H3AM-NS-A-300 AC100-240

Time delay relays are widely used in many modern control system applications, often as part of a larger system, but they can also be used for stand-alone applications. The H3AM-NS-A-300 AC100-240 is an excellent example of a time delay relay, designed for continuous loads, specifically for applications with one or two motors. This time delay relay is designed to protect motors from overload and excessive temperature, as well as to provide a timer function for both starting and stopping motors. In this article, we will discuss the application field and working principle of the H3AM-NS-A-300 AC100-240 time delay relay.

The H3AM-NS-A-300 AC100-240 time delay relay is typically used in industrial and commercial applications, particularly those that involve motors. The time delay capability can be used for both starting and stopping motors, which can help to extend the life of the motor. The time delay function can also be used to protect against overload situations or to provide a delay before turning on or off a motor. The AC100-240 voltage range also makes the H3AM-NS-A-300 ideal for use in many industrial and commercial applications.

The H3AM-NS-A-300 time delay relay has two different operation modes, Normal and Normal Close. In the Normal mode, the contacts of the relay close after the timing delay has expired. This is the most common mode of operation and is generally used for applications that require a delayed start. In the Normal Close mode the contacts do not move until the time delay elapses, and then the contacts open, which can be used for applications that require a delayed stop.

The time delay on the H3AM-NS-A-300 can be adjusted from between 0.1 seconds to 5 minutes, depending on the application. The relay is also designed to be adjustable so that the time delay can be tailored to the specific application. This time delay can be set by adjusting a potentiometer on the relay, which can be done remotely using an on-board digital display.

The H3AM-NS-A-300 time delay relay also features an integrated overload protection circuit. This circuit monitors the current draw of the motor and automatically trips when an overload situation is detected. This helps to prevent motor burnout caused by overloads, which can be an issue in some industrial and commercial applications. The overload protection circuitry also has an adjustable trip delay which can be used to further tailor the protection to the specific application.

Overall, the H3AM-NS-A-300 AC100-240 is an excellent time delay relay, designed for continuous loads, particularly applications with one or two motors. It has a wide range of features, including adjustable time delays, overload protection, and adjustable trip delay, making it ideal for many industrial and commercial applications. The H3AM-NS-A-300 is also a relatively low cost time delay relay that can be easily adjusted to suit the requirements of the specific application.
