The cylindrical fuse of type FR10GR69V10, manufactured by Lindner (manufacturer's number A1014576), is a fast-acting full-range fuse in the 10x38 mm format. It is designed to protect electronic components such as inverters, uninterruptible power supplies (UPS), frequency converters, and other discrete semiconductor components. This fuse is specifically designed for applications requiring rapid disconnection in case of overload or short circuit, to protect sensitive components from damage. The designation gR indicates a full-range fuse with fast action, which responds across the entire protection range from short circuit to overload. The fuse is designed for use in alternating current (AC) installations and meets the requirements for protective measures in industrial and technical installations.

Applications

The FR10GR69V10 fuse is used in installations operating electronic control and regulation systems, such as frequency converters or uninterruptible power supplies (UPS). These devices are often sensitive to current surges and overloads, making precise and rapid disconnection necessary. The fuse protects not only the electronic components but also the entire system from potential failures or damage. It is particularly suitable for industrial environments where high electrical loads and variable operating conditions prevail.

Functions and Features in Detail

The fuse is designed as a cylindrical insert, with a rated voltage of 690 V AC and a rated current of 10 A. The designation gR means that it is a full-range fuse with fast action, responding across the entire protection range from short circuit to overload. The fast action enables efficient disconnection in case of sudden current increases, which is especially important for protecting semiconductor components. The fuse is supplied without an indicator, meaning no visual signal is generated upon failure. Installation is carried out in suitable fuse holders designed for the 10x38 mm format.

Technical Explanation

The designation gR stands for a full-range fuse with fast action. Unlike slow-acting fuses (e.g. gG), the gR fuse responds to lower current overloads, making it particularly suitable for protecting electronic components. The rated voltage of 690 V AC allows use in industrial installations with high voltage. The rated current of 10 A defines the maximum current the fuse can carry continuously without tripping. The cylindrical shape with dimensions 10x38 mm is a standard format used in many fuse holders. The fuse is designed for use in AC installations, with the exact switching function determined by the materials used and the construction of the fuse element.

Compatibility and Accessories

The FR10GR69V10 fuse is designed for use in fuse holders supporting the 10x38 mm format. It is specifically designed for protecting inverters, UPS systems, and frequency converters. Use in other installations is possible, provided the electrical parameters (voltage, current, switching behavior) match the requirements of the installation. The fuse is supplied as a single unit, without additional components such as indicators or holders.

Installation and Mounting

Mounting is carried out in suitable fuse holders supporting the 10x38 mm format. The fuse is inserted into the holder and mechanically secured. Installation takes place in electrical circuits where protection of semiconductor components is required. The fuse must be installed in the circuit so that it directly protects the area before the load or component. Electrical connections must be secure and correctly executed to ensure reliable operation. The fuse is not designed for use in DC installations, as the specifications apply exclusively to alternating current (AC).

Operational Advantages

The fast action of the gR fuse enables efficient protection against sudden current increases, extending the service life of sensitive electronic components. The full-range protection ensures the fuse responds to both short circuits and overloads. The rated voltage of 690 V AC makes the fuse suitable for industrial applications where high electrical loads occur. The cylindrical shape is a standard format used in many fuse holders, facilitating interchangeability and compatibility. The fuse is supplied without an indicator, simplifying installation but providing no visual indication of failure.
