Circuit breakers are mechanical switching devices within electrical systems. They are designed to safely disconnect circuits when certain conditions arise, such as when there is a power overload or short circuit. Circuit breakers are usually located within circuit boards, such as the QMB-123-00ENN-3BA.

The primary purpose of a circuit breaker is to protect a circuit from excessive current. Many devices, such as the QMB-123-00ENN-3BA, contain a mechanism that allows them to automatically trip or open when too much current is detected. This helps prevent damage to the circuit, as well as to other connected devices and appliances.

In the case of the QMB-123-00ENN-3BA circuit breaker, the device can be used to detect both alternating current (AC) and direct current (DC). When the internal structure of the circuit breaker detects a current that exceeds its rated current level, it will trip or open. This causes the breaker to go from a closed state to an open state and stop the flow of power to the circuit. The amount of current that causes the breaker to trip is adjustable and is referred to as the device\'s "pick-up" setting.

The QMB-123-00ENN-3BA circuit breaker also includes a reset switch. This allows the device to be closed manually after it has opened due to an overload or short circuit. The reset switch also allows the device to be manually closed after maintenance or power outages.

Another feature of the QMB-123-00ENN-3BA circuit breaker is its internal thermal overload protection. This allows the device to detect when the circuit is beginning to overheat and immediately shut off the current to the circuit to prevent further damage. This feature is also adjustable and can be adjusted to the specific needs of the circuit.

The QMB-123-00ENN-3BA circuit breaker is designed for industrial applications. The device is commonly used in commercial machinery and production systems, as well as in other areas of the industrial world. Generally, these types of circuit breakers are not suitable for residential applications.

The QMB-123-00ENN-3BA circuit breaker is an effective and reliable way to protect electrical circuits from overloads, short circuits, and thermal overloads. The device is designed to meet international safety standards and is simple to install and use. As a result, the QMB-123-00ENN-3BA is an ideal choice for industrial applications that require reliable and efficient circuit protection.
