Whether you are upgrading your home's electrical system or simply looking for a reliable circuit protection solution, the DZ47-60 3P Circuit Breaker will bring you peace of mind.
2. The main characteristics of the product
Three-phase circuit protection: 3P poles design, specially designed for the protection of three-phase electrical appliances and circuits in the home. It can accurately monitor the three-phase current, and when any phase has an overcurrent or short-circuit fault, it will quickly cut off the circuit of that phase to avoid the fault from spreading to the other phases, effectively protect the normal operation of three-phase electrical appliances (e.g. central air-conditioners, three-phase electric ovens, etc.), prevent damage to the equipment due to electrical malfunction, prolong the service life of the equipment, and safeguard the safety and stability of the home power supply at the same time.
Wide voltage adaptability: with a wide voltage range of 230V - 400V, it can easily cope with normal fluctuations in household power supply voltage as well as voltage variations caused by regional differences and peaks in electricity consumption. Whether in a stable urban grid environment, or in rural or remote areas where the voltage may be less stable, it can operate stably and reliably, ensuring that the circuit breaker is always in an effective state of protection, reducing the damage caused to electrical equipment due to voltage abnormalities, and providing continuous and stable protection for household electricity consumption.
Efficient overcurrent and short-circuit protection mechanism: Built-in advanced current sensing and stripping device can quickly and keenly detect overcurrent and short-circuit conditions in the circuit. Once the current exceeds the rated value, the circuit breaker will automatically trip and cut off the power supply in a very short time, effectively preventing the wires from overloading and heating up to cause a fire, as well as protecting the electrical equipment from being damaged by the impact of the short-circuit current, providing a reliable protective barrier for the safety of home electricity use and keeping you and your family away from the threat of electrical accidents.
3. Product use scene
Family three-phase electrical protection: In the family, it is used to protect large electrical equipment with three-phase power supply, such as central air-conditioning systems, electric heaters (three-phase power supply type), industrial-grade home baking equipment, large commercial kitchen appliances (some of which are three-phase power supply), etc. These equipments have large power and safety requirements. These equipments are of high power and require high stability and safety of the circuit.DZ47-60 3P circuit breaker can monitor the circuit condition in real time to ensure that in the process of equipment operation, once there is an electrical fault, it can quickly cut off the power supply to avoid damage to the equipment and potential safety risks, and ensure the safe and stable operation of the equipment, so that you can use these high-power electrical appliances with peace of mind to enhance the comfort and convenience of family life. Convenience.
Home renovation and electrical upgrading: It is an indispensable key component in home renovation or electrical system upgrading projects. When you are adding new three-phase electrical equipment, replacing old wiring, or upgrading the entire electrical system to meet the increasing demand for electricity, the DZ47-60 3P circuit breaker becomes the ideal choice for safeguarding the safety of the new electrical system due to its reliable performance and convenient installation. It can perfectly cooperate with other electrical components to create a safe and efficient electrical environment for the family, making your renovation or upgrade project more perfect and providing a solid guarantee for the future life of family electricity consumption.
Electrical system renovation in old houses: For electrical system renovation in old houses, replacing circuit breakers with good performance is one of the most important steps to improve electrical safety. The original old circuit breaker may be due to outdated technology or long-term use and performance degradation, can not meet the needs of modern families with electricity, DZ47 series circuit breakers, especially this DZ47-60 3P model, can replace the old circuit breakers, significantly improve the protection ability of the home electrical system, effectively deal with the risk of electrical failure due to the increase in the number of electrical equipment, aging and other reasons for electrical safety for the old house. Protect and escort, so that residents living in old houses can also enjoy a safe and reliable power supply.
4. Product use instructions
Commissioning and Testing:
After completing the installation and wiring, the circuit breaker is operated by closing the circuit breaker to check whether it can work normally. Professional electrical test instruments, such as multimeters, can be used to measure the voltage, current and other parameters of the circuit to ensure that the circuit is properly energised and that the circuit breaker can accurately monitor and protect the circuit. At the same time, simulate overcurrent and short-circuit conditions to test whether the protection function of the circuit breaker is sensitive and reliable. For example, the load current can be gradually increased until it exceeds the rated current of the circuit breaker, and observe whether the circuit breaker is able to trip within the specified time; or use short-circuit test equipment to artificially create a short-circuit fault, and check whether the circuit breaker is able to quickly cut off the power supply. If problems are found, the wiring, current settings and internal structure of the circuit breaker should be checked in time and adjusted and repaired accordingly.
Precautions for use:
Regularly check and maintain the circuit breaker to see if there is any abnormality in its appearance, such as heat, smoke, odour, discolouration of the shell. At the same time, check the wear of the contacts, if the contacts are found to be severely worn or ablated, the contacts or the whole circuit breaker should be replaced in time to ensure its normal opening and closing performance and protection function. It is generally recommended to carry out comprehensive inspection and maintenance every certain period of time (e.g. half a year or one year), and the specific time interval can be determined according to the actual use environment and frequency.
When operating the circuit breaker, follow the correct operation method to avoid damage to the circuit breaker caused by barbaric operation. Before closing the circuit breaker, ensure that there is no short-circuit or earth fault in the load circuit; after opening the circuit breaker, wait for a certain period of time (usually a few minutes) before closing the circuit breaker, so as to avoid any danger caused by the residual charge present in the circuit. In addition, do not force the circuit breaker to close when it is in a faulty tripping state; remove the cause of the fault first and ensure that the circuit is restored to normal before carrying out the closing operation.
Avoid the circuit breaker to be affected by humidity, high temperature, corrosive gases, strong vibration and other harsh environments, if the installation environment is poor, corresponding protective measures should be taken, such as the addition of protective cover, ventilation device, shock pads, etc., in order to prolong the service life of the circuit breaker and ensure the stability of its performance. At the same time, attention should be paid to avoid the accumulation of debris around the circuit breaker, to keep its surrounding environment clean and well-ventilated, to facilitate heat dissipation and operation and maintenance.
