1. Product core introduction
HomeDIYer presents DZ47-60 2P small household air switch circuit breaker for 230V - 400V voltage range, which belongs to DZ47 series circuit breakers. This product is mainly used for the protection of household electrical circuits, which can effectively prevent overcurrent and short-circuit situations and ensure the safety of all kinds of electrical equipment and electrical circuits at home.
2. The main characteristics of the product
Two-pole protection design: Adopting 2P poles, it can protect both the fire wire and the zero wire at the same time, which is suitable for single-phase electrical equipment and circuits in the home. This design can effectively monitor and control the current in the circuit, when there is an overload or short-circuit fault, it will quickly cut off the fire line and zero line, preventing fire or damage to electrical equipment due to the persistence of fault current, providing comprehensive safety protection for single-phase circuits in the home and ensuring the safety of electricity.
Wide voltage operating range: it can operate stably in the voltage range of 230V - 400V, adapting to the fluctuation of household power supply voltage. Whether in a normal voltage environment, or in the period of unstable voltage due to the peak of electricity consumption, power system failure and other reasons, it can reliably protect the circuit, avoiding damage to electrical appliances due to abnormal voltage, and guaranteeing the normal service life and stable operation of household electrical equipment.
Sensitive protection performance: Equipped with advanced over-current and short-circuit protection mechanisms, the built-in high-precision current detection device can quickly and accurately sense the current changes in the circuit. Once the 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, effectively preventing the wires from overheating and the electrical equipment from being damaged due to overcurrent or short-circuit, providing timely and effective protection for the safety of household electricity consumption.
Compact and lightweight structure: the product is small in size and compact in structure, which is easy to be installed and arranged in the home power distribution box and saves space. Its lightweight characteristics also make the user more convenient in the process of installation and operation, without the need for complex tools and professional skills, reducing the threshold of use and operating difficulty, convenient for daily maintenance and inspection, but also conducive to the organisation and optimisation of the wiring in the distribution box, to enhance the overall aesthetics and practicality of the home electrical system.
3. Product use scene
Home lighting and socket circuits: widely used in lighting circuits and socket circuits in various rooms in the home. For lighting fixtures, such as chandeliers, wall lamps, ceiling lamps, etc., as well as sockets connecting all kinds of small electrical appliances, such as mobile phone chargers, desk lamps, fans, etc., the DZ47-60 2P circuit breaker can effectively prevent overcurrent problems caused by the failure of the lamps and lanterns or short-circuit of electrical appliances, etc., protect the normal operation of the lighting system, avoid the impact of the local circuit failures on the whole family's electricity consumption, and ensure that the basic electricity demand of daily life is safely guaranteed. Ensure that the basic electricity demand in daily life is safely guaranteed.
Kitchen and bathroom electrical appliances: In the kitchen and bathroom, where electrical appliances are concentrated, DZ47-60 2P circuit breaker plays an important role. Rice cookers, electric kettles, microwave ovens, ovens, dishwashers, etc. in the kitchen, and electric water heaters, bath tubs, washing machines and other electrical appliances in the bathroom, with large power and frequent use, are prone to overload. The circuit breaker can monitor the circuit current in real time, when the appliances are used at the same time or an appliance malfunctions resulting in excessive current, it will quickly cut off the power supply to protect the electrical equipment and personal safety, providing strong support for the safe use of electricity in the kitchen and bathroom, so that you can feel more at ease when using these appliances.
Home renovation and upgrading: during home renovation, it is a necessary part of the electrical system installation. Whether it is the electrical wiring of a new house or the electrical renovation and upgrading of an old house, the DZ47-60 2P circuit breaker can be reasonably configured according to the family's electricity needs to ensure that the new electrical lines are safe and reliable. 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
Installation and connection:
Install the DZ47-60 2P circuit breaker on the 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 fire wire input terminal of the circuit breaker (usually labelled ‘L’) and the zero wire to the zero wire input terminal (labelled ‘N’), pay attention to the correctness and firmness of the wiring to avoid the situation of connecting the wrong wires 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 to prevent heat generation 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 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 and odour. At the same time, check the wear degree of the contacts, and 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.
When operating the circuit breaker, the correct operation method should be followed to avoid damage to the circuit breaker caused by barbaric operation. Before closing, make sure that there is no short-circuit or ground fault in the load circuit; after opening the circuit, wait for a period of time before closing the circuit to avoid the danger caused by the residual charge present in the circuit.
