AX Series Motor Contactor (Model AX 185~205A)
Product Introduction
The AX Series Motor Contactor (Model AX 185~205A) is a robust
electrical component designed for reliable motor protection and
control in industrial applications. Engineered to meet IEC 60947
standards, this contactor features 3 NO main contacts and 1 NO/1 NC
auxiliary contact configuration, suitable for main circuits up to
1000V. With a rated operational current of 185A (AC-3, 415V at
55°C), it ensures efficient power switching for motors up to 90kW.
The contactor’s durable design includes a plastic housing, IP40
protection for auxiliary terminals, and mechanical durability of 5
million operations, making it ideal for heavy-duty environments.
