Circuit Breakers

The LEG11-36386-1-V circuit breaker is an advanced device for safely and reliably protecting electrical circuits. It uses two solid state contactors, or magneto-thermal switches, to interrupt the flow of current when necessary. Due to its outstanding performance and unique features, it is especially suitable for high reliability applications such as telecommunications, metering, building automation, and industrial automation.

Application Field

The LEG11-36386-1-V circuit breaker is designed to protect industrial and commercial applications against short circuits and ground faults. Its features include high breaking current and voltage, mounting flexibility, and an AC/DC functionality that can be used with most electrical systems. Its highly reliable and economical design makes it an excellent choice for many applications, such as:

• Telecommunications
• Metering
• Building Automation
• Industrial Automation
• Data Centers
• Solar Installations
• Test and Measurement Equipment

Working Principle

The LEG11-36386-1-V circuit breaker is made up of two independent magneto-thermal switches, also known as contactors. When the current passes through one contactor, a magnetic field is induced in the internal coil, which causes the mechanical movement of the contactors. This, in turn, opens the contacts, interrupting the current flow. During the course of normal operation, the contactors close again and the circuit is re-established. In the event of a fault condition, the contactors remain open and the circuit is disconnected.

For added safety, the LEG11-36386-1-V circuit breaker is designed to open the connection in a controlled manner and is capable of providing short-circuit protection up to two times rated current. The device also provides no-trip trip current, making it suitable for larger circuits with more current. Additionally, the contactors are designed to withstand more than 500,000 operations and are capable of operating at high temperature without any performance degradation.

Conclusion

The LEG11-36386-1-V circuit breaker is a highly reliable and efficient device that is suitable for a number of industrial, commercial, and residential applications. Its advanced magnetic-thermal switching technology allows it to provide protection against short circuits and ground faults and its robust construction ensures long-term reliability and performance. As such, it is an excellent choice for many applications, particularly those with high currents or loads.
