What is the formula for thermal to trip a circuit breaker?
Two relevant parameters are current and time. Voltage is irrelevant here. A ballpark number is defined by an (I squared t) rule. IOW, as current (I) increases, it causes time (t) for a trip to decrease exponentially. Exact number is unique for each model fuse or breaker. But and for example, a 20 amp breaker may conduct up to 25 amps for anywhere from many minutes up to two hours before it trips. And yet trip quite suddenly on a 60 amp current flow. A voltage number defines what voltages a fuse or breaker can interrupt. A voltage too high means a fuse or breaker may continue conducting current. Any voltage below its rating does not affect tripping time.
Will circuit breaker cause voltage drop in outlet?
A breaker is a current activated device. New to these forums so, not sure on the etiquette of improving the answer above. I didn't see a button to provide a second answer. That being said; While the breaker reacts to current and not Voltage, Voltage drop to a motor load will cause that motor to draw more current, which can trip the breaker. The higher current draw will also create more Voltage drop, etc. Your best bet is just to stay within the industry standard of 3% drop for feeders, 5% for branch circuits. If this question doesn't involve motors, then Voltage drop outside tolerance will eventually cause the device to malfunction, depending on the severity of the drop, but won't effect the circuit breaker.
What is a generator breaker?
The generator circuit breaker or gcb is a circuit breaker which is connected with the generator . Whenever there is a fault in the generator the circuit breaker trips and disconnects the generator from operation thus it helps the place from a serious accident etc..
You have an elecwaterheater it blows the20amp in line breaker and the 50 amp main?
For a main breaker to trip under these circumstances the rest of the panel is becoming close to its load rating. When the 20 amps breaker trips the rest of the panel is close to or over 30 amps, the 20 amp breaker takes it over the top. What trips a HWT breaker is usually a faulty heating element. It could be the top one or the bottom one.
What could be the problem if a breaker trips when the light is turned off?
A short circuit in the wiring or in the switch.
Does the power supplied to trip shunt trip breaker have to be applied momentarily or can it latch?
A shunt-trip breaker trips when voltage is applied to the coil. It does not self-reset when the voltage is removed, the breaker must be reset manually. The trip voltage can either latch or be applied momentarily, but must be de-energized before the breaker will reset.
Where do you connect the two leads of a shunt trip breaker?
Usually the breaker's shunt trip coil is tied to a corresponding current transformer that is sized to the amperage that is allowed to be passed through the breaker. These types of breakers can also be connected into a distribution monitoring device. If the monitor detects a phase reversal or phase loss or voltage rise or drop the breakers shunt trip coil is remotely energized and isolates equipment down stream from the fault. Shunt trip coil circuits are also used as safety circuits where the situation calls for only one breaker to be energized at a time. If the second breaker is inadvertently closed, this would allow both breakers to be on, the second breaker's auxiliary contacts that are an internally part of that breaker will close the safety circuit and energize the shunt trip in the first breaker to causing it to open. So as you can see the two wires could be part of many wiring configurations depending on what situation calls for.
What is a shunt-trip breaker?
It works just like a normal circuit breaker with one additional function. A shunt-trip breaker also has a built-in magnetic coil that can be energized externally to trip the breaker. For instance, fire sprinklers are sometimes required in the top of elevator shafts in case of a fire in the shaft. If the sprinklers were to spray water on the electric controls in the elevator cab, people could be hurt or killed, either from electrocution or from the elevator malfunctioning. In these cases, a shunt-trip breaker is installed in the circuit feeding the elevator controls, and the fire alarm system sends a trip signal if it detects waterflow from the sprinkler system. This trips the breaker and removes power from the elevator cab. Once tripped, shunt-trip breakers require a person to manually reset them.
Can you use the ansul system contacts in a kitchen to break the cooking circuits with the shunt trip breaker?
Yes, you can. If your shunt trip is 120 volts, just get 120 volt from your panel and take it to your ansul normally open contacts than to your shunt trip braker. than when your ansul system trips it will trip your shunt braker.
How do you detect if a shunt trip breaker is malfunctioning?
The way to detect if a shunt trip breaker is malfunctioning is to manually trip the breaker. The shunt is usually wired through a auxiliary relay. Make sure that before you trip the breaker that the load can be shut off without taking a production line etc. off line. Trip the auxiliary relay using a test jumper to activate the relays coil. The breaker's handle will move to mid throw and the load will disconnect from the supply power. If the breaker trips then it is working properly. If the breaker does not trip trouble shoot the circuitry that is used to trip the breaker. Usual problem is an open circuit.
What is shunt coil?
A shunt-trip coil is a built-in component of a shunt-trip circuit breaker. It is a magnetic coil that can be energized externally to make the breaker trip to shut off the flow of current. For instance, fire sprinklers are sometimes required in the top of elevator shafts in case of a fire in the shaft. If the sprinklers were to spray water on the electric controls in the elevator cab, people could be hurt or killed, either from electrocution or from the elevator malfunctioning. In these cases, a shunt-trip breaker is installed in the circuit feeding the elevator controls, and the fire alarm system sends a trip signal if it detects waterflow from the sprinkler system. This trips the breaker and removes power from the elevator cab. Once tripped, a shunt-trip breaker requires a person to reset it manually.
What is tripping relay?
You need to remove everything connected to the breaker and see if it still trips. If it does it is in the wiring or possibly a bad breaker. Disconnect load from breaker and see if it still trips. If so replace the breaker. If it still trips and is not the breaker then you will have to start pulling each outlet from wall and checking after disconnecting each outlet.
What do you do when your air conditioner trips the breaker when it kicks on?
Try adding a cercuit breaker right on the AC.
What is the name of device to check automatic circuit breakers Its operation is the following you supply voltage with smoothly or uneven increase till breaker trips. thank you?
It is called a rheostat, it is a variable transformer
Is it dangerous to have water in circuit breaker?
Yes. Water can damage the breaker and prevent it from working, or it may continue to carry current after the breaker trips.
What cause the Main Breaker trips when I start a 30KW 3-phase Motor(Star Delt Starter)?
The wiring is like this:[[30KW Motor ---- Star Delt Starter(100A Breaker inside) ----- 200A Breaker------50A Breaker(Inside the breaker box which located inside the factory) -----100A Main Breaker]]Once I try to start the Motor, the Main Breaker trips immediately.
How does Under voltage coil in breaker works?
There is an internal mechanical trigger within the breaker. This trigger requires very little force in order to trip the breaker. / There is also a spring loaded electromagnetic solenoid that is wired to the line side of the breaker, when incoming power is present the solenoid is retracted. / When line power is too low, or absent the spring loaded solenoid releases and strikes the mechanical trigger, this in turn trips the breaker. / Oddly enough, the voltage sensing is generally across only two of three phases on a three phase breaker, so there is the possibility of a single phase condition, if the unmonitored phase is lost. / One reason why Under Voltage breakers are used is to keep machinery from starting automatically when incoming power is restored after a power outage or after a significant drop in line voltage.
