Power Relays, Over 2 Amps

8921090000 Application Field and Working Principle

8921090000 type relays are designed to be utilized in systems with AC or DC circuits that require high current over 2A. These relays cut in and cut out the power to ensure sure that the load is managed in an effective and efficient way. They are used for many different types of applications, including motor starting, industrial control, and auxiliary contact operations.

The working principle of 8921090000 relays is based on electromagnetic induction. When the primary current flows through the coil of the relay, it will generate a magnetic flux which is passed through the secondary windings. This causes an induced current to be generated in the secondary winding, which in turn activates the contacts of the relay. When the primary current is cut off, the magnet will lose its magnetism and the spring action of the contacts will disconnect the circuit.

The 8921090000 type relays are available in either single-pole single-throw (SPST) or single-pole double-throw (SPDT) designs. In the SPST version, the relay is designed with only one set of contacts that will either connect or disconnect the load. The SPDT version has two sets of contacts, which allows it to be used for either switching between two circuits or providing a changeover between two different components.

8921090000 relays are also available in a wide selection of sizes and power ratings, allowing them to be used in a variety of applications. The relays are also designed to be used with either AC or DC circuits, and they have a high-current carrying capability that makes them suitable for high-power applications. Additionally, the relays have a maximum operating temperature of up to 105°C.

The 8921090000 type relays are designed to operate in a variety of environmental conditions, meaning that they can be used in a wide range of applications. The relays are rated to operate in temperature ranges from -40°C to +105°C, and they are also designed with a large number of contact forms and contact configurations. They are also available with either hermetically sealed or non-hermetically sealed versions.

8921090000 relays are designed to provide a long and reliable service life. They are built with a robust and reliable construction, meaning that they will not degrade or become unreliable over time, allowing them to maintain a high level of performance throughout their service life. Additionally, the relays are designed to be maintenance free and are highly resistant to vibrations and shocks, making them suitable for use in harsh industrial environments.

8921090000 type relays are used in many different types of systems, including industrial and commercial applications. They can be used for motor control, high-power switching, industrial automation, and auxiliary contact operations, making them ideal for a wide variety of applications. Additionally, they are designed to be highly reliable and are very easy to install and maintain.
