QPPCCBDB07 is a type of common circuit breaker. It is used for a wide range of applications, such as general building utilities, residential areas, and small-load applications. It is designed to protect against overcurrent, short circuit, and ground fault protection. It is also used as an electrical control tool for emergency management, protection against electric shock, and the control of the power supply.

The QPPCCBDB07 uses a high speed steel spring, which is connected to the circuit breaker. This spring is charged to the extreme, and these tensions keep the circuit breaker in the closed position until a certain load exceeds its rated limit. The overload protection is provided by the spring which returns the device to its original position when the overload is eliminated.

The QPPCCBDB07 works according to the principle of displacement. This type of device utilizes the power and the displacement of a movable part. This movable part is connected to a system of bolts and tension rods which are activated when a load is exceeded. Thus, the movable part pushes against the system of bolts and tension rods and lifts the breaker.

The QPPCCBDB07 also provides magnetic protection. It utilizes a magnetic field created by an electromagnet, which is worked upon by a coil. This coil is activated when the current exceeds a certain limit. The coil creates a current which neutralizes the magnetic field created by the electromagnet. This causes the breaker to trip and the circuit is disrupted.

The QPPCCBDB07 also has a low-resistance heat sensor. This is composed of a diode section, which provides over-temperature protection. The device operates normally when the load is within the rated limits. However, when the load is exceeded, the diode section becomes overheated and this trips the circuit breaker.

The QPPCCBDB07 also utilizes a high-resistance thermistor. This is used for the protection against high circuit temperature. The thermistor is connected directly to the circuit and is set to activate when the circuit temperature rises above a certain limit. When the temperature exceeds the rated limit, the thermistor trips the circuit and provides the necessary protection.

Overall, the QPPCCBDB07 is designed to provide reliable and fast circuit breaker protection. It utilizes both electromechanical and electrical protection with high speed steel spring and low voltage heat sensors. This ensures that the circuit breaker is able to handle all types of electrical loads in the most efficient manner.
