Breaker operation and application

Breakers have a very important role in people's daily life, and can play a role in protecting the circuit. How does a circuit breaker work? How to operate the breaker correctly and safely? The experts of Instrument World World Network below will introduce to you the operation and application of breakers in daily life.

The function of the breaker

The function of the breaker is to periodically switch off the primary loop of the ignition coil, which is generally composed of an electric shock and a de-energized cam. The breaker contacts are made of tungsten alloy. One contact is a fixed contact and the other contact is a movable contact.

The fixed contact ground is fixed by fastening screws on the movable bottom board and the lower fixed bottom board. The contact gap can be adjusted by turning the eccentric screw; the movable contact is fixed on one end of the contact arm and the other side of the contact arm is. One end is sleeved on the pin, the contact arm is pressed against the power-off cam by a spring piece, and the contact arm is connected to the insulated terminal on the outside of the housing via the spring piece and the wire. The number of lobes of the power-off cam is the same as the number of cylinders of the engine, and the power-off cam is integrated with the dial plate and mounted on the distributor shaft. The centrifugal weight of the centrifugal advance mechanism is driven by the distributor shaft.

DZ47 circuit breaker is a miniature circuit breaker, commonly known as air switch. It is a kind of plastic shell circuit breaker. It is a terminal protection device that is most widely used in the construction of electrical terminal equipments in buildings. It is used for single-phase and three-phase short circuit, overload, and overvoltage protection up to 125A, including unipolar 1P, 2-pole 2-pole, 3-pole 3-pole, and 4-pole 4-pole.

The DZ47 circuit breaker has the advantages of excellent and reliable circuit breaker performance, high segmentation capability, and quick tripping. The DZ47 circuit breaker saves time and effort for your home renovation thanks to its small form factor and placement in your home pz30 distribution box. DZ47 circuit breaker shell and components are made of imported high flame-retardant and shock-resistant plastic, energy saving and environmental protection, long service life, bring a strong guarantee for the safety of household electricity!

DZ47 circuit breaker is suitable for lighting distribution system (C type) or motor distribution system (D type), mainly used for AC 50Hz/60Hz, unipolar 220V, second, third, and quadrupole 400V, current to 60A line From overload and short circuit protection, it is also possible to switch off electrical devices and lighting circuits infrequently under normal conditions. When the operating current in the circuit exceeds the rated current, short circuit, voltage loss, etc., the DZ47 circuit breaker automatically cuts off the circuit to prevent electrical fire.

The above is the simple operation and application of the breaker in daily life. There are many types of breaker and it is used in many occasions. Everyone can understand the breaker in practical application.
