Circuit Breakers

3120-F321-P7T1-W04K-20A circuit breakers are small current switches that have been designed to protect electrical circuits from short-circuiting, overpowering, and overloading. They can detect abnormalities and power outages in an electrical circuit, allowing for its safe operation.

Application Field

3120-F321-P7T1-W04K-20A circuit breakers are mostly used in industrial and commercial settings, such as in hospitals, factories, and buildings where safety is a top priority. They are also used to protect residential homes, where electrical usage is often higher than industrial applications. For example, in homes equipped with air conditioners, washing machines and dryers, ovens, and lights, 3120-F321-P7T1-W04K-20A circuit breakers can detect current leakage, short-circuiting, and surges, and automatically shut off the power to the affected area.

Working Principle

At the heart of the 3120-F321-P7T1-W04K-20A circuit breaker is a switch that is triggered and closed by a bimetallic strip mechanism. This strip, heat-sensitive, is made of two different metals that expand and contract at different rates when exposed to heat, or current. When the current flow reaches a certain threshold, the switch is activated, causing the full lead-out wire to change shape and open the circuit. This works to break the circuit, eliminating the risk of damage or fire from current overload.

The 3120-F321-P7T1-W04K-20A circuit breaker comes with an adjustable, manual reset feature that allows it to be manually set to either an open or a closed position. This ensures that the circuit breaker will only activate when the appropriate threshold has been exceeded. It also allows for a more accurate response to power outages, reducing the risk of a delayed response and preventing potential damage.

In addition to its adjustable manual reset feature, the 3120-F321-P7T1-W04K-20A circuit breaker is also equipped with a thermal-magnetic cut-off switch. This feature works to increase the overall safety of the circuit by preventing overloads and short-circuiting, as it immediately shuts off power when the temperature or current increases too much. This works to ensure that the circuit breaker is able to respond quickly and accurately to any unsafe conditions.

The 3120-F321-P7T1-W04K-20A circuit breaker is an essential component for electric appliances, as it helps to protect against electrical damage, fire, and accidents from current overloads and short-circuiting. It is designed to be robust, reliable, and easy to install in any industrial or commercial setting.
