Circuit Breakers are common devices which are used to regulate electrical circuits. The 219-2-21241-3 circuit breakers are one type of circuit breaker with specific applications and working principles.

The 219-2-21241-3 circuit breaker is a thermal-magnetic breaker which has both an adjustable bi-metallic temperature sensing element and a chromium alloy magnetic field sensitive element. It is a three-pole, DIN-rail mountable breaker with a rated current of 10A, rated voltage of 400V and a capacity of 23kA. It has adjustable trip characteristics which allow it to be set up to respond to minor changes in the system that may cause an overload. It is also equipped with a release that can be manually opened or closed. The design and construction of this breaker make it suitable for applications in high temperature environments where air is not present, as well as dusty and humid places.

The working principle of the 219-2-21241-3 circuit breaker is based on the combined operation of its two separate elements, namely, the temperature sensing element and the magnetic field sensitive element. The temperature sensing element senses the current flowing through the circuit breaker and then increases its temperature due to the Joule heating effect. When the temperature of the element reaches a certain threshold, it activates a microwave bimetal strip which in turn closes a contact in the circuit, thus opening the circuit and protecting it from damage. Simultaneously, the magnetic field sensitive element reacts to changes in the magnetic field, which can be caused due to different external activities or fluctuations in the current passing through the circuit breaker. When this element detects a disturbance in the field, it also activates the release and shuts down the circuit breaker.

The 219-2-21241-3 circuit breaker can be widely used in industrial and commercial applications such as HVAC, lighting, security, and medical systems. It is also often used in water pumping systems and control panels, as well as in production and manufacturing processes where circuit protection is essential. In addition, it can also handle short-circuits with ease and is suitable for emergency power systems, adjustable speed drives, and solar-powered solutions.

The 219-2-21241-3 circuit breaker is a safe, robust, and reliable device that has been designed to protect circuitry from overloading and other electrical faults. It is a convenient and simple tool which can be quickly installed and adjusted to suit a wide range of electrical applications.
