When a monitored primary current is overloaded to a piece of electrical equipment in an industrial setting, AC current switches are the go-to component to kill the current quickly and avoid problems with system overloads. You can pick up AC current switches just about anywhere, and all of them are created to perform the same functions. However, not every AC current switch performs the same because every unit is built or manufactured by a different company. There are certain features you should be looking for when you buy high-quality AC current switches to connect to your industrial equipment.
Make sure the current switches are self-powered.
AC current switches that pull power from the existing current line are not the best option. Even though it can be a little more cumbersome to have to connect the AC current switches to their own power supplies during installation, the fact that the switch relies on its own power source means you will not lose any power when the switch is inserted. Plus, if you do have to kill the current to the equipment, the switch will actually still function, which is a lot more convenient.
Make sure the current switches have clear indicator lights.
Most modern AC current switches do have some type of indicator light to let you know whether the current is active, inactive, or idle during use. However, the indicator lights should be readily visible and should protrude from the switch slightly so that they are not easily covered with debris and grime. If you have the clear light indicators, it is easier to catch on when the current is lacking so you can make adjustments. LED indicator lights are usually the best because these low-energy lights do not require a lot of energy to stay illuminated.
Make sure the switches offer efficient switching with no leakage.
You can pick up AC current switches pretty cheap, even ones that are designed for large-scale industrial power operations. However, the most inexpensive versions are not always the best. Some of the cheaper relay type current switches can cut the current, but they can also be inefficient at doing so, allowing current leakage. The best designed current switches are digitally operated, so they have a clean disruption to current.
Overall, the more time and attention you pay to getting a good AC current switch, the more efficient and safe overall electrical supplication will be. Reach out to an industrial equipment and supplies company for more information.
