Circuit breakers are important components used in electrical systems. They provide a way to quickly shut off an overloaded circuit, thus preventing damage to other components. The QMB-122-00ENN-3BA is a circuit breaker produced by Schneider Electric, and it is designed for industrial control and power distribution applications. In this article, we will discuss the application fields and working principle of the QMB-122-00ENN-3BA.
The QMB-122-00ENN-3BA circuit breaker can be used in a variety of industrial and commercial applications. It is designed to provide circuit protection and control of AC and DC circuits up to 1000V. It can be used in power distribution and motor control panels, industrial equipment and systems, as well as in computers and similar electronic devices. It is also suitable for use in hazardous locations, where it is certified for use by ATEX and IECEx.
The QMB-122-00ENN-3BA has three poles, with a rated current of 63 A and a trip current of 40 A at 25 degrees Celsius. It is IP20 rated for outdoor use and can operate between -40 to +40 degrees Celsius. It is also UL489 listed and is available with a variety of accessories, including a solar panel. The QMB-122-00ENN-3BA is supplied with a high-grade PTFE cover, which offers protection from mechanical shocks, vibrations, dust and dirt.
The working principle of the QMB-122-00ENN-3BA is quite straightforward. When the current flowing through the circuit is greater than the rated value, the QMB-122-00ENN-3BA trips and the contacts are opened. This prevents further current flow through the circuit, thus protecting it from further damage. The trip current value can be adjusted to account for varying temperatures, or it can be set to trip at a higher than normal current in order to provide additional protection.
The QMB-122-00ENN-3BA also has a number of safety features built in. It is equipped with a thermomagnetic protection element, which allows it to detect any sudden increase in temperature due to an overload or short circuit. When this happens, the magnetic coil kicks in, opening the contacts before the damage is done. It is also protected by a molded case galvanizing, which guards against corrosion and environmental damage.
In summary, the QMB-122-00ENN-3BA circuit breaker is designed for use in a variety of industrial and commercial applications. It offers short circuit and overload protection, with an adjustable trip current. It is protected against mechanical shock, vibration, dust and dirt, and is UL489 approved and ATEX and IECEx certified for use in hazardous locations. Finally, it also has safety features built in, such as a thermomagnetic protection element and a molded case galvanizing.
