Circuit Breakers – UPG211-2REC4-4949-3 Application Field and Working Principle

Circuit breakers are among the most common components of an electrical system. As the name implies, their purpose is to monitor the electricity flowing through a circuit and cut the power in the event of an overload or short circuit - preventing further damage to the equipment or potentially injury to those working on the system. The UPG211-2REC4-4949-3 circuit breaker is just one example of the hundreds of models available on the market today. The UPG211-2REC4-4949-3 is designed primarily for AC protection. It’s rated for 240V/277V, 24kA interrupting rating, and features adjustable trip settings along with long-time, short-time, and instantaneous curves. The unit also offers plug-in connection, wide-set terminals, and an adjustable thermal magnetic trip unit. An important part of understanding the UPG211-2REC4-4949-3 is understanding how it works. The unit utilizes thermal and magnetic action to identify and break an overload or short circuit. It’s designed to open when the load current exceeds the adjustable trip setting.When electricity is applied to the circuit, the heat from its current pushes the thermal portion of the breaker beyond the predetermined triple point. This can happen if the current reaches a dangerous level, or even if the current increases too quickly. Once the thermal portion trips, a magnetic trip element is activated, which pulls an armature away from a contact, breaking the power. To reset the breaker, the button on the front of the unit needs to be pushed. Doing so causes a cam to turn and a spring is put under pressure. The current must be reduced to a safe level for the spring to release and the circuit to reset.The UPG211-2REC4-4949-3 circuit breaker is ideal for a variety of settings, but especially in electrical systems. Its adjustable tripping settings make it easy to tailor the protection it provides, and its ability to react quickly helps ensure that systems, as well as the people operating them, are kept safe. With these features, the UPG211-2REC4-4949-3 is a dependable and reliable option for circuit breakers.
