Introducing RN Series Indoor Medium and High Voltage Fuses

1. Introduction to RN1 high-voltage fuse

RN1 high-voltage fuse is a high-voltage fuse used for overload and short-circuit protection of power systems and electrical equipment. It can quickly melt when the current exceeds the specified value, thereby cutting off the circuit and protecting electrical equipment from damage. RN1 high-voltage fuse has the advantages of simple structure, easy use, safety and reliability, and is widely used in power systems.

Wenzhou Shuguang Fuse Co., Ltd. (SR brand) indoor high voltage current limiting fuses strive to provide protection for your power system. As a fuse manufacturer with more than 30 years of manufacturing experience, we can provide wholesale prices, reliable quality, and fast delivery.

2. Detailed explanation of usage steps

1. Preparation before installation

(1) Select a suitable RN1 high-voltage fuse. According to the rated voltage, rated current and protection requirements of the electrical equipment, select the appropriate RN1 high-voltage fuse model and specification.

(2) Check the appearance of the fuse. Make sure that the appearance of the fuse is intact, without cracks, deformation, etc., and the lead connection is firm and not loose.

(3) Prepare installation tools. Prepare the required installation tools, such as screwdrivers, wrenches, etc., and make sure the tools are clean and free of oil.

2. Installation process

(1) Disconnect the power supply. Before installing the RN1 high-voltage fuse, the power supply must be disconnected to ensure the safety of the installation process.

(2) Fix the fuse base. Fix the fuse base in a suitable position and ensure that the base is vertical to the ground without shaking.

(3) Connect the leads. Connect the leads of the fuse to the corresponding wires in the circuit to ensure that the connection is firm, reliable and not loose. Note that the color of the leads should correspond to the color of the wires in the circuit to avoid connecting the wrong wires.

(4) Install the fuse tube. Install the selected fuse tube into the fuse to ensure that the fuse tube and the fuse base are in good contact and there is no jamming. Note that the rated current of the fuse tube should match the rated current of the electrical equipment.

(5) Close the fuse cover. Close the fuse cover and fix it firmly with screws to ensure that the fuse will not open or fall off by itself during normal operation.

3. Maintenance after use

(1) Check the fuse regularly. Regularly check the appearance and connection wires of the RN1 high-voltage fuse to see if they are in good condition. If any abnormality is found, the fuse should be promptly handled or replaced. It is recommended to conduct a comprehensive inspection every quarter.

(2) Pay attention to the ambient temperature. The working environment of the RN1 high-voltage fuse should avoid excessively high or low temperatures to avoid affecting its performance and service life. Generally speaking, the working environment temperature should be between -40 and +40.

(3) Avoid humid environments. A humid environment may cause the internal components of the RN1 high-voltage fuse to become damp and corroded, thereby affecting its normal operation. Therefore, try to avoid installing the fuse in a humid environment.
