The 217-1199-003 application field and working principle is one of the most popular forms of auxiliary relays used in electrical applications. In general, this type of relay is used for two main purposes: controlling the output of electric power from a controlled source, and providing protection for electrical circuits from overloading. In both applications, the 217-1199-003 relay ensures reliable, safe and efficient control and protection of the electrical circuit or system.

The 217-1199-003 is an electromechanical switch-like relay that contains two sets of contacts (either normally open or normally closed) linked to an operating coil and its normally open contact. It is designed to be energized and turned on by an external input voltage or over-current, and the current reverses itself when the external input is removed, thus causing the contacts to revert back to their original state. Generally, the 217-1199-003 is used in situations where a simple switch or circuit breaker cannot provide the necessary operation or protection, such as in alternate current (AC), direct current (DC) or mixed voltage system applications.

The 217-1199-003 application field can range widely depending on the specific application and voltage requirements. Generally, the relay can be used in motor control, circuit protection, electrical energy management, control circuits, transformer protection, motor protection, and other overwhelming protecting duties. Since the 217-1199-003 is a form of an auxiliary relay, it is often utilized in tandem with other safety relays for added safety and protection.

The working principle of the 217-1199-003 is based on the principle of magnetism, whereby the contacts act as a conductor for the electric current for when the coil is energized. When an external input voltage or over-current is applied to the control coil of the 217-1199-003, the exclusive magnetic field generated causes a reverse current flow through the relay contacts, causing them to change position and the two contacts to close. When the input voltage is removed the normal open contacts revert to their original, off position. This action of the 217-1199-003 relay is what enables it to be used for both the control and protection of electric circuits.

The 217-1199-003 is a very efficient and reliable relay, and its simplicity and versatility make it an essential piece in many different applications. Commonly used in industries such as power generation, construction, electronics, and the automotive industry, the 217-1199-003 is an integral part of many electrical systems and is used frequently in industrial applications where safety is of the utmost importance.
