Circuit Breakers

Circuit brekers are devices designed to protect electrical systems from overloads and short circuits due to incorrect operation of the system itself. A circuit breaker can offer current-limiting protection and allow for better control of the current flow in order to prevent damage to the system . The LELBXK111-1-61-25.0-M3-V is a specific example of a circuit breaker and its application field and working principle will be outlined in this article.

Application field

The LELBXK111-1-61-25.0-M3-V circuit breaker is a 3-pole, 63A device intended for use in residential, commercial and industrial applications such as hospitals, schools, restaurants, retail stores and other buildings. The LELBXK111-1-61-25.0-M3-V is designed to provide a high degree of protection against short circuits and overloads, as well as against damage from excessive current draw and potential fire hazards. This device also has circuit-opening and -closing characteristics that make it well-suited for temporary power failure situations.

Working principle

When excessive current flows through the LELBXK111-1-61-25.0-M3-V circuit breaker, an internal release mechanism will trip the device, cutting off the electrical circuit and preventing the flow of current. This trip is initiated when the current exceeds the device’s calibrated performance parameters and a deliberate action must be taken to reset it. The LELBXK111-1-61-25.0-M3-V also features thermal overload protection; when the temperature of the device exceeds a predetermined threshold, the circuit breaker will trip and open the circuit to protect the system from overheating and potential fire hazards.

Conclusion

The LELBXK111-1-61-25.0-M3-V circuit breaker is designed to provide high-level protection against both short circuits and overloads, while also offering circuit-opening and -closing characteristics that make it well-suited for use in residential, commercial and industrial applications. The device also features thermal overload protection to guard against overheating and potential fire hazards. As such, it is a highly reliable and cost-effective solution for managing the flow of electrical energy and ensuring the safety of users and equipment.
