Circuit breakers are essential safety devices in electrical systems, protecting people and equipment from the danger of electric shocks and short circuits. The LEGBX11-1-61-15.0-M3-V circuit breaker is no exception. In this article, we will discuss the application field and working principle of the LEGBX11-1-61-15.0-M3-V.

The LEGBX11-1-61-15.0-M3-V is a type of Protistor® circuit breaker designed for use in medium voltage power systems. With the ability to operate reliably at 1000 volts, it is ideally suited for heavy industrial use, including industrial installations, buildings, factories, substations, etc. It works by automatically opening the circuit when short circuit or overload currents exceed the safe operating limit to prevent damage to electrical equipment and protect against shock and fire hazards. Additionally, the LEGBX11-1-61-15.0-M3-V is equipped with a pressure-sensitive valve that opens the breaker when the peak current exceeds a preset value.

The working principle of the LEGBX11-1-61-15.0-M3-V consists of a series of checks and balances. Firstly, when a fault occurs in the system, the current rises quickly and the volt-ampere curve of the downstream components begins to rise sharply. When the peak current reaches the breaker\'s trip value, it triggers an electromagnetic relay, whose quick-acting contact disconnects the protected circuit almost instantly. Secondly, a pressure-sensitive valve may be used. This valve senses changes in pressure due to the increase in current and opens up to ensure the circuit is safely disconnected. Finally, the pressure-sensitive valve may be combined with a thermal overload relay to give additional protection. This relay monitors the temperature of the circuit, and opens the circuit breaker if the temperature exceeds a predetermined limit.

The LEGBX11-1-61-15.0-M3-V is a reliable, compact and robust circuit breaker, designed to protect against short circuits and overloads. With its safety features, it ensures people and equipment are kept safe from the jeopardy of electric shocks and other dangers. We hope this article has helped to provide an overview of the application field and working principle of this particular circuit breaker, enabling you to make an informed decision when choosing the right circuit protection device for your needs.
