Single-pole protection function: 1P design, specially used to protect the fire wire in single-phase circuits, when the current in the circuit exceeds the rated value, it can quickly cut off the fire wire, effectively preventing overheating of wires, damage to electrical appliances or even fire and other dangers caused by overloading, and providing accurate overcurrent protection for single-phase electrical equipment in the home, such as lighting fixtures, small fans, chargers, etc., to ensure the safe operation of the equipment and wiring, to Extend the service life of electrical appliances and reduce the risk of electrical accidents.
Wide Voltage Adaptability: With a wide voltage range of 230V - 400V, it can adapt to the normal fluctuation of household power supply voltage as well as the voltage changes in some special circumstances. In the unstable voltage environment of different regions and different times, it can still operate stably and reliably, ensure the effective protection of the circuit, reduce the damage to the electrical equipment due to voltage abnormality, and provide continuous and stable protection for the household electricity, so that you don't need to worry about the impact of voltage fluctuations on the electrical equipment.
Sensitive overcurrent protection mechanism: Built-in high-precision current detection device, with high sensitivity to the current changes in the circuit. Once the detected current exceeds the set rated value, the circuit breaker will immediately and automatically trip and cut off the power supply, the action is quick and precise, can respond to the overcurrent situation in an instant, effectively prevent the safety hazards caused by overcurrent, provide timely and effective protection for the safety of home electricity, ensure the safety of life and property of you and your family.
3. Product use scene
Home Lighting Circuit: In the home lighting system, it is used to protect all kinds of lamps and lanterns, such as chandeliers, ceiling lamps, wall lamps, table lamps and so on. Lighting fixtures in the process of use, may be due to bulb aging, poor line contact and other reasons lead to increased current, DZ47-60 1P circuit breaker can monitor the current in real time, when the current exceeds the rated value quickly cut off the power supply, to prevent damage to the lamps and lanterns due to overcurrent, and at the same time to avoid electrical accidents caused by the failure of the lamps and lanterns, to ensure normal use of the family lighting for daily life, to provide a safe and comfortable lighting environment. The lighting circuit of small electrical appliances: applicable to the circuit of small electrical sockets.
Socket circuit for small electrical appliances: It is suitable for connecting socket circuits for small electrical appliances, such as mobile phone chargers, electric fans, electric irons (low power), electric shavers, etc. These small electrical appliances are relatively low-power appliances. These small electrical appliances, although relatively low in power, may cause current overload when used simultaneously or when malfunctioning. The circuit breaker can protect these socket circuits individually, cutting off the power supply in time when the current rises abnormally, protecting the sockets and connected electrical equipment, preventing local circuit problems from affecting the electrical safety of the whole family, and giving you more peace of mind when using small electrical appliances.
Home renovation and electrical renovation: in home renovation or electrical renovation projects, it is an essential basic electrical component. Whether it is the electrical wiring of a new house or upgrading the electrical system of an old house, the DZ47-60 1P circuit breaker can be reasonably configured according to the family's electricity needs and provide reliable overcurrent protection for single-phase circuits. It can perfectly cooperate with other electrical components (such as switches, sockets, distribution boxes, etc.) to create a safe, stable and efficient electrical environment for the family, to meet the growing demand for electricity in modern families, and to improve the quality and safety of family life.
4. Product use instructions
Preparation before installation:
Carefully check the appearance of the circuit breaker for defects such as breakage, deformation, contact oxidation, shell cracks, etc. If there are any problems, contact the supplier for replacement in time to ensure that the quality of the DZ47-60 1P circuit breaker used is intact and undamaged.
Determine the installation position of the circuit breaker according to the layout of the home distribution box and the design requirements of the electrical system, and prepare suitable installation tools, such as screwdrivers, spanners, sharp-nosed pliers, etc., to ensure the precision and applicability of the tools, so as to avoid damage to the circuit breaker during the installation process.
Installation and connection:
Install the DZ47-60 1P circuit breaker on the guide rail of the distribution box, make sure it is firmly installed without looseness. In accordance with the wiring plan of the electrical system, connect the fire wire to the input terminal of the circuit breaker (usually marked with ‘L’), pay attention to the correctness and firmness of the wiring to avoid the situation of connecting the wrong wire or false connection. After the wiring is completed, use a screwdriver to tighten the screws on the terminals to ensure that the wires are in close contact with the terminals and to prevent heat, fire or malfunction due to poor contact.
Debugging and Testing:
After completing the installation and wiring, close the circuit breaker to check whether it can work properly. 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 the overcurrent situation to test whether the protection function of the circuit breaker is sensitive and reliable. For example, you can observe whether the circuit breaker can trip within the specified time by gradually increasing the load current until it exceeds the rated current of the circuit breaker. 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 inspect and maintain the circuit breaker to see if there is any abnormality in its appearance, such as heat, smoke and odour. 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 tripping 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.
