A circuit breaker is a switch-operated electrical device designed to quickly and safely interrupt an electrical circuit in the even of an overload or short circuit. The T11-2-15.0A-31976-2 is a specific type of circuit breaker manufactured by Siemens. It is a two-pole device with a current rating of 15A and a switching capacity of 36 KVA.

The T11-2-15.0A-31976-2 is primarily used for the protection of low voltage electric motors, lighting circuits, and other electrical circuits in industrial and commercial applications. It is designed to trip and open the circuit when a short circuit or an overcurrent occurs, preventing overloading and other potential hazards.

The working principle of the T11-2-15.0A-31976-2 is fairly simple. It includes an electromechanical mechanism which is calibrated to trip when a certain current is applied. The device\'s switching capacity is determined by the current and time settings of the internal trip mechanism, and the trip time and current rating are factory-set and cannot be adjusted by the user.

The T11-2-15.0A-31976-2 is designed to trip within 4-7 ms under normal overload conditions, and within 0.04-0.07 s under short circuit conditions. It is also designed to carry a 3-phase rated operation with AC voltage up to 250V, and a single-phase with AC voltage up to 415V.

The T11-2-15.0A-31976-2 is designed to be reliable and robust, and it is fitted with a variety of features and accessories to ensure proper operation. These include anti-pumping and anti-sequencing functions to prevent unnecessary tripping, as well as various methods of visual indication and alarm signals.

Overall, the T11-2-15.0A-31976-2 is a reliable and efficient circuit breaker from Siemens. It is primarily used for the protection of low voltage electrical circuits and motors, and is designed to provide quick, safe and efficient interruption of the current when an overcurrent or short circuit is detected, preventing accidents and expensive equipment damage.
