Circuit breakers are commonly used in nearly all electrical systems, whether residential, commercial or industrial, as they are a critical component of any system’s safety equipment. The R21-62-23.0A-36259-12-U is the designation for a particular breaker made by a company called Square D. This breaker offers some unique features and specifications that make it ideal for certain applications.

The R21-62-23.0A-36259-12-U is an air-blast circuit breaker. It is designed to work with a minimum input of 480 volts AC and a maximum input of 600 volts AC. It has a maximum current rating of 800 amps and a continuous current rating of 500 amps. The breaker is UL 489 listed, indicating that it has been tested for safe operation in accordance with the industry standard. It also has an adjustable short-time delay feature that allows users to control how long the breaker remains open before tripping.

This breaker is typically used for industrial applications, primarily in the automotive, train and aerospace industries. It is suitable for applications where a high-current load is present and where a reliable, fast trip time is required. The difference between the R21-62-23.0A-36259-12-U and other breakers is that it is designed to provide a very quick trip time, as low as 0.005 seconds, giving users the ability to react quickly to over-current situations while offering enhanced safety and reliability.

The working principle of the R21-62-23.0A-36259-12-U is relatively simple. When a current overload situation occurs, the breaker’s internal mechanism trips and causes the contacts to separate. This interrupts the flow of current, thus protecting the system from damage. The breaker is designed to “sense” over-currents and trip quickly in these instances.

The breaker also offers a number of other features that make it a good choice for industrial applications. The breaker is designed to be extremely reliable; it has been tested to withstand over-voltage, under-voltage and short-circuit conditions without failure. It also features adjustable instantaneous trip characteristics, allowing users to fine-tune the breaker’s performance. Additionally, it has an UL-rated 100% ground fault rating, indicating that it will trip quickly in the event of a ground fault current situation.

The R21-62-23.0A-36259-12-U is an ideal choice for industrial applications that require a reliable, quick-tripping circuit breaker. Its adjustable short-time delay feature and other features make it an ideal choice for high-current loads in the automotive, train and aerospace industries. By offering fast trip times and enhanced safety and reliability, this particular circuit breaker offers peace of mind to users.
