Circuit breakers are essential tools for protecting electrical equipment from hazards caused by excess current or voltage. The LELHK11-37590-50 is a particular type of circuit breaker designed for use in medium voltage applications. It has the ability to quickly shut off power to a circuit before any significant damage can occur. In this article, we\'ll go over what makes the LELHK11-37590-50 unique, its application field, and the principles behind its working.

Unique Features of the LELHK11-37590-50

The LELHK11-37590-50 has a number of features that make it an ideal choice for medium voltage applications. First, it has a maximum short circuit breaking capacity of 50kA at 380V AC. This high rating offers maximum protection to any equipment. Second, it has an incredibly fast response time when detecting faults. This is important, as fast response to a fault is key to preventing significant damage. Third, the mechanical lifetime of the contact stem is 50,000 operations or more. This allows it to be used for a variety of applications without the worry of the contact stem failing. Finally, its small size provides easy installation in any area.

Application Field

The LELHK11-37590-50 is designed primarily for use in medium voltage applications. This includes a variety of industrial and commercial applications such as substations, power plants, and marine vessels. Due to its high protection, fast response time, long lifetime, and small size, it is an excellent choice for these medium voltage applications.

Working Principles

The LELHK11-37590-50 is a type of molded case circuit breaker. This type of circuit breaker is designed to quickly detect faults and shut off the current to a circuit in order to protect the electrical system. It does this by using an electromagnetic trip unit that can detect and respond to sudden increases in current. When the trip unit detects an increase in current, it releases a coil spring which trips the circuit breaker and turns off the power. The LELHK11-37590-50 is unique in that its trip unit has a very fast response time, which is vital in preventing damage to the circuit.

Conclusion

The LELHK11-37590-50 is a high-quality, molded case circuit breaker designed specifically for use in medium voltage applications. Its features, such as a high short circuit breaking capacity and fast response time, make it an excellent choice for any medium voltage application. Additionally, its fast response time and long lifetime provide a level of protection that is unmatched. As such, the LELHK11-37590-50 is an excellent choice for any medium voltage application.
