Power Relays, Over 2 Amps: 8021-69000 Application Field and Working Principle

The 8021-69000 series is a type of power relay designed for use in application fields such as telecommunications, industrial automation, electricity distribution, HVAC, and power supplies. This type of power relay is designed to be able to switch and regulate high-power circuits up to and over 2 amps. It is usually factory-set and supplied in either normally open or normally closed configuration and can be fitted with a variety of accessories including coils, connections, mounting brackets, and more.The working principle of the 8021-69000 relay is fairly simple. When the relay is first energized or “turned on” by a small amount of current running through its coil, it pulls an armature or movable contact to close the switch. This activates the relay’s electrical circuit and allows current to start flowing. The power needed to hold the circuit closed and keep it active is supplied by either a coil or a Permanent Magnet (PM). A PM keeps the circuit running at a steady rate, and is usually found in relays used in high and medium power applications. When the relay is operating at high power levels, a resistor may be added to control the flow of current and ensure that the circuit does not become overloaded.The 8021-69000 series of relays is particularly useful for applications that have a high level of demand, such as industrial automation systems and electricity distribution. It has a high switching capacity, including up to 20A, and is able to handle up to 5kV peak voltage and 100Hz AC1. The contacts open and close with minimum wear and tear, ensuring that the circuit is not damaged by regular use. The relays also have UL, CIX, IEC, CE, and SAA certifications, making them suitable for use in both domestic and industrial applications.The relays have several safety features, such as a built-in double-contact; the two contacts that open and close when the relay is switched on and off. This ensures that if one contact fails, the other will still remain active and guard against any potential short circuit or other problems. In addition, the relays are designed to be used with a wide variety of different configurations, allowing them to be adapted to a variety of different applications.In conclusion, the 8021-69000 series of power relays is an efficient and effective type of relay designed for use in high-power applications. It has a high switching capacity, a double-contact safety feature, and can be connected to various configurations. The relays have also been certified for use in many countries, making it an ideal choice for both domestic and industrial applications.
