1.Products Application
CJX-3 series AC Contactor is suitable for using in the circuits up to the rated voltage 660V.
AC 50Hz or 60Hz, rated current up to 95A, for making, breaking, frequently starting & machine interlocking device etc, it becomes the delay contactor, mechanical interlocking contactor, star-delta starter. With the thermal relay, it is combined into the electromagnetic starter. The Contactor is produced according to IEC60947-4, GB14048.4
1).The product is mainly used in circuit with AC 50Hz or 60Hz, voltage up to 690V, current up to 95A for remotely making and breaking circuit, and also for frequently starting and controlling AC motor.
2).The product adopts direct operated construct to improve electrical lifetime and maintain easily.
3).The product is combined with the auxiliary contact block,time delay block,thermal overload relay to form the delay contactor,
the electromagnetic stater etc.
4).Highly standard modular design is to reduce variety of parts and improve its reliability.
5).The feature is compact constructure ,steady running and longer lifetime.
6). The main components(expect those easily disable parts) can last as long as up to more than 30,000 hours.
7).Products and all key components are finished by precisely machining and accurately assembling and finally testing ,therefore high quality is reached.
