Circuit Breakers are devices used to protect electrical equipment from short circuits and overloads. The R11S-4-9.00A-39508-9 is one type of circuit breaker designed to provide protection against short circuits and overloads. It is a professional grade circuit breaker designed to meet the needs of industrial and commercial applications.

The R11S-4-9.00A-39508-9 is a two pole circuit breaker that is UL listed and rated to carry up to 9A at 120/240V AC. It has an electronic trip mechanism that responds to both overloads and shorts with a time delay of up to one hour before tripping. It has an adjustable current setting so that it can be adjusted to meet the specific requirements of the application. The circuit breaker also has an open neutral capability, so it can be used in installations where the neutral is not connected to the electrical panel.

The working principle of the R11S-4-9.00A-39508-9 is that it is designed to respond to both short circuit and overloads. When a short circuit occurs, the current level in the circuit exceeds the circuit breaker’s rating and the electronic trip mechanism trips, interrupting the current flow and thus protecting the electrical equipment from potential damage. With overloads, the current level in the circuit is not as high as with a short circuit but is still high enough to cause damage to the electrical equipment. In this case, the time delay mechanism allows the circuit breaker to trip at a predetermined time before the current flow causes any damage.

The R11S-4-9.00A-39508-9 circuit breaker is suitable for a wide range of applications such as air conditioners, water heaters, ovens, furnaces, fans, pumps, and other heavy appliances. It can be used in a variety of commercial and industrial settings including restaurants, grocery stores, factories, and other businesses. The adjustable current setting makes it suitable for both single and multi-phase applications.

In summary, the R11S-4-9.00A-39508-9 is a two pole adjustable-trip circuit breaker designed to offer protection against short circuits and overloads in commercial and residential applications. It has an adjustable current setting and an open neutral capability and is UL listed and rated to carry up to 9A at 120/240V AC. The electronic trip mechanism responds to both overloads and shorts with a time delay of up to one hour before tripping.
