3. Key Features
3.1 High Breaking & Making Capacity
With a breaking capacity of 100 kA and making capacity of 220 A, the contactor can safely interrupt large short-circuit currents and withstand inrush currents during motor startup. The advanced arc-extinguishing chamber rapidly extinguishes arcs generated during switching, preventing contact ablation and ensuring long-term reliable operation.
3.2 Compact Modular Design
Adopting a compact structure, the contactor saves installation space in electrical cabinets, facilitating dense arrangement of low-voltage components. The modular design allows flexible configuration of auxiliary contacts, thermal overload relays, and surge suppressors, adapting to diverse application requirements without additional mounting brackets.
3.3 Long Service Life
Featuring silver alloy contacts with excellent electrical conductivity and wear resistance, the contactor achieves a mechanical life of 10 million operations and electrical life of 1 million operations (AC-3). This long service life reduces the frequency of replacement and maintenance, lowering the total cost of ownership for industrial users.
3.4 Wide Environmental Adaptability
The contactor operates stably in a wide temperature range of -25°C–60°C, adapting to both cold northern industrial workshops and high-temperature southern environments. The IP20 protection class prevents dust intrusion, ensuring reliable performance in dusty scenarios like cement plants and mining equipment control systems.
