Circuit breakers are used in many areas of electrical engineering and industry, ranging from domestic to commercial. Within a certain range, circuit breakers protect electrical systems against overloads and short circuits. Although conventional products come in many forms, the LEG6-39351-3-V is a solid-state circuit breaker designed to provide reliable electrical protection for a variety of applications. In this article, we will discuss the LEG6-39351-3-V application field and working principle.

Application Field of LEG6-39351-3-V

The LEG6-39351-3-V is a miniature vacuum switch, using vacuum sealing technology to achieve isothermal operation and device protection. This type of circuit breaker is typically used in motor protection, relay protection, AUX power supply protection, ac arc protection and other low-voltage power distribution applications. Thanks to its small size, it can be mounted in confined spaces, ideal for applications where space is of the essence. Additionally, the LEG6-39351-3-V offers a high level of overcurrent and short-circuit protection.

This circuit breaker also has excellent resistance to a variety of environmental conditions, such as corrosion, humidity, heat and UV light. This makes it suitable for many applications in industrial and commercial environments, such as electrical control cabinets, medium and low-voltage power distribution systems, and other sensitive equipment.

The LEG6-39351-3-V is also designed to provide minimal reaction time and maximum protection. This type of circuit breaker offers the greatest protection possible and is suitable for continuous and non-continuous operations. The device offers a wide range of switching and disconnecting functions, allowing for maximum control and safety.

Working Principle of LEG6-39351-3-V

The working principle of the LEG6-39351-3-V is very straightforward. When an overcurrent or short-circuit occurs, the circuit breaker is triggered and the vacuum chamber is opened. This vacuum chamber, which is sealed containing noble gases, is mounted on top of a bimetallic strip. When the strip is heated by an overcurrent, it will bend and eventually open the vacuum chamber. This will cause the air inside to expand, cooling the device and increasing the resistance, thereby tripping the breaker. The breaker can also be reset manually by pressing the reset button.

The LEG6-39351-3-V also has a number of important safety features. For one, it has a particularly low resistance, allowing it to serve as an indicator of the surge protection level. Additionally, it is equipped with an emergency overload trip system, which immediately trips the breaker in case of an emergency.

The LEG6-39351-3-V is a capable and reliable circuit breaker with a wide range of applications. Its low-resistance and quick reaction time make it suitable for use in industrial and commercial environments, where space constraints may be an issue. The device is designed to provide maximum protection and safety, and the flexible switching and disconnecting functions enable users to control and protect the system.
