What Is CJX2 Series AC Contactor\uff1f<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

ZHIMINGbrand of\u00a0the\u00a0CJX2 series AC contactor\u00a0is suitable for AC power systems operating at 50Hz or 60Hz, with a rated insulation voltage up to 690V. Under the AC-3 utilization category, it supports a rated operating voltage of up to 380V and a rated operating current of up to 620A.<\/p>\n

<\/p>\n

It is primarily used for remote making and breaking of circuits, as well as for frequent starting and control of AC motors. When combined with a thermal overload relay or electronic protection device, the contactor can be assembled into an electromagnetic starter, providing reliable protection against circuit overloads.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
