Power relays are electronic switching devices that help control power supplies within certain electrical appliances and systems. The 8-1393139-5 power relay falls in the category of relays with a current rating greater than 2 amps. It is used primarily in applications where it is necessary to make or break an electric circuit, while protecting other electrical components from current overload.

The 8-1393139-5 power relay consists of a coil, an armature, an insulator, and contacts. The coil consists of a pair of low-voltage, high-ampere-turns windings around a ferromagnetic core. When voltage is applied across the coil terminals, current flows and a magnetic field is created around the core. The armature, which contains a permanent magnet, is also made of ferromagnetic material and is positioned in the magnetic field close to the armature’s poles. There is an insulator between the armature and the coil to insulate them from each other.

When the relay is energized, the magnetic field generated by the coil attracts the armature, and the contact arm is moved by the armature. The contact arm has one or two contacts, which make and break the power circuit. The contacts are designed to operate reliably at the specific current rating of the relay. When the armature is dispelled, the contacts return to the non-energized state.

The 8-1393139-5 power relay is used extensively in industrial and commercial applications, such as heating, ventilation, air conditioning, refrigeration, and building automation. It is also used in household appliances, such as washing machines, dryers, clothes irons, and dishwashers. These relays are ideal for applications requiring heavy-duty switching capabilities, as they can handle large current loads with a high degree of reliability.

The 8-1393139-5 power relay should be selected based on its current rating, voltage rating, contact configuration, and package size. The current rating is determined by the amount of current the relay can pass without becoming damaged or deformed. Voltage rating specifies the maximum voltage the relay can safely handle without being damaged or deformed. Contact configuration indicates the number and type of contacts that the relay can make or break. The package size should be determined based on the amount of space available in the application for mounting the relay.

The 8-1393139-5 power relay is designed to provide reliable switching for heavy-duty applications with currents up to 2 amps or more. Its reliable contact mechanism and durable construction make it an ideal choice for many power switching applications.
