Circuit Breakers

A circuit breaker is a type of switch that is designed to protect electrical circuits from damage caused by overload or short circuit. The LELK12-1REC5-38951-50-G1-V is a specific type of circuit breaker, designed specifically to protect electrical systems in high-voltage installations where space is limited. It provides a high level of safety and meets the strict requirements of the current safety regulations.

Application Field

The LELK12-1REC5-38951-50-G1-V circuit breaker is most commonly used in high voltage installations that require a high level of safety, including nuclear power plants, offshore platforms, and other oil & gas installations. It can also be used in industrial applications, such as in factories and other large-scale industrial settings.

Working Principle

The LELK12-1REC5-38951-50-G1-V circuit breaker works by sensing when the current in an electrical circuit exceeds a certain threshold and then automatically trips to open the circuit, preventing further damage or a possible electrical fire. This threshold can be adjusted, allowing the circuit breaker to be used in applications where the current can vary greatly. When the circuit is tripped, the contactor will automatically shut off power to the circuit, and a signal can be sent to alert staff that there is a problem.

The LELK12-1REC5-38951-50-G1-V circuit breaker uses a thermal-magnetic trip unit to detect when the current in a circuit exceeds the set threshold. The trip unit senses the temperature rise due to the increased current and responds by releasing energy stored in a magnetically-shielded release mechanism. This energy is used to move an internal contactor to open the circuit and shut off power. This process is much quicker than a traditional fuse, providing faster response times and greater protection.

In addition, the LELK12-1REC5-38951-50-G1-V has a built-in protective device that monitors the operating status of the circuit. It will detect any faults in the system and provide an alert or trip the circuit immediately, depending on the type of fault. This ensures that the system is always protected from any potential damage.

Conclusion

The LELK12-1REC5-38951-50-G1-V circuit breaker is a high-quality, reliable piece of electrical protection equipment. It is used in high-voltage installations where space is limited, providing a very high level of safety. The circuit breaker works by sensing when the current in an electrical circuit exceeds a certain threshold and then automatically trips to open the circuit, preventing further damage or a possible electrical fire. It also has a built-in protective device that can detect any faults in the system and provide an alert or trip the circuit immediately should a problem be detected.
