LEL1-29869-3

Circuit breakers are electrical devices that help protect circuitry from excessive current. They are essential components in any electrical system, whether it is for a commercial, industrial, or residential application. Circuit breakers come in many forms, one of which is the LEL1-29869-3. This popular model has a wide range of applications and a straightforward working principle. This article will discuss this circuit breaker and its underlying concepts.

The LEL1-29869-3 is a highly reliable and robust circuit breaker designed for a wide range of applications. It features three poles, each of which can handle up to 50A at 240V, with a short circuit capacity rating of 10 kA. It is UL listed and CSA certified, making it suitable for residential, commercial, and industrial applications. The circuit breaker also has a low voltage release, both magnetic and thermal, making it ideal for a variety of applications. Additionally, it has a wide range of accessories available, such as auxiliary switches and undervoltage tripping devices, making it a great all-round choice for various applications.

The LEL1-29869-3 is a circuit breaker that works on the principle of overload protection. This means that when the current running through the breaker exceeds its rated value, the device trips, cutting off the power and preventing any damage to the connected circuitry. This is done by the use of a bi-metal strip, which is fitted to the trip bar of the breaker. The bi-metal strip is shaped in a curved manner, and comprises two strips of metal with different coefficients of thermal expansion. This means that when the current running through the breaker exceeds the rated value, the resulting heat causes the metal strips to expand at different rates, resulting in the trip bar being pushed down due to the increased angle of the metal strip. This action triggers the internal mechanism of the breaker, cutting off the power and stopping any potential damage.

The LEL1-29869-3 is a great choice for a wide range of applications, including residential, commercial, and industrial. Its robust design ensures that it is suitable for whatever environment it is installed in, and its low voltage release makes it suitable for use with sensitive circuitry. Moreover, its overload protection principle ensures that any sudden current spikes are quickly dealt with, protecting connected circuitry from any potential damage. Therefore, if you are looking for a reliable and robust circuit breaker that provides a good level of protection, the LEL1-29869-3 is a good option.
