Cylindrical fuse insert CH-22 22x58mm gG 100A 500VAC LF590G

Protection of Industrial Circuits and Low-Voltage Switchgear

The cylindrical fuse link with dimensions 22x58 mm is a key component in electrical protection systems, designed for installation in industrial switchboards and installations requiring high reliability. The device, designated LF590G, features a rated current of 100 A and is suitable for operation in alternating current (AC) networks with a voltage up to 500 V. Thanks to the application of the gG (general-purpose) characteristic, this element effectively protects conductors and equipment against overloads and short circuits, responding both to prolonged current exceedances and sudden current spikes.

Ceramic Construction and Operational Parameters

The unit is constructed as a ceramic cartridge, ensuring resistance to the high temperatures generated during operation. Inside, a filler material allows for safe arc extinction during high-power short circuits. A key parameter for the installer is the power dissipation capability: at the rated current of 100 A, the power loss is only 9 W, minimizing heating of the fuse housing and the surrounding environment under continuous operation conditions.

It is worth noting the high breaking capacity: in accordance with the IEC 60898-1 standard, this fuse link has the ability to safely interrupt a short-circuit current of up to 120 kA. This means that even in the event of very strong short circuits in the installation, the element will operate without the risk of explosion or damage to neighboring switchboard components.

Applications and Benefits for Installations

The product is ideally suited for circuits powering electric motors, transformers, and other inductive devices that generate short-term current spikes during startup. Thanks to the specific tripping characteristic (gG), the fuse link will not operate incorrectly in response to such impulses, but only in the event of a genuine threat to the installation.

• Mounting versatility: Standard dimensions of 22x58 mm allow for easy replacement in most fuse holders used in Europe.
• Safety: The ceramic housing isolates the interior of the fuse from the environment even after it has blown.
• Low energy losses: The low power loss value (9 W) translates to lower energy consumption in the system and reduced operating costs.
• Compliance with standards: The product meets the rigorous requirements of European standards for low-voltage fuses.

Summarizing the key technical data: the fuse link handles a rated current of 100 A at a voltage of 500 V AC, and its dimensions are 22 x 58 mm. Under full load, it loses only 9 W of power, which is an optimal value for continuous operation. The ability to dissipate short-circuit currents reaches up to 120 kA, making it highly resistant to network failures. The entire unit is made of ceramic and features a gG characteristic intended for general-purpose applications.

Thanks to the combination of a robust ceramic construction with precise electrical parameters, the LF590G fuse link forms a reliable foundation for the safety of modern electrical installations, both in industrial and commercial facilities.
