There are several different ways a Shunt Resistor can be used. One of these ways is to turn off the power if there is a short in the circuit. If you have a device which has a very high output current, it can be dangerous to leave it on continuously, as it will draw far more power, and could easily overheat. This means that the device will overheat and break, and if there is no back-up power source, it can also start a fire. Find modern ammeter shunts or see these modern shunts.
Another way that a Shunt Resister can be useful is if there is a fluctuation in the input voltage. If you want to protect your circuit, then you should try and get a device that has circuit protection built into it. These are usually called input Shunts and are usually used for circuits which receive power from mains electricity. If you use one of these, then the circuit protection will cut out if any of the mains power is lost. If the power cuts out completely, then the circuit protection will cut the power to the device, stopping it from being damaged.
Some manufacturers make devices which have a variable resistance value. They are used on circuits which have an adjustable input voltage. When the input voltage changes, so does the output. This is useful if you want to control the amount of power which is input into the circuit, and you want to ensure that it never goes above a certain level. In this way, the device will shut down if the input voltage goes over a certain level.
There are some other types of Shunt Resister which are slightly less common than the ones that just come with circuit protection. These are unitary resisters, which do not require any other device for its output. They are useful for controlling the amount of current that goes through one circuit at a time. If you are looking to control more than one circuit at a time, then you can use one of these. However, they are not as common as the ones which do have circuit protection.
Whatever type of Resister you decide on, you must know how to check for shorts and what to do when one is tripped. There are a number of things which can cause a short, and these include power surges, connecting in excess power, and connecting things in reverse. You should always try and ensure that these things do not happen when you are using a circuit protection device. A good thing to do would be to use a circuit tester to make sure that your Resister device is working properly. If you find that it is not working properly, then it is definitely time to replace it.
