Circuit Breakers

LELB1-1REC5-34716-1-V circuit breakers are used commonly in many industrial and domestic circuits. They are designed to detect and respond quickly to an overtemperature or overcurrent situation, automatically cutting off the electrical supply to the circuit and protecting the electrical devices connected to it. This type of circuit breaker is especially useful when dealing with large and complex circuits, offering effective protection and excellent performance.

Application Field and Working Principle

LELB1-1REC5-34716-1-V circuit breakers are suitable for a wide range of applications in industrial, commercial and domestic settings. With regard to their working principle, LELB1-1REC5-34716-1-V circuit breakers are designed to act as a switch, responding to an overcurrent or overtemperature situation by automatically cutting off the power to the circuit. The specific operations can be managed through the internal programming, allowing for different protections and settings based on the specific situation.

The circuit breaker consists of two main components, the contactor and the thermal breaker. The contactor is responsible for making and breaking the circuit, while the thermal breaker is responsible for regulating the temperature of the contacts during its operation. When the preset limit is exceeded, the thermal breaker will open the contacts, cutting off the power to the circuit. This process helps protect the circuit and its components from overcurrent and overtemperature situations.

LELB1-1REC5-34716-1-V circuit breakers also have the ability to reset and restore the circuit when the conditions have returned to a normal range. This reset action allows the device to be used again after the situation has been resolved and the device can then be reset to its normal operating parameters. The reset feature also helps to prevent a burned out circuit, as the heater in the thermal breaker can trip, cutting off the current flowing through the circuit and eliminating any chance of a fire.

Another important feature of LELB1-1REC5-34716-1-V circuit breakers is their integral surge protection. Surge protection devices are designed to protect electrical circuits from sudden, large rises in voltage. The inclusion of surge protection in these circuit breakers helps to protect the devices connected to the circuit, avoiding potentially dangerous outcome scenarios such as electrical fires.

In conclusion, LELB1-1REC5-34716-1-V circuit breakers are specifically designed to respond quickly to an overcurrent or overtemperature situation, automatically cutting off the power to the circuit and protecting the electrical devices connected to it. This type of circuit breaker is especially useful when dealing with large and complex circuits, offering effective protection and excellent performance, as well as integral surge protection and reset capabilities.
