Circuit breakers are an important component of modern electrical systems. They are used to protect electrical circuits and circuits from overcurrents, short circuits, and other electrical problems. The 219-3-40110-20 circuit breaker is a unique miniature breaker that features a switchable trip sensor.

Application Field

The 219-3-40110-20 circuit breaker is suitable for use in residential and commercial buildings, as well as in industrial facilities. It is typically used in distribution boards and motor control centers, where it provides protection against overload, short circuits, and ground faults. The breaker is also suitable for use in some electrical equipment, such as distribution transformers, air compressor systems, and motor starters.

Working Principle

The 219-3-40110-20 circuit breaker works on the principle of thermal-magnetic protection. When the temperature of the connecting circuit sees an increase due to the current passing through it, a thermal-magnetic switch inside the breaker trips, opening the circuit and thereby preventing damage or fire due to overcurrents. The switch is spring-loaded and can be adjusted to trip at different loads. Additionally, this breaker can be equipped with a trip monitor which monitors the circuit for overcurrents, short circuits, and ground faults.

The 219-3-40110-20 circuit breaker has been designed for use in areas with high humidity, high temperature, and strong vibrations. It is well-suited for use in residential areas as well as in industrial and commercial premises. The occurrence of over-currents is minimized by the trip switch and the trip monitor. Additionally, the circuit breaker is equipped with a reset switch that can be used to reset the breaker when it has tripped due to an overload or a short circuit.

Other Features

The 219-3-40110-20 circuit breaker also has several other features that make it suitable for use in demanding applications. The case of the breaker is made of flame-retardant thermoplastic, and it has an impact rating of up to IK10. The breaker also has a UL-listed Trip Unit that helps it meet the safety and reliability standards of UL and CSA. Additionally, the breaker is available with a number of accessories such as a shunt trip co-ordination device, a cable common extending facility, and a trip free alarm switch.

The 219-3-40110-20 circuit breaker is designed for maximum safety and reliability, making it ideal for use in residential, commercial, and industrial applications. It provides reliable protection from overloads, short circuits and ground faults. It also features a spring-loaded trip switch and a trip monitor, as well as a reset switch and other accessories. And because it is rated for high temperatures, high humidity, and strong vibrations, it is suitable for use in a variety of applications.
