Applicable Range

CKJ5 series AC Vacuum Contactor (hereinafter called contactor) is designed for long-distance making and breaking in circuit, frequency starting and controlling AC motor in the power system with AC 50Hz～60Hz, rated operating voltage to 1140V. It also can be formed with thermal relay and all kinds of protection apparatus, as electromagnetic starter, especially applies to explosion electromagnetic starter and all sorts of power control equipment .It may apply to the department of mine, metallurgy, petroleum, chemical industry, power, communication transportation, shipping, architecture and so on.

Applicable Standards

National Standards: GB/T 14048.1 GB 14048.4 JB/T 7122
National Standards: IEC 60947-4-1

Structure features

Vacuum Contactor is composed of vacuum arc extinguishing system, electromagnetism system, lever transmission system, auxiliary contact, setting gear, isolating framework. The main characteristic as following:
1. Contact should be sealed in the vacuum explosion chamber which is isolated .
2. Contact will not be effected due to outside pollution.
3. Contactor takes vacuum as the dielectric of arc extinguishing with high breaking capacity and long life. For instance the electrical life of
AC-4 with 4 ×10 times even more than 6×10 , which is impossible for other contactors.
4. If the electric arc can not spray outwards, so there is no fire and blast.
5. There is no harmful gas and ensure clean operation environment.
6. Small distance and short over-travel make the full contactor compact and light,meanwhile, it provides quality products for selections of
electric apparatus assembled and assembly equipment.
7. The control circuit is composed of DC magnetism system and setting current gear.
8. There is no noise during operating.
9. AC or DC power supply will be right.

Outline and Installation Dimensions

Q:I have a 2004 Jeep Grand Cherokee. A couple days ago the blower on the ac/heater stopped working (the light on the AC button doesn't come on either, which maybe connected to the blower) and along with that, my turn signals now won't work. The turn signal lights (both on the dash and outside) do work when the hazard button is on though. I've checked every fuse I could find underneath the dash and under the hood. Then yesterday it overheated, which makes me think the radiator fan won't run either, becuase if i keep it about 45mph it stays cool until I stop. Are these components tied together somehow? Is there a shared relay or something?: Fans usually have their own relays my car has two. Completely different systems would not be connected. Look in your owners manual there may be another fuse box. My daughter's car has 4 fuse boxes.

Q:I am trying to install a additional parts to my car. when i remove the bare PCB with lcd from the head unit. i accidentally grounded the circuit board to the Metal plate, it create a little spark. now the LCD doesn't work. my question are1. is the circuit board fried?2. could it be just a blown fuse?3. after ground the board, could it be just burn resistor?: Fried! Sorry.

Q:considering this car for a project btw i'd do ALL the work i mean parts: Drainage' is cheap to fix, once you find it. If it's just your time, (and you've got a lot of it), go ahead. It means isolating parts of the electrical system and patiently going over the wiring to find the 'leak'. (In a vehicle that old there might be a lot of frayed/abraded wire to replace because it's 'about ready to go'.)

Q:I'm currently in the market to purchase my first washer and dryer set for my family of 4. We are looking to spend no more than $1,500 on a complete set. What are your recommendations? Obviously we are looking for longevity in the set. We do between 4-6 loads per week. Thanks for your help!: I have very good and long time performance from Sears Kenmore washer and dryer products!

Q:I was preparing to drive my car at night.as i turn on the lights smoke puff out just beneath the dashboard near the instrument panel.all the lights are ok except my panel which is pitch black.I cant see the speedometer,tachometer etc.Smell of burned plastic fills the cabin atmosphere.The car engines has no problem.: one of the wires short circuited, that is on the parking light circuit. without anything using the power the wire overheated and burnt the plastic coating. Shouldn't be very much to fix since you know what caused it and where it had the smoke.

Q:I asked how to fix it, but was just told the same thing everyone else said, go to a mechanic and let them do it. I would like everyone to know write now that is my car, and I intend on learning everything I can about it, secondly I'm broke, and thirdly, i am a very poor grammarist.lol but seriously I would really like to know what this is.: uuuuhhhhhhhhhhhhhhhhh.what!!!

Q:I have a Sony R2400 stereo system that apparently overheated during hours of continuous use. Now, when I turn it on the only thing that comes on is the red light indicating which playback method is selected (tape, cd, etc.). Does anyone know what component would likely be the damaged one causing this? I am an engineering student, so I am willing to make an attempt at a repair if I can figure out what is wrong. Thanks.: okorder

Q:dose anybody know how to fix the( interior light,power lock ,sunroof ,trunk opener button and radio, which are not working, and they were stoped working at the same time, and i am trying to enter the code for the radio, but one of numbers is zero, and i dont see that on my radio all . please give me your advices if you have any experience about this . thanks: sounds as it those components run of the same fuse check fuses and i bet you will find a bad fuse if so replace the fuse with the same size it it blows again then you have a confirmed there is a short somewheres at which point i recommend taking it to a repair shop to get checked out as for the radio call a VW dealer they probably will be more than willing to tell you how to go about this.

Q:2003 dodge grand caravan the parking lights wont come on and i can find the fuse! i looked at the fuse box in the engine compartment and all the fuses look good! is there another box ? please help. ps my headlights work and so are the dash lights: when you open the door look on the end of the dash on that van, there's a panel that you remove,there you,ll find the main fuse box for the the inside components and the one for the park lights,good luck.

Q:i thght my car was flooded but then i checked the fuses and saw the fuel pump fuse was blown but when i replaced itlt; that one blew rite away!: You need to trace the wire begining at the pump you have a short . a bad pump will not blow the fuse.
