AGW-2

AGW-2 Application Field and Working Principle

AGW-2 is an overload protection switch produced by Siemens. It is mainly designed for use in low voltage switchgear to protect against overload and short circuit.

The AGW-2 switch consists of two main parts; a thermal device and an electromechanical device. The thermal device is responsible for measuring temperature and providing overload current protection by tripping the switch when the temperature exceeds a specific threshold. The electromechanical device is what makes the switch operational by physically switching the circuit on and off when the necessary control signals are received.

The switch can be specified to trip at temperatures between 75°C and 100°C, depending on the application requirements. For example, if a motor is being used, the switch would be sized and set to trip at a lower temperature to provide protection from overloads caused by heavy starting or stopping of the motor.

AGW-2 switches are usually designed to be manually reset, either with a switch lever or a reset button. When the switch trips due to an overload, the switch will need to be reset in order to restore power to the area or device that was being protected.

The AGW-2 application field includes industrial and commercial applications, including distribution systems, motor control, and lighting control systems. Additionally, they are used to protect appliances such as stoves and water heaters, where it is important to quickly identify faults and disconnect power in the event of an overload.

In order to ensure reliability, it is important to choose the correct size of AGW-2 switch for the application. An undersized switch may be unable to provide adequate protection and an oversized switch may cause nuisance trips, leading to prolonged outages.

Overall, the AGW-2 switch is suitable for use in low voltage applications where overload and short circuit protection is needed. It is reliable, easy to install, and comes in various sizes to suit different applications.
