Power relays are devices commonly used in high voltage and/or current control applications. They are typically used to control the on/off switching of high-power transmissions, such as in an automotive starter motor or in an electric motor control system. The 2987011 is one such device, usually found in heavy duty applications where control of large loads is required.

The 2987011 is a single-pole, double-throw (SPDT) contact disc power relay, rated for applications up to two (2) amperes. It is designed to provide a reliable and efficient means of switching a load circuit, such as a starter motor, from one voltage source to another. The relay includes a coil and a set of contacts that can be opened and closed depending on the electric current in the coil.

The 2987011 relay operates on the principle of electromagnetism. When power is sent to the relay through the coil, it creates an electromagnet inside the relay housing. This in turn attracts the armature towards the inside and closes the contacts. When the electric current stops flowing, the internal spring pulls the armature away from the contacts, causing them to open.

The 2987011 relay is typically used when higher current switching is required, such as in automotive starting motor systems, which require large amounts of current. Other applications include welding systems, elevator control systems, motor starter systems, and emergency-stop systems. The relay can also be used for general purpose power switching when high-current levels and reliability are required. The 2987011 is designed to handle high levels of current, yet still remain relatively inexpensive and easy to install.

The 2987011 is a reliable and efficient means to switch a load circuit from one voltage source to another. Its SPDT contact disc design allows the user to control current up to two (2) amperes, making it suitable for both low and high current applications. The easy-to-install design also makes the 2987011 an ideal choice for applications requiring high-power and reliable switching.
