A circuit breaker is a device used in electrical systems to interrupt an existing electrical circuit in order to protect its associated components from damage due to overloads or short-circuiting. Commonly referred to as a CB, breaker, or a fuse, this device has a much longer lifespan than its counterparts, the fuse and the switch. Depending on the specific make or model, the circuit breaker is set to trip when the current reaches a predetermined level, thus protecting the components from damage or failure. A common application of this device is in residential homes and offices, where it is used to protect electrical appliances from damage or malfunction caused by overloads, surges or short circuits.

The 2907516 circuit breaker is a three-phase breaker commonly used in medium and heavy commercial applications such as data centers, industrial process plants, power distribution systems and power transformers, among others. It is designed to interrupt short-circuit currents while offering the highest level of protection against overloads and faults. The breaker’s operation is based on a thermal-magnetic principle, meaning that it relies on both temperature and current levels to detect fault conditions. The current level is indicated by a bimetallic strip which increases in temperature when the current level increases. When this temperature reaches a certain level, the strip will trip and the breaker will open, resulting in an interruption of the circuit. This ensures that the circuit is not overloaded and that the associated electrical components are protected from damage.

The 2907516 breaker features a wide range of operating current levels, from 5 to 17,500 amps, and has an interrupting rating of 25,000 amperes at 480 V AC, and 35,000 amperes at 600 V AC. Depending on the specific make and model, the breaker is capable of providing thermal or overload protection with adjustable trip settings and a fixed instantaneous trip element. The breaker is also designed to allow for adjustment of the timing of the thermal curve and shifting of the instantaneous trip or overload setting for additional protection. Depending on the application and the need for protection, this breaker can be equipped with a wide range of accessories to ensure the highest level of safety. These accessories include under and overvoltage protection, remote control and telecommunications, and shunt release.

The 2907516 circuit breaker is designed to provide the highest level of protection to associated electrical components by breaking off the circuit when abnormal current levels are detected. Through its thermal-magnetic principle and its wide range of accessories, this breaker can provide a flexibility and safety that cannot be obtained with other types of circuit breakers. This combination of protection and flexibility make the 2907516 circuit breaker an ideal choice for numerous applications in medium and heavy commercial settings.
