A circuit breaker is a device that prevents the flow of electricity in an electrical circuit or wiring system. It is usually used as a safety measure to make sure that electrical circuits do not malfunction in the event of an overload. The 3120-F521-PTT1-W02D-20A circuit breaker is designed for use in industrial, commercial and residential wiring systems. It is a two-pole circuit breaker, meaning it can handle two separate circuits in one device.The 3120-F521-PTT1-W02D-20A circuit breaker is a unique model that is not available in other types of circuit breakers. It is especially designed for use in outdoor switchgears and semi-outdoor applications. It is a trip-free device, meaning it can not be locked out manually. The trip-free feature ensures the protection of the electrical system by allowing the circuit breaker to automatically trip when an overload or fault occurs.The 3120-F521-PTT1-W02D-20A circuit breaker is designed with a ground fault detection system. This system is designed to detect any abnormal currents in the ground line that could potentially cause a short circuit or overload. The ground fault detection system also helps prevent damage to the building\'s wiring system. When a ground fault is detected, the circuit breaker will trip and shut off the power before any damage can occur.The 3120-F521-PTT1-W02D-20A circuit breaker features an adjustable thermal overload protection setting. This feature allows the user to adjust the amount of current that is allowed to pass through the circuit breaker. This is helpful in protecting the electrical system from potential damage caused by too much current passing through the device. The thermal overload protection setting also reduces the risk of a fire due to too much electrical current passing through the circuit breaker.The working principle of the 3120-F521-PTT1-W02D-20A circuit breaker is based on the principle of resistance. The circuit breaker works by limiting the amount of current that passes through the device when it is activated. When the current flowing through the circuit breaker reaches a certain level, a trip that interrupts the circuit is triggered. This trip cuts off the power supply, preventing further damage from occurring due to an overload or short circuit.The 3120-F521-PTT1-W02D-20A circuit breaker is designed for use in a wide range of applications, including switchgear, transformer stations, substation protection, and more. It is designed to be used in a variety of temperatures, from -30°C to +45°C, making it suitable for almost any environment. The 3120-F521-PTT1-W02D-20A circuit breaker is UL and CSA approved, meaning it has been tested for safety and quality.The circuit breaker is a must-have device for any wiring system, providing protection against overloads and short circuits. The 3120-F521-PTT1-W02D-20A circuit breaker offers reliable protection and is suitable for use in a variety of settings. It is an ideal choice for industrial, commercial, and residential wired systems.
