4. Product use instructions
Preparation before installation:
Carefully check the appearance of the circuit breaker to see if there are defects such as breakage, deformation, contact oxidation, shell cracks, etc. If there are any problems, the supplier should be contacted for replacement in time to ensure that the quality of the NXBLE circuit breaker to be used is intact and undamaged.
Determine the required circuit breaker current specification according to the actual application scenario and the design requirements of the electrical system, and prepare suitable installation tools, such as screwdrivers, wrenches, sharp-nosed pliers, wire strippers, etc., to ensure the precision and applicability of the tools, so as to avoid damaging the circuit breakers during the installation process.
Installation and Connection:
Install the NXBLE circuit breaker on the rail of the distribution box or distribution cabinet, ensure that the installation is firm and free from looseness. Correctly connect the power and load wires according to the wiring plan of the electrical system. In general, the power supply line is connected to the input terminal of the circuit breaker (usually labelled ‘LINE’ or ‘IN’), and the load line is connected to the output terminal (usually labelled ‘LOAD’ or ‘OUT"), pay attention to the correctness and firmness of the wiring to avoid wrong wiring 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, fire or failure 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 situations to test whether the circuit breaker's protection function is sensitive and reliable.
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.
