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: changed battery, changed alternator, about a month later, same problem,, the battery is a maintence free sealed one, the alternator new, what else could it be,, it smells like sulfur again: well the first question would be what kind of car is it.next thing is the alternator a NEW one or RE MANUFACTURED one. if you are over charging this usually means the voltage regulator is on th fritz this is sometimes common in a remanufactured alternator if you have an internal one and if you have a external one you can purchase a new one but i would need to know if it has an internal or or External regulator

Q: I recently took the compressor apart, lubricated all components, but the pump still wont work. I hear the relay click when i turn on the air pump uld it be the relay, or the fuse, and if its the fuse, where is it located? i know the relay is in the trunkany help would be appreciated, thank you: There are 2 relays in this system one is located in the right rear of the trunk. The 2nd is located in the r/h instrument panel fuse block and is labeled ( elc relay position e) there are 2 fuses for this system both in above mentioned fuse block ( elc fuse 30a) and (abs/ccr 10a) . Check the elc fuse first . If ok remove the (elc relay position e ) with a fused jumper wire jumper the red wire to the green wire or terminal 30 to 87 and verify pump operation. The terminal numbers are labeled on the bottom side of the relay. I'm assuming the relay you are hearing is in the trunk so it's most likely if that relay is clicking it's working. If the pump operates check for voltage at terminal (85) of the fuse block (ignition on) then check for ground at terminal (86) at the fuse block while the inflator switch is on . If all ok replace relay . If your missing power or ground to any of the above mention terminals locate and repair source of open/short. Most likely the elc relay position e is faulty.Hope that helps

Q: i have determined there is no spark on my sons dirt bike and i have already eliminated the kill button but need to know how to check the coil,stater and CDI box to determine which one has failed.i dont want to go purchase all 3 if i can check these with a simple volt meter or test light.I know the basics of how the system works and know for sure the issue is not with the spark plug or a broken wire since i have traced down all wiring to maks sure it wasent that simple of a fix.: 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: I found a 2x12 Line Six Spider III amp for sale, the vendor claims that it can be fixed by installing fuses. Does this mean that the current fuses are blown, or that it never came with fuses? In the former case, how would I be able to tell if the fuses are blown, or if it only needs new fuses and there's not some other underlying issue?: Ripley, the Line 6 tube amplifiers can have both externally-accessible and internal fuses. A fuse can blow from a voltage spike, or from malfunctioning internal components; it is there to protect circuitry from further damage. Merely replacing a fuse without understanding the underlying causes for failure is just a temporary solution, which at best may only delay the need for further repairs or replacements. If you are really interested in the amplifier, see if the seller will let you take it to a dealer for evaluation. For a modest cost, you will get the complete answer, and maybe save yourself some heartache. Best regards, Dana

Q: Causes 3 amps of current to flow to your stereo? Why is this a good thing?: If there is a 3 amp surge the fuse would melt, instantly stopping the current before your stereo is damaged.

Q: i recently got my battery replaced because it wasnt holding charge. when it came out of the shop, the clock, power mirrors, and floodlights arent running. everything else seems fine, and i checked the fuses, all are intact. There were no problems with those 3 components before the battery was replaced. Any Ideas to fix this? thanks: Did you check the fuse block in the engine compartment. There may be a fuse or relay there that is bad. There may be a spare relay in the box. If this fails, I would go back to the shop and explain it to them. They may have disconnected something and didn't get it hooked back up. Hope this helps and good luck

Q: I am unable to locate the fuse that feeds the components mounted on the rear hatch (including the wiper, door lock, and keyless entry receiver). The service manual has no designated fuse. I would appreciate any help in solving this issue. Thanks.: in side of fuse cover should show full lay out of same look on inside of cover plate

Q: I have a house for sale that has a window unit in the living room. The air has been running fine all summer until just the past few days. As soon as the fuse is changed, the air will run maybe 30-60 sec and then will blow the fuse. We recently had the house treated for mold and not sure if the moisture could have anything to do with it??: you have a short somewhere in the wiring. You should not run it again until you locate the short, because it can cause a fire, and/or ruin other expensive components.

Q: I hooked up a tachometer on my bike and I accedentaly grounded a live wire and nothing would turn on. (headlight, guages, ignition and the bike is basically dead. I found a fuse under a component that is wired directly from the battery that was blown. I replaced it and it turned on my fuse box (Thats what my tach is wired to) is there another fuse I don't know about?: I'm thining you still have a bare wire grounding out somewhere, hard to find to :(

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.: the speaker wires may be corroded,too long,or shorted when pos neg are inserted into speaker wire clips,the net needs to allow a refined search so one can find the device itself,maybe the patent prohibits repair people from showing pics schematics,can you post/upload a pic of the thing? one of front,rear,speakers,and aux components?
