Circuit breakers are devices designed to protect electrical circuits from damage due to over current or short circuit conditions. LELHPK11-1RS4-31840-125-V is one type of circuit breaker.

This medium voltage circuit breaker belongs to 1RS4 family. It has three poles, spring-charged mechanism, and long-travel, direct acting opening tripping. The rated voltage is 12.5kV and it has a rated operating current of 40A.

The LELHPK11-1RS4-31840-125-V can be used in a variety of applications. Its primary use is in industrial and commercial installations such as manufacturing and industrial plants, office buildings, and residential developments. It is also suitable for a wide range of applications such as generator plants, industrial motor circuits, high-current lighting and air-conditioning systems, and power distribution networks.

The main function of the circuit breaker is to protect the system from over current conditions. When an over current or short-circuit current flows through the circuit, the breaker trips and breaks the circuit, thus protecting the system and equipment from damage. It also protects the circuits from damage due to intermittent overloads or sustained overloads, and helps ensure that electrical systems remain safe.

The LELHPK11-1RS4-31840-125-V is designed to sense both over current and short circuit conditions. It has an adjustable trip time setting and a thermal element that gives the breaker the ability to discriminate between loads so it can quickly trip only the circuit that is experiencing the fault. The breaker\'s trip time setting can be adjusted to ensure that the breaker responds quickly enough to trip on a lower level of current than the rated current, thus preventing further damage to the system.

The LELHPK11-1RS4-31840-125-V also has a manual reset feature. In the event of a trip, the breaker will be locked in the off position until the operator manually unlocks it and resets it. This manual reset feature helps prevent any further damage to the system if the fault condition persists and the breaker has to be reset.

Overall, the LELHPK11-1RS4-31840-125-V is a reliable and efficient medium voltage circuit breaker. It is suitable for a variety of applications and provides effective protection against over current and short circuit conditions. It can help ensure that electrical systems remain safe and reliable in a variety of operating environments.
