Product Description:

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


Normal working and installation conditions

1. Altitude no more than 2000m.
2. Ambient temperature within-5℃~+40℃ .and the average temperature no more than +35℃ in 24hours.
3. Relative humidity no more than 50% at +20℃, and doesn抰 exceed 90% average of month .
4. No fire, explosion, corrosion and serious shake on the site.
5. Class of pollution: Class 3.
6. The inclined angle between the mounting surface and vertical surface no more than 15o
Note: when usage site is beyond the range of above, please show it when ordering, we will try our best to meet your requirement.


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.

Q:Power steering pump fuse?
Ask someone to turn the steering wheel while you listen at the steering pump. If you can hear the pump make a whine and loud noise, the belt might be slipping. Adjust the belt if necessary. Also, lack of steering fluid may cause the noise. Add fluid if necessary, then turn the steering wheel completely to the left and right several times to purge air from the system. i Inspect the steering pump, connecting hoses and lines around the steering assembly and look for possible leaks using a flashlight if necessary. If you frequently add fluid to the steering pump, the steering mechanism might have a leak. Clean steering components with a shop rag and recheck a couple of days later. You might find a loose hose clamp, torn hose, broken line or crack on the steering pump.
Q:what is wrong with my power windows?
Here are the components to check: The fuse, the window switch, the window motor and the regulator. The regulator is a cable mechanism that actually moves the window up or down (not the same as the motor). If it does not move at all, the fuse, switch and motor are the things to check first.
Q:Is there a way to check and see if a circuit board is still working with a volt meter?
About the best that you can do is to test for power to the board. If you have the input voltage and aren't getting the output, then most likely the board is messed up or a fuse has blown. You may need to call in an electrician and have them look at it. good luck.
Q:how do i check the electrical system on a 1997 KX 60 dirt bike to determine which component is keeping it from?
Assuming the chain and sprockets are in stable condition, approximately halfway between the front and rear sprocket the backside portion of the chain ought to circulate vertically between 25-40mm while status immediately without-one sitting on the bike, no rely if it is greater beneficial than that it may be adjusted till the slack is actual. If there is important lateral stream or the adjusters are on the minimize or any tooth are broken on the sprockets the two the sprockets and the chain must be replaced. The marks on the eccentric adjusters are publications in elementary terms and should no longer be depended on as completely precise. to make optimistic the two the wheels are in an analogous direction use 2 parallel planks the two area of the bike.
Q:NEED Help with this one lads and ladies please, jump leads connected wrong on my car! 10 points given to best!?
If the owner's manual is with it, check the diagram for the fuse box. It should tell you if there is more than one fuse box in the car. Open the fuse box and start checking fuses, The ones that protect the alternator and other major components are usually the biggest. You should check all of them by pulling each out, and looking for a melted piece in the fuse. Try to jump start the car again with the leads attached properly. see if it starts and if everything works, if it does you're golden. If it doesn't, check for fusible links, these are pieces of wire that are designed to melt under high amperage. They are usually a different color than the wire they are attached to and the insulation will look blistered if it has fused. You probably need a new battery anyway, since it stood for two months, with any luck the only thing he fried would be the alternator or voltage regulator. Good luck
Q:2005 lincoln navigator doesent work?
could be wrong but believe the anti theft on the radio needs to be reset
Q:Can a blown fuse cause my car to stop running if so which one?
you have an elecrical short stop changing fuses and locate short formerly you expend the vehicle or fry the computing device. Which fuse is blowing provides someplace to commence finding. it particularly is greater valuable hint than maximum electric powered problems provide you beginning out.
Q:I have a component cable with an end for a ps3, xbox 360 and wii. If I plug a xbox 360 and ps3 into it?
I wouldn't try it - you won't blow up the whole block or even your whole house (worst that would happen to the house is a blown fuse or circuit breaker), but you could ruin either the PS3 or the Xbox 360 or both. I doubt it would hurt the TV, but I wouldn't try it anyway - why risk it? There's no reason to leave them all plugged in and turned on anyway - it surely wouldn't work, as the TV would not know which set of signals to display - the mix would be impossible for the TV to display even if no damage were done. Certainly don't power both units on at once, and I'd even keep only one device plugged in at a time just to be safe in case I forgot and did power up both devices at once just to be safe.
Q:Need help in recognizing power pole types and its components.?
Most of these are insulators. A, D, E G are pin or post insulators B, C F are suspension insulators. The items circled in magenta on F and in yellow on G are fused disconnect switches.
Q:Lincoln town car air suspension?
compressor has a 30amp fuse, but, if the compressor runs, no fuse to check, probably have leaking air springs in rear
