Circuit Breakers are electrical devices designed to protect electrical circuits from damage caused by excess current. They are designed to open the circuit when a predetermined current level is exceeded, allowing you to re-start the circuit without permanently damaging the components. There are numerous different types of circuit breakers available for various applications, such as the 279-1-35864-20.

279-1-35864-20 Application Field and Working Principle

The 279-1-35864-20 is a type of circuit breaker used for residential, commercial and industrial applications. This circuit breaker is commonly used for protecting electrical lines from emissions sources, such as lightning strikes or power surges. The breaker works by first detecting changes in the current in the line, and then breaking the circuit when a certain level is exceeded.

This type of circuit breaker works based on the principle of thermal expansion. It uses a thermal element, such as a resistor, to measure the current flowing through the circuit. When the current reaches a predetermined level, the resistance in the thermal element increases, resulting in a rapid increase in temperature. This rapid temperature increase causes the contacts of the circuit breaker to rapidly expand, breaking the circuit and preventing further damage.

The 279-1-35864-20 is rated for 5-15A circuit protection and is UL489 compliant. It is available in various formats, including single pole, double pole and triple pole breakers. It is also available in various voltage classes, ranging from 120VAC to 600VAC. The breaker is easy to install, using only a single screw. It is very reliable and offers a high level of safety.

The 279-1-35864-20 is a reliable and effective circuit breaker that offers a high level of protection from over-currents and power surges. It is easy to install and use and is available in a variety of formats. This type of circuit breaker provides a cost-effective and reliable way to protect electrical components and circuits from damage due to excessive current.
