LEGBX66-36752-30-V Circuit Breakers

Circuit breakers are essential components in the electrical distribution of any powerplant system. Since their first use in the early days of electricity, circuit breakers have constantly improved and become an integral part of modern power distribution systems. LEGBX66-36752-30-V circuit breakers are one of the latest innovations in circuit breaker technology, combining the advantages of older designs with the latest advancements.

Application

The LEGBX66-36752-30-V circuit breaker is used primarily for medium to high voltage (from 2.4kV up to 40.5kV) electrical power distribution networks. Thanks to its robust design, high breaking capacity and long life expectancy, it is suitable for a wide range of applications, including industrial and commercial networks such as hospitals, factories, airports, power grids, and other high-voltage systems.

Structure

The LEGBX66-36752-30-V governs the electrical power distribution using a combination of mechanical, magnetic, and electronic components. The mechanical components provide protection when an external interruption occurs and the breaker trips. The magnetic components, such as a single or double coil trigger system, regulate the thermal and magnetic force of the circuit breaker, allowing it to open, close, and trip the necessary circuit. Finally, the electronic components provide additional protection and control, while enabling the breaker to detect, protect against, and potentially isolate a short circuit or other fault.

Features

One of the primary advantages of the LEGBX66-36752-30-V circuit breaker is its reliable and adjustable electronic protection system. Thanks to this, the breaker can detect and isolate any shorts or overloads that may occur. This makes it ideal for industrial applications, where reliable protection is essential. In addition, the LEGBX66-36752-30-V features a robust frame and vacuum interrupter, and it is capable of achieving high heat dissipation, making it suitable for long-term use in challenging environments.

Working Principle

When a fault occurs, the LEGBX66-36752-30-V quickly identifies it and interrupts the electrical power supply, protecting the network from short circuits or overloaded lines. It does this by detecting the initial voltage or current, and then calculating the fault current. This calculated current is then used to control the breaker’s operation, which is to open or trip the circuit. The LEGBX66-36752-30-V can also operate with a high breaking capacity, meaning it can quickly and reliably isolate or shut off any faults it detects.

Conclusion

LEGBX66-36752-30-V circuit breakers are reliable and high-performing devices that offer superior protection for medium to high voltage circuits. Thanks to their adjustable electronic protection system, strong frame, and high breaking capacity, they are capable of providing reliable and efficient operation for long periods of time. Additionally, their simple design makes them relatively easy to install and maintain. With their robust construction and wide application range, LEGBX66-36752-30-V circuit breakers are an essential component of any power distribution system.
