Product Features:

DZ47LE earth leakage circuit breaker is used for the protection against electrical leakage in the circuit of 50Hz or 60Hz, rated voltage single-phase 240V, 3-phase 415V, rated current up to 60A When somebody gets an electirc shock or the residual current of the circuit exceeds the fixe value, the ELCB can cut off the power within the time of 0.1s automatically protecting the personal safety and preventing the equipment from the fault resulted from the residual current.
With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switchover of the circuit under normal conditions. It conforms to IEC61009 standard.

Q: can somebody please explain the parts marked in red on the following image: The item on the left is a fuse rated at 200mA. The 47k items are 47 k ohm (47000 ohm) resistors. I have no idea what the circuit does, but at the 4 pin connector on the right, provides voltages of, from the bottom pin up, 0, 2.5 volts, 2.5 volts, and 5 volts. .

Q: i have a cb base on my home i was connectin the cb on my power supply and i put the wired rong i switch the way is supost to go and know the power swich goes on the cb wont go on i check fuse on power supply its good and radio is good in the fron of the power supply i have 2 button for positive and negative i think the problem is there fuse never burnplease help my question thank you god bless you: Does the power cord coming from the cb radio have a fuse? if so, it is probably blown. If it does not, then you may have fried a diod or other component on the cb radio circuit board.

Q: I need the wiring diagram for a 1999 Saab 9-5 SE. It is for the front fog lights, I have looked everywhere and cannot find a site that has them for free.: generally there is a light(s) a switch, a fuse, and a relay for the components. If you are looking for the schematic, they are the same components for every car so I would recommend going to your local auto parts store, look on the shelf of fog lights, and on the back of the box has the schematic drawn out. you can copy it or just draw them on a piece of paper, because there are not a lot of wires. I hope this helps ~Joe

Q: Blown Kenwood KDC-P5028 CD Reciever?I have a Kenwood KDC-MP5028 CD player. I was installing the system and everything was going fine. The wiring harness has the yellow cable missing which I think the the 12v. I attatched a wire and hooked it all up and everything was working fine. When I pushed the unit into the dash the wire cameout and it touched the black ground wire. I heard a pop and noticed that the unit was smoking a little bit. Now my unit will not power back on. The fuse is still good so thats not the problem. The radio fuse is also intact. Does anyone know what the problem is? Is there an internal fuse I dont know about? Your help wil be much appreciated. Im also trying to avoid taking it to a repair shop because I know they are going to charge me an arm and a leg. Thanks, Johnnie: If the fuses are good and it was a dead short you most likely fried the circut board. If you are mechanically and electronically inclined dis assemble the unit and go over everything with a good magnifying glass. Start at the point of the burn. (it will be obviously marked) and follow the track. If it is only the wire its self then you get off easy by replacing it. Next look inside as many units have another fuse hidden inside. If that is not it and it is one of the fine strips in the board take a very fine bit of wire and solder it in to bridge the burnt section. If any of the small components (resistors, diodes) you can replace the larger ones but not the tiny ones. Damaged ones of any type will be discolored and you can spot them with the glass.

Q: 1. What are the most common electronic components I would need to understand to be able to develop circuits and invent innovative electronic products? I know theres a resistor, capacitor, transformer etc.2. What are the functions of each one of them?: Go to Radio Shcak and buy one of the simple electronics project kits. You'll learn all you need to get started.

Q: i did something really stupid and connected my car battery the opposite way it should be (positive clamp to negative terminal and negative clamp to positive terminal; a few sparks flew). i tried to start the car but nothing happened when i realized what i did wrong i put the battery in the right way and the car started fine. i heard that when you connect the battery the wrong way it reverses polarity or something like that and that the battery cannot be used and that it messes up the alternator too.so that raises a couple question1) do i need a new alternator?2) even though the battery starts the car is it no good?3) will the battery end up exploding or malfunctioning because of the reversed polarity?: the polarity CAN switch and cause problems, but if your car started and runs fine and is charging you probably got by with it. the battery itself should have no lasting problems, there is the possibility that you hurt some electronic components, but this would most likely show up right awayyou probably got lucky.

Q: I recently lost my internal lights, clock and annoying whine that tells me I left the lights on. I worked out where the fuse was after like, an hour of searching the internet forums and found the fuse that deals with the internal lights and clock. Low and behold, it was blown, replaced it with the spare 7.5 rated fuse, checked it, lights came on and clock, and then after about a minute, the fuse blew again. Any ideas what the prob could be? Plus, I couldnt find the fuse for the annoying whine that lets me know the lights are on. Neither could I find any fuse box layouts on the internet, anyone able to help me out?: You most likely have a short that is causing the fuses to blow. First you need to find out if the short is in the wiring for this fuse or wiring from this fuse and another. To do this remove half the fuses prior to replacing the blown fuse. If it still blows then all the fuses are eliminated. Now remove the other half and if it still blows then the problem is within the wiring for just that one fuse. Next unplug the items connected to that fuse and then replace the fuse. If it still blows you have a wiring problem. Either seek help or run new wires. If when you unplug a component connect to the wires for this fuse and the fuse does not blow most likely that part is your problem. Hope this helps But it won't hurt anything

Q: I have an Alpine CDM 7874 head unit in my car the lights have gone dim on 1 side of the faceplate. Is there some fuse I can chage to get them working again, or should I get a new faceplate?: if in case you have a undesirable cconnection or a quick interior the wires. you additionally can want to alter the fuse for the radio/stereo on your vehicle. The fuses are oftentimes placed under the steerage column.

Q: I don't want any theories or speculations. I want a real documented electronic device. Oh and no ancient astronaut theories either.: Diode was the first electronic device.

Q: I have an assignment on 'Electricity in the home'. The part i have to research on is the components of the main eg; main wire, live wire, neutral wire, 3pin plug, fuse, switch.What do these fall under? I cant jus look for main n find these components. I was told its the 'Main Circuit Breaker'. Im lookin for this and non of the components i listed are on the sites. Is there a particular word i have to use. Are there any other components im missing other than the ones listed above?i jus need to write short notes and get some pictures but im not finding any information.: components are: circuit breaker aka MCB circuit breaker box aka distribution panel aka Consumer unit wire of various sizes wire staples outlets switches lights (permanent mounted in ceiling or wall) Parts attached to the appliance, not part of the mains plug wire and the various tools used to put it all together.
