Power Relays, Over 2 Amps, 8-1393139-2 Application Field and Working Principle

A power relay is an electronic component used to switch an electrical circuit on and off remotely. It is most often a relay switch, though there are other types of relays as well. This particular power relay, 8-1393139-2, is for applications requiring over two amps of current. It is designed for large, complex electrical systems, and can be located in either a panel or another type of enclosure.

The 8-1393139-2 relay is composed of two parts: a coil and contact points. The coil is charged with an electric current and makes an electromagnet that opens or closes the contact points. When the device is activated, electrical current flows through the contact points and controls the circuit. If the current is too high, the contacts can become damaged.

This power relay has a UL certified rating up to 480 volts. It is available in a variety of sizes. It also has a snap-action contact makeup and a durable design for increased performance. It provides an optimum level of protection and is designed for long service life.

This relay also features an envelope seal that helps prevent dust and dirt from accumulating. It also has a cap to protect the contacts from oxidation. The cap can be easily removed for maintenance.

The 8-1393139-2 is designed for use in industrial and consumer applications such as: air conditioning, refrigeration, automated and manual switch control, electromagnetic contactor control, as well as other noise and mechanical protection.

The 8-1393139-2 is a single-pole, double-throw (SPDT) relay. The SPDT relay can be used to switch between two different circuits or to control a circuit in multiple stages. The advantage of this type of relay is that it can handle higher current loads than single pole relays.

When the current flowing through the relay’s coil is high enough, it will trigger the relay to switch, thus completing the electrical circuit. This can be used to can turn on/off a circuit, open/close a switch, or open/close a valve.

The 8-1393139-2 also features an overload and short circuit protection feature. If the current being supplied to the device is too high, it will automatically shut off, protecting the contacts from damage.

To use the 8-1393139-2, it must be connected directly to the circuit and the voltage must match it’s rating. It should also be wired correctly and tested regularly for proper operation.

The 8-1393139-2 is an excellent choice for applications requiring over two amps of current. It is a durable, reliable device with a UL certified rating up to 480 volts. It is designed for long service life and features overload and short circuit protection for increased performance and safety.
