The circuit breaker is one of the most simplest and common electrical devices in virtually all industrial or residential applications. It is an important component of any electrical system, as it can help to protect the system from damage due to overloads or short circuits. One type of circuit breaker is the 9911801105, which is an automatically operated electrical switch. This device is used to both, interrupt and resume the electric current, thus protecting the installations and people from potential danger.

The 9911801105 is also known as a thermal-magnetic circuit breaker. It is designed to cut the circuit if there is overload and effective for overload, short circuit and automatic re-closing protection. The 9911801105 circuit breaker is a device containing both thermal and electrical components. It utilizes the thermal component to detect overloads and the magnetic component to detect short circuit conditions. When excessive current is detected, this will supply a trip signal to the circuit breaker which causes it to trip and disconnect the circuit.

The working principle of 9911801105 circuit breaker is based on two different physical phenomena, known as the thermal reaction and electrical action. As current flows through the circuit, a resistor placed in series with the contacts generates heat. This generates a thermal effect on the main contacts; the temperature of the contacts varies with the current it is carrying. The greater the current, the greater the heat, and vice versa. When the temperature of the contact reaches a predetermined level, the spring mechanism separating the contacts is triggered, and the contacts snap open, breaking the circuit. Additionally, the high temperature of the contact caused by the overcurrent will cause a thermal magnetic device placed within the circuit breaker to activate and open the circuit as well.

In order to protect a circuit from overloads and short circuits, the 9911801105 circuit breaker is a reliable and effective device that is suitable for industrial, naval and domestic applications. When not exposed to excessive current, the circuit breaker does not provide protection, but when excessive current is detected, it is able to provide the needed protection. By disconnecting the circuit, it prevents equipment damage, personal injury, and other possible safety hazards. It is also able to reset itself automatically, allowing the circuit to resume electrical flow.

The 9911801105 circuit breaker is a reliable device that has a wide range of applications, from industrial to domestic. It is used in power distribution systems, motors, and light fixtures, among many others. It uses two different physical phenomena for overload and short circuit protection, thus providing efficient and reliable protection for many different types of circuits. This circuit breaker is an important component for any installation, and its reliability and safety features make it a valuable asset for any electrical system.
