2. The main characteristics of the product
High current carrying capacity: the rated current range is from 80A to 125A, which can meet the needs of high power electrical equipment, suitable for the protection of large motors, welding machines, heating equipment in industrial production, as well as central air-conditioning, lifts and other high-power loads in commercial premises, to ensure that these equipments can be supplied with stable power supply in normal operation, and also to cut off the circuit quickly in the case of overcurrent or short-circuit faults, to prevent damage to the equipment and electrical accidents. and electrical accidents, to ensure the continuity of production and operation.
Multiple polarity adaptability: 1P, 2P, 3P and 4P configurations are available, which can be flexibly selected according to different power scenarios and electrical system requirements. 1P and 2P are suitable for single-phase circuits, such as high-power electrical appliances in the home or some of the single-phase equipments in small commercial establishments; 3P and 4P are used in three-phase circuits, which meet the protection needs of three-phase power equipments and three-phase four-wire power supply systems in the industrial and commercial fields, and realise the protection of different types of circuits. 3P and 4P are used for three-phase circuits to meet the protection needs of three-phase power equipment and three-phase four-wire power supply systems in the industrial and commercial sectors, to achieve precise protection of different types of circuits and to optimise the safety and reliability of electrical systems.
3. Product use scene
Industrial production field: In the production workshop of factories, it is used for the electric power protection of all kinds of large-scale production equipment, such as press machine tools, injection moulding machines, cranes, industrial fans, etc. These equipments usually have large power and high current during operation. These equipments usually have larger power and higher current during operation, the high current carrying capacity and reliable protection performance of DZ158-125 circuit breaker can ensure stable operation of the equipments, prevent interruption of production due to electrical faults, improve production efficiency, reduce the maintenance cost of the equipments and the production loss, and provide a strong guarantee for the smooth progress of industrial production.
Commercial facility application: It is suitable for the electrical system of commercial places, such as shopping centres, hotels, office buildings, supermarkets, etc. in the central air-conditioning system, lifts, ventilation equipment, lighting systems, and all kinds of commercial power equipment in the distribution box. Its multiple pole configurations can meet the power supply needs of different equipment, and at the same time, in the face of the complex power environment and high load operation of commercial premises, it can effectively protect the electrical system from overload and short circuit, ensure the normal development of commercial activities, and avoid the economic losses and customer satisfaction caused by power outages.
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. You can use professional electrical test instruments, such as multimeters, clamp-on ammeters, etc., 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. Test the overload protection function by gradually increasing the load current until it exceeds the rated current of the circuit breaker, and observe whether the circuit breaker can act within the specified time; at the same time, it can also simulate a short-circuit situation to check whether the short-circuit protection function is normal. If problems are found, the wiring, current setting and internal structure of the circuit breaker should be checked in time for corresponding adjustment and repair.
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 and so on. 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.
