Circuit breakers are a specialized type of electrical switch that is designed to protect against overload and electrical short circuits. The JLE-2-1-53-1-B4-200 is an example of a circuit breaker. It is a high voltage type, with a rated voltage of 400V and a rated current of 200A.

Circuit breakers provide an alternate path for electric current when it is overloaded or a short circuit occurs. When the current is too high, the circuit breaker trips, cutting off the electric current and protecting the system from damage or hazards. This is done by interrupting either the electrical resistance within the breaker or the direct connection between the line and the load. Different types of current trips are available, varying in sensitivity and response time.

The JLE-2-1-53-1-B4-200 is a timed delayed-closing current trip breaker. This means that it has a delay setting, which allows it to sense an overload for a period of time before it trips the circuit. This helps to protect against small overloads that may eventually pass, while still quickly responding to larger overloads. It is capable of withstanding medium level short circuit current up to 400kA or 2s.

This type of breaker has a wide range of applications, ranging from power distribution and power plants to shipboard power systems and industrial control and monitoring systems. Additionally, it is used for ground fault and overload protection in areas with high voltage equipment or in cases where safety is critical. Its fast reaction time and adjustable delay make it an ideal choice for managing electricity consumption.

In order to ensure optimal performance, the JLE-2-1-53-1-B4-200 should be installed and operated in accordance with its instructions. These include ensuring that the environment is clean and dry, as well as free from dust and other contaminants. Additionally, maintenance should be regularly performed, and any signs of damage or wear should be addressed immediately.

In conclusion, the JLE-2-1-53-1-B4-200 is a high voltage circuit breaker with a range of uses. It is a timed delayed-closing current trip breaker, providing overload and short circuit protection with adjustable time delay. This breaker is suitable for a variety of applications, from power distribution and industrial control systems to shipboard power systems. Installing and operating this breaker in accordance with its instructions will help ensure its optimal performance and safety.
