Circuit breakers are the most common type of switchgear in use today. In fact, most of our power equipment and electronic devices are fitted with circuit breakers. They are important pieces of electrical equipment that are designed to protect people, equipment, and homes from power surges and overloads. R21-1-7.50A-34020-4-V is an example of a circuit breaker. This article will cover the application field and working principle of the R21-1-7.50A-34020-4-V circuit breaker.The R21-1-7.50A-34020-4-V circuit breaker is designed for industrial applications. It is used to control and protect electrical systems such as motors, pumps, compressors, generators, and other high voltage equipment. The circuit breaker is designed to disconnect the power supply and the designated load when an overcurrent or overload occur, or when a short circuit or ground fault is detected.The R21-1-7.50A-34020-4-V circuit breaker is designed with a voltage rating of 15kV, dielectric withstand of 28kV, and current ratings of 10-40A. It is UL listed and has a unique ON/OFF latch mechanism. The ON/OFF latch mechanism is designed to enable the user to manually open the circuit breaker quickly and easily in an emergency situation.The working principle of the R21-1-7.50A-34020-4-V circuit breaker is based on the principle of thermal-magnetic operation. Thethermal-magnetic operation of the R21-1-7.50A-34020-4-V circuit breaker involves the sensing of both heat and current. The circuit breaker essentially consists of a bimetallic strip, which is heated by the current passing through it which causes the strip to bend, and this in turn trips a switch. The magnetic field created by the current passing through the circuit breaker also impacts the movement of a separate magnetic field, which in turn activates a lever to trip the switch.When an overcurrent or overload occurs, the bimetallic strip bends and trips the switch, which in turn disconnects the power supply. The separation of the power supply offers another level of protection as it prevents any damage from occurring to the designated load. Additionally, the R21-1-7.50A-34020-4-V circuit breaker has the capacity to detect a short circuit or ground fault and subsequently cut off the power supply in the same manner.The R21-1-7.50A-34020-4-V circuit breaker is a reliable and effective piece of electrical equipment that is suitable for industrial applications. It can quickly and easily detect overcurrents and overloads, as well as providing an additional level of protection from damage due to short circuits and ground faults. The R21-1-7.50A-34020-4-V circuit breaker has numerous advantages for users, including a manual override latch system to enable emergency intervention and its UL listing for safety.
