Power relays, over 2 Amps, comprise a large group of switching devices designed to operate on low power. Different types of relays are best suited to different tasks, including the KUP-11D55-125. This relay is typically used to switch power from one source to another, without disrupting the circuit. It can also be used to provide protection from electrical surges, as well as to act as a safety feature.

The KUP-11D55-125 is a high-power relay with a voltage rating of 250V AC, and a current rating of 2 Amps. This relay features two main contacts, which are normally closed, and two auxiliary contacts, which are normally open. The two main contacts are connected to a coil, and when energized, the contacts close. This allows the power to flow from one side of the relay to the other. When the coil is de-energized, the contacts open, stopping the power transfer.

The two auxiliary contacts serve two essential functions. First, they can be used to detect an overload condition. When an overload occurs, the current flow will increase enough to cause the auxiliary contacts to close. This triggers a signal to shut off the power, or to energize another, different coil. This can be used to open a breaker switch or to shut down some other system which is being overloaded.

The second purpose of the auxiliary contacts is to provide a path for the power to flow when the relay is de-energized. If the auxiliary contacts are kept closed, then power can still flow from one side of the relay to the other, even when the relay is not actuated. This is a useful feature when you need to provide power to an external device, without having to worry about the reliability of the relay.

In addition to the two main contacts and the two auxiliary contacts, the KUP-11D55-125 also features an LED that can be used to indicate the status of the relay. This LED is normally lit when the relay is energized and off when it is de-energized. This can be used as a safety feature, allowing the user to easily see if the relay is energized or not.

The KUP-11D55-125 is a versatile and useful relay, which can be used in a wide variety of applications. Most commonly, it is used for high-power switching, such as when providing power to an external device. It can also be used to provide protection against electrical overload, as well as to provide an additional layer of safety. By understanding the working principle and application field of the relay, it can be put to good use in a myriad of ways.
