Vacuum interrupters are versatile electrical switching devices. They are used in various types of electrical equipment, such as circuit breakers, contactors, and relays. The 120800071 is a vacuum interrupter rated for applications up to 1000V DC. This type of interrupter consists of two main components: a stationary contact and a moving contact. The two contacts are separated by a vacuum gap, which is filled with a special gas. When an electric current passes through the gap, the gas is ionized and causes a spark, which can be used to break the circuit.

The 120800071 is a long-life vacuum interrupter with a very high electrical endurance. It features a minimum number of moving parts for increased reliability. Its rated withstand current is up to 1000A DC, and its rated breaking capacity is up to 500A DC. It is designed for applications in medium voltage switchgear and environment with a current interruption time of 4.0 ms and closing time of 8.0 ms.

The 120800071 working principle is based on the means of vacuum interruption. A vacuum is created in a cylindrical chamber, and two contacts, one stationary and the other moving, are housed in it. When the contacts are closed, direct current passes through the circuit. When the contacts are opened, the circuit is broken by the vacuum between the contacts, which prevents the flow of current. The vacuum interruption eliminates the need for mechanical elements, which increases the lifetime of the device.

The 120800071 is specially designed for use in the industrial environment. It is capable of withstanding extreme temperatures, humidity, shock, vibration, and electro-chemical corrosion. It has been tested for long-term reliability and is also suitable for use in applications that require high breaking and short-circuit breaking capacity.

The 120800071 is also designed for easy installation and maintenance. It comes with a spring latch system, which allows for quick and easy opening and closing of the contacts. This reduces the maintenance time and makes it easier to service the device. It also has a self-cleaning mechanism, which helps to prevent dirt and debris from accumulating on the contacts, which can reduce the performance of the device.

The 120800071 is a robust and reliable device with a long lifetime. It is capable of withstanding mechanical shock, extreme temperatures, and humidity. It also has a high electrical endurance and can operate in a wide variety of applications. It is a cost-effective solution for medium voltage switchgear and environment in industrial applications.
