Circuit Breakers

A circuit breaker, or CB, is a device used to protect electrical systems, networks, and components from damage caused by excess current. Circuit breakers are crucial components in any electrical system as they are designed to prevent electrical circuits from becoming overloaded or short-circuited, which can cause fires and other serious electric shocks. In this article, we’ll take a look at the application field and working principle of the 3500-F11-P10-5A circuit breaker.

Application Field

The 3500-F11-P10-5A circuit breaker is designed for applications with up to 2000 amperes of current. It is commonly used for lines up to 600 volts direct current, 400 volts alternating current, and 60 hertz. It is also suitable for use in motor control centers, motor starter protection, transformer protection, distribution centers, and other general-purpose applications. It is also suitable for overcurrent protection of sensitive electronic equipment.

Working Principle

When the current passing through the 3500-F11-P10-5A circuit breaker exceeds the specified overload current value, the circuit breaker trips and interrupt the current flow. The trip mechanism includes an electromagnet and mechanical operating elements. When the current passing through the breaker reaches a certain predetermined level, the electromagnet produces a force that actuates the operating elements and trips the circuit breaker. The trip current of the breaker is adjustable, so that it can be set to trip at different points, depending on the application it is being used for.

The 3500-F11-P10-5A circuit breaker is designed to trip quickly and reset automatically. It features a two-part operating mechanism, the snap switch and trip lever. When the overload current is exceeded, the snap switch trips first, then the trip lever, which severs the circuit. The reset lever allows for manual resetting, if necessary. This two-part operating mechanism provides a fast, precise trip response, which minimizes the risk of damage caused by short-circuiting or power surges.

The 3500-F11-P10-5A circuit breaker is widely used in commercial and industrial applications, due to its ability to provide reliable protection to sensitive electrical equipment. It is easy to install, comes pre-set with trip and reset settings, and offers adjustable overcurrent protection. It is also widely used in residential applications, where it provides additional protection to electric appliances, lights, and other circuits.
