Circuit breakers are essential devices within an electrical system; they are designed with the purpose of protecting an electrical circuit from excessive current which could result in excessive heating, and eventual fire. It’s important to know the different types of circuit breakers available, and the application fields and working principles behind them.

LELZXK121-1REC5-35241-50-G1-V is a particular circuit breaker and is best suited for establishments such as shopping centers, office buildings and restaurants, or anywhere a medium-level usage of voltage is expected. It has a medium voltage classification, meaning it can handle any voltage between 691 and 890 volts with a current rating of up to 1000 amperes.

The working principle behind the LELZXK121-1REC5-35241-50-G1-V circuit breaker is that it can detect abnormal current that is greater than the expected current and immediately disconnect the circuit. It is designed so that it trips rapidly in the event of an overload, thereby effectively protecting the circuit. It also has a manual reset switch, which allows the user to reset the circuit breaker and restore the power after an overload has been detected, provided that the cause of the overload is removed.

The LELZXK121-1REC5-35241-50-G1-V circuit breaker also includes an optional electrical interlock feature, which ensures it trips at the same time as other breakers when a major fault is present. This ensures all breakers within the same system will trip in the event of a fault, ensuring the entire system is protected. Another benefit of its electrical interlock feature is that it prevents the circuit from being closed until all interlocked breakers are in the closed position. This helps to prevent accidents from occurring.

The LELZXK121-1REC5-35241-50-G1-V circuit breaker also includes an optional shunt trip device, which can be used to selectively de-energize the circuit breaker in the event of an emergency. This is especially useful in applications where a manual reset may not be possible, such as in a smoke-filled room.

In summary, the LELZXK121-1REC5-35241-50-G1-V circuit breaker is an extremely versatile and reliable device that is suitable for establishments such as shopping centers, office buildings, and restaurants. Its medium voltage classification, current rating, manual reset switch, and optional electrical interlock and shunt trip features make it an ideal circuit breaker for protecting against electrical faults.
