Power relays are an essential component in a wide variety of applications, such as industrial machinery, automotive systems, aircraft and HVAC systems, in which the controlling of voltage and current is required. Among them, the BR246D-320A2-28V power relay is special for its outstanding features and good performances. This article briefs the application areas and working principles of this type of power relay.

Application Field

The BR246D-320A2-28V power relay has a wide range of applications. It is an ideal choice for industrial control systems, automation and security, as well as power supply for tests and measurements, motor control, and climate control. It can also be used for switching logic circuits, or signal-intensive systems.The BR246D-320A2-28V power relay is also suitable for contactor positions where greater mechanical strength is needed. It is perfect for on/off switching of circuits up to twenty-eight volts, while its excellent performance makes it perfect for stringent industrial applications. Its surge capability and high reliability make it suitable for tough environments, such as protection circuit applications.

Working Principle

The BR246D-320A2-28V power relay uses a mechanical system comprising an electromagnet which attracts a movable contact when energised. The design of it is much simpler than other types of relays, so users can easily install and maintain the relay.The contact is connected to an actuator which, once attracted by the electromagnet upon energisation, pulls the contact open or closed, depending on the direction of the current flow. This action makes or breaks the desired circuit.The power relay is provided with a high-performance micro-gap contact, which ensures significant reductions of contact resistance and very low contact resistance. This micro-gap contact design also reduces the amount of metal ions which could be transferred to the contact surface, which extends the relay’s life significantly.In addition, the power relay’s coil is hermetically sealed, which ensures that the electromagnet remains insulated from external shock, vibration, or other environmental conditions.

Conclusion

The BR246D-320A2-28V power relay is ideal for industrial control systems, automation and security, as well as power supply for tests and measurements, motor control, and climate control. Its hermetically sealed electromagnet ensures that the relay remains insulated from external shock, vibration, or other environmental conditions. Its high performance micro-gap contact provides a significant reduction of contact resistance and very low contact resistance, so that it can handle both low and high current levels with excellent reliability and minimal maintenance cost.
