The LELH11-1RS4-63F-5.00-AF-01-V circuit breaker is an automatic current-limiting circuit breaker that is designed to handle a range of short-circuit currents in applications that require robust protection and performance. It is part of the LELH11-1RS4 family of circuit breakers, which are medium-voltage, load-interrupting, single- or double-pole devices.

The circuit breaker design allows a wide range of short-circuit currents up to 20 to 30 times the rated current to be safely interrupted. These circuit breakers include a trip unit designed to automatically interrupt any over-current event that exceeds the device’s rated trip setting.

UL-certified LELH11-1RS4-63F-5.00-AF-01-V circuit breakers offer a wide range of safety features, including an adjustable trip unit, adjustable short-circuit current rating, and adjustable protection settings. This combination of features ensures that the circuit breaker is able to safely handle all short-circuit current demands that are within its range.

The working principle of the LELH11-1RS4-63F-5.00-AF-01-V circuit breaker is based on the concept of current limiting. Current limiting helps to protect the circuit breaker from damage due to short-circuit current and helps to reduce the duration of the over-current event.

The trip unit works by sensing any changes in the current flowing through the breaker. When the current rises above the rated trip setting, the breaker trips and quickly interrupts the current. This interrupts the flow of electricity through the circuit, helping to protect the circuit from damage.

The LELH11-1RS4-63F-5.00-AF-01-V circuit breaker is commonly used in applications that require robust protection and reliable performance. Common applications include industrial plants, power plants, transformer stations, marine systems, high-rise buildings, and oil and gas production plants.

The LELH11-1RS4-63F-5.00-AF-01-V circuit breaker is also a popular choice for large commercial and industrial applications that require reliable, robust protection and performance. These applications include industrial manufacturing, power generation, petrochemical plants, and electrical service.

The LELH11-1RS4-63F-5.00-AF-01-V circuit breaker is extremely reliable and offers many features that help to maximize safety and performance. It is designed to be easy to install and operate, and is UL-certified for use in a wide range of applications. The combination of safety and performance features make this circuit breaker an excellent choice for any commercial or industrial application that requires reliable protection and performance.
