Power Relays, Over 2 Amps

T9AV1D12-12 is a type of high current overload relay that is increasingly popular in industrial and some residential applications. It is a commonly used and often preferred type of relay due to its ability to protect both devices and other people from overload hazards. It is used in all sorts of applications, is durable and reliable, and is easily customizable.

Application Field

The use of T9AV1D12-12 is primarily for overload protection and switching control. It can be used to control the current of motors such as AC and DC motors, compressors, generators, and other electric machines used in industrial settings. This unit is also popularly used for high current switching applications in residential applications, such as for on/off light switching, and in electric shower systems.

Working Principle

The T9AV1D12-12 overload relay works by monitoring the current passing through it. It has two inputs, a “reference sensor” and a “control sensor”. The reference sensor connects directly to the line voltage and notices if the voltage level goes above or below an acceptable threshold. If the voltage reach a predetermined level, the control circuit is activated, and the overload relay will operate.

Once the control circuit is activated, the current going through the overload relay will be sent to a circuit breaker. The breaker will then be activated and will interrupt the current and thereby protect the device from harm. The breaker also has a built-in reset button that, once pressed, will allow the device to be turned back on.

If the current going through the relay does not reach the set maximum, then the control circuit will remain deactivated and the overload relay will not operate. This feature is beneficial to protect devices from damage due to low current. The overload relay is also equipped with a varistor rating that can be adjusted depending on the requirements of the application.

Advantages

The T9AV1D12-12 overload relay has many advantages. Since the control circuit is deactivated when the current does not reach the maximum level, it prevents users from when the device is shut down. The built-in reset button ensures that the device will return to the correct operation if the current reached an acceptable threshold. Additionally, since the current can be easily switched on and off, it makes it easy to switch the device from one purpose to another.

The T9AV1D12-12 also has a variety of adjustable features to meet the varying demands of different application requirements. The varistor rating can be easily adjusted to meet the requirements of heavy-duty industrial applications, as well as for the residential applications mentioned earlier. In addition, the original model also comes with a built-in current amplifier for more reliable overcurrent detection.

Conclusion

The T9AV1D12-12 relay is a reliable, durable, and versatile type of relay that is popular for overload protection and switching control in industrial and residential applications. It has all the features necessary to easily meet the requirements of diverse applications, including adjustable varistor ratings and built-in current amplifier and reset features. Thanks to its innovative and robust design, it is sure to provide excellent service in any environment.
