Circuit breakers are designed to control and protect electrical circuits and equipment from short circuits, over-currents, overloads, and other faults. The 3120-F311-P7T1-W15LY3-15A circuit breaker is a type of industrial switch used to implement fault protection and prevent damage and component failure. This circuit breaker is capable of interrupting an overload or short-circuit current, which is of crucial importance when dealing with hazardous, high-voltage electrical systems.

The 3120-F311-P7T1-W15LY3-15A is a three-pole, thermo-magnetic type circuit breaker. This type of breaker receives its tripping power from both thermal and magnetic effects in the contacts. The thermal effect is generated through contact welding at high temperatures due to excess current in the circuit. The magnetic effect is generated by the force of a solenoid, powered by the circuit current, which deflects the lever.

The 3120-F311-P7T1-W15LY3-15A has the following application fields and capabilities: it is used for overload and short-circuit protection at the secondary level of distribution and for parallel circuits, it has adjustable current settings, and it is designed to meet IEC and UL standards. It is suitable for residential, industrial, and commercial use for applications such as motor protection, short-circuit interruption, protective switching, and load-balancing. It also has a high short-circuit breaking capacity, making it a highly reliable and efficient device.

The working principle of the 3120-F311-P7T1-W15LY3-15A is relatively straightforward. When a circuit is connected to the 3120-F311-P7T1-W15LY3-15A, it is closed, allowing an electric current to flow without interruption. If an overload or short-circuit current is detected, the internal components of the circuit breaker heat up, causing it to trip and open the circuit. This interrupts the flow of current and prevents further damage to both the device and the circuit.

In addition, the 3120-F311-P7T1-W15LY3-15A is designed with safety features to protect personnel from electric shock caused by sudden electrical surges. It has Built-In Safety System (BISS), which is an integrated circuit breaker, and External Test Facility (ETF). The BISS detects impulse current overloads and trips the breaker automatically, while the ETF provides for manual trip testing of the circuit breaker in order to assess its functioning and condition.

The 3120-F311-P7T1-W15LY3-15A circuit breaker is a reliable and safe device used in a variety of applications, including residential, commercial, and industrial. Its adjustable current settings make it an excellent choice for controlling and protecting electrical circuits and equipment. The built-in BISS and ETF systems provide additional safety and reliability, and its ability to interrupt overload and short-circuit current makes it a great choice for protecting and controlling electrical circuits.
