LELBXK1-34973-1-V Circuit Breaker: Application Field and Working Principle

Circuit breakers are among the most important safety components in any electrical system. They are designed to disconnect and isolate parts of the system in order to prevent overload, short-circuit and other potentially dangerous faults. The LELBXK1-34973-1-V circuit breaker is a type of circuit breaker used in certain industrial and commercial applications.

The LELBXK1-34973-1-V is an air-operated circuit breaker that combines high current capacity in a oil-filled housing to provide a safe, reliable and durable fault protection system. It is designed to trip an individual circuit or a group of circuits in the event of a short-circuit, overload or ground fault. It is suitable for both single- and three-phase applications with a rated current up to 200A and a maximum voltage rating of 1000V. It is also available in OPF (manual override) and non-OPF (automatic) configurations.

The LELBXK1-34973-1-V offers a wide range of features, making it an ideal choice for many industrial and commercial applications. It is designed to be fail-safe and can be used as a main switch or an auxiliary switch. It features an adjustable setpoint, allowing it to be tailored to specific applications. It includes both visual and audible signaling devices to indicate tripped circuit conditions. It also provides added protections through its optional built-in arc-fault protection circuit.

The LELBXK1-34973-1-V works by automatically sensing faults and then tripping the circuit. This is achieved by utilizing a current transformer that continually monitors the current flow in the circuit. When the current exceeds the rated value, the current transformer causes the contacts to rapidly disconnect the circuit. This eliminates the need to interrupt the power manually, which would require someone to manually open the circuit.

The LELBXK1-34973-1-V is an extremely robust and reliable circuit breaker suitable for a wide range of industrial and commercial applications. It is designed to protect against overloads, short-circuits and ground faults, ensuring the safety and reliability of an electrical system. It features adjustable setpoints, several signaling and control features, as well as optional built-in arc-fault protection, making it one of the most popular circuit breakers available.
