Circuit Breakers - JLE-2-1-53-3-B4-250-A-V Application Field and Working Principle

Circuit breakers are electrical devices used to detect and isolate faults and to protect equipment and wiring systems from overcurrents. They are designed to react quickly to dangerous faults in an electrical system, in order to minimize the impact of an event. In this article, we will be discussing the application field and working principle of the specific circuit breaker model JLE-2-1-53-3-B4-250-A-V.

Applications

The JLE-2-1-53-3-B4-250-A-V circuit breaker can be used in a range of electrical applications. It is suitable for use in both residential and commercial settings, as well as industrial environments such as oil refineries, energy production and distribution plants and automation and control systems. It is suitable for use with single-phase and three-phase systems, and can handle up to 250 Amps of current.

Working Principle

The working principle of the JLE-2-1-53-3-B4-250-A-V circuit breaker is based on the thermal-magnetic protection system. The device works by monitoring the current flow through the circuit, and if there is an increase in current beyond a preset level (known as the trip point), the circuit breaker will trip and cut the power supply. This trip point is adjustable, and can be set to suit the application, allowing the user to select the level of protection they require. When the current level returns to normal, the circuit breaker can be reset, returning power to the circuit.

The JLE-2-1-53-3-B4-250-A-V circuit breaker also includes a thermal element, which is designed to protect the system from prolonged overcurrent. The thermal protection system works by monitoring the temperature of the contacts, and if the temperature increases beyond a set point, the circuit breaker will trip and cut the power supply. Again, the trip point is adjustable, so the user can choose the level of protection appropriate for their application.

Conclusion

The JLE-2-1-53-3-B4-250-A-V circuit breaker is designed for use in a range of electrical applications. It uses the thermal-magnetic protection system, and is equipped with adjustable trip points that allow the user to select the level of protection required. This makes it a versatile and reliable option for protecting electrical circuits.
