> Application
CJX7-9~300 AC contactor(hereafter refer to as long-distance range making and breaking the
contactor)is mainly used in power system with electric circuit, and combines the electorm
AC 50/60Hz, therated working voltage up to agnetism starter with the suitable thermal over-
660V, under the application category of AC-3, load relay or the electronic protector to protect
when the rated working voltage 380V, the rated against the possible overload electric circuit
operating current to 300A electrical, for the during operation(running).
