of the contactor.
3,Coil Characteristics: Such as coil voltage, resistance, and inductance, which determine
the power consumption and operating characteristics of the coil.
4,Making and Breaking Capacity: Indicate the maximum current that the contactor can safely close
and interrupt, respectively, reflecting its ability to handle
electrical loads.
5,Operating Frequency: Represents the number of times the contactor can operate per unit
time, affecting its application in different working conditions.
6,Enclosure and Protection Class: Protect the internal components of the contactor from external
environmental factors, ensuring its reliable operation in different
environments.
