Circuit breakers are essential to the functioning of any kind of system, from the household wiring in your home to the large-scale power grids that provide electricity all over the world. They provide an overcurrent protection by interrupting the current flow when a potentially hazardous situation is detected. The R21-42-15.0A-B161CH-S circuit breaker is specially designed to provide an optimum level of protection and reliability.

The R21-42-15.0A-B161CH-S is a three-pole AC circuit breaker which is certified for both HVAC and DC applications. This breaker has been designed with a “chassis-mounted” support that allows it to be mounted in various ways, making it a great option for many different applications. It features a built-in ground wire which allows it to be connected directly to the power source, providing an added layer of safety for the user.

This breaker is designed with a “trip-free” feature that allows it to automatically reset after a fault has been detected. This helps to ensure the system continues to function even when a fault has occurred. It also features an adjustable trip point which allows users to customize the breaker’s response time in order to better meet specific needs. The breaker also utilizes an over-temperature sensor which helps protect against thermal damage.

In terms of its working principle, the R21-42-15.0A-B161CH-S works by detecting excessive current and then opens the circuit. This is done by the contactors housed within the breaker, which are responsible for connecting and disconnecting the current to the circuit. When the contactors detect an overcurrent, they cause an arc to form between the contacts, resulting in a “trip” that interrupts the flow of current and prevents potential damage.

The applications of the R21-42-15.0A-B161CH-S are many and varied, making it a great choice for many different purposes. It is especially well-suited for use in high-voltage and direct-current applications, such as in power grids, manufacturing plants, and other larger-scale energy transmission systems. It is also a great option for use in more common applications, such as in home wiring, office buildings, and other light electrical needs.

The R21-42-15.0A-B161CH-S circuit breaker is an ideal choice for anyone looking for a reliable and safe circuit breaker. It features a sturdy design and multiple features which ensure maximum protection from potential hazards, making it the perfect choice for a wide range of applications. Whether you’re looking for a reliable protection for your household wiring or for a large-scale power grid, the R21-42-15.0A-B161CH-S is the perfect circuit breaker for the job.
