Electrical Single Phase/Three Phase AC Contactor (CJX7)

Product Description

1. Application

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