APG2-9739-6 is a type of circuit breaker which is commonly used in industrial applications, such as systems that require an efficient way to detect a circuit overload and cut off the power. It is a suitable choice for a wide range of applications, such as residential, commercial, or industrial applications.

The APG2-9739-6 is a two-phase circuit breaker. It has two main parts – the contacts and the coupling assembly B. The contacts are responsible for making and breaking the electrical connection when the current rises to the predetermined level. The contact part consists of two contact points and four spring plates. The four spring plates are connected to the four contact points. They provide the necessary pressure to ensure a reliable connection between the contact points and the load. The coupling assembly B consists of a relay and a contactor. The relay monitors the current flow and detects when the predetermined level has been reached. The contactor is used for disconnecting the power from the source when the current reaches the predetermined level.

The working principle of the APG2-9739-6 is quite simple. When the current rises to the predetermined level, the relay in the coupling assembly B triggers the contactor to open the circuit. This stops the flow of electricity. The contact points then break the connection between the load and the source. This prevents further damage to the electrical system and helps to protect the equipment from incurring damage due to overheating or an overload.

APG2-9739-6 circuit breakers are usually used in power systems that operate with the help of a capacitor bank. This is because the capacitors can store energy and release it rapidly when needed. This helps to prevent further damage from occurring when the current exceeds the set current levels. They are also used in power systems that have a large number of electrical devices connected to them, as they can detect an overload and cut the power quickly before serious damage occurs.

The APG2-9739-6 circuit breaker is an efficient and reliable device for protecting the equipment or electrical system from damage due to an overload. It is relatively easy to install and requires minimal maintenance. The device can detect current levels accurately and disconnect the power quickly to prevent any further damage from occurring.
