APL111-1865-1 Application Field and Working Principle

Circuit breakers are devices that are used to interrupt the flow of electricity or current when overloaded or short circuited. The APL111-1865-1 is a type of circuit breaker made by ABB that is classed as a miniature circuit breaker (MCB). The APL111-1865-1 is designed to protect residential and commercial electrical systems from malfunctioning or overload. It is designed to detect the presence of an overload or short circuiting and trip its contacts, so as to quickly and safely disconnect from the power grid, thus preventing further damage or possible risk of electrocution. An APL111-1865-1 device typically has a fuse to activate the tripping mechanism and usually comes with thermal protection as well.The APL111-1865-1 circuit breaker works by monitoring the amount of current passing through it. When a fault occurs or the current exceeds the safe limit, the circuit breaker trips and cuts off the power. The APL111-1865-1 can be used as a single-pole breaker or as a double-pole breaker, depending on the current rating of the device and the requirements of the system.When a short circuit occurs, the current flowing through the circuit is far in excess of the normal rating of the circuit and will cause an excess heat build-up that may cause damage to the circuit. The APL111-1865-1 has an adjustable thermal protective device which will activate if the temperature of the circuit exceeds the preset limit, causing the circuit breaker to trip.The APL111-1865-1 is also equipped with a mechanical switch which is activated whenever the current rating is exceeded, causing the breaker to trip and disconnect the circuit from the electricity supply. This switch also disconnects the power when it is manually opened or closed.The APL111-1865-1 is ideal for use in residential and commercial electrical systems as it is a miniature circuit breaker. This makes it ideal for environments where space is limited, such as in back-up systems, or in industrial or commercial installations. The APL111-1865-1 is also suitable for light force automated switching systems.The APL111-1865-1 is a reliable and efficient device that provides protection from electrical faults and is easy to install. It is highly recommended for residential and commercial electrical systems, where it can prevent electrical fires and ensure safety.
