Circuit breakers are devices used in electrical systems to protect them from an overload of current that could cause damage to the system. They come in two main types – thermal and magnetic – and each has its own unique working principles. Today, we’ll be focusing on one type specifically – the 219-4-21294-1 circuit breaker.

The 219-4-21294-1 circuit breaker is a thermal-type breaker designed for applications where space is limited. It features a unique compact design that provides excellent circuit protection without sacrificing performance or reliability. In addition, it has a low insertion force contact design, which makes it easy to install in tight spaces.

The working principle of a 219-4-21294-1 circuit breaker is based on thermal magnetic theory. The device is equipped with a bimetallic strip which is composed of two different metals with different thermal coefficients. This strip is connected to a thermal sensor which triggers the circuit breaker in the event of an overload. When the current flows through the strip, it causes the two materials to expand at different rates due to their different thermal coefficients. This differential expansion causes the strip to bend, which in turn activates the thermal sensor. The sensor then triggers the circuit breaker, which cuts off the flow of current and prevents possible damage to the system and its components.

The 219-4-21294-1 circuit breaker has a number of key features which make it ideal for certain applications. It is suitable for both AC and DC installation, and is rated for up to 600 volts and 10 amps. In addition, it has a wide operating temperature range of -40 to +85 degrees Celsius. The device is also UL approved and CSA listed, making it safe to use in many different types of applications.

Overall, the 219-4-21294-1 circuit breaker is a great choice for applications where space is limited. It has a compact design that allows it to fit into tight spaces, and its thermal magnetic working principle makes it reliable and highly effective. In addition, it is UL approved and CSA listed, making it a safe device to use in a variety of applications. All of these features make the 219-4-21294-1 circuit breaker an excellent choice for a range of applications.
