Cylindrical fuse insert CH-10 10x38mm gG 6A 500VAC LF306G

Protection of Industrial Circuits and Low-Voltage Installations

The 10x38 mm fuse link is a key component in distribution systems where reliable protection against overloads and short circuits is a priority. This model, designed for mounting in cylindrical fuse holders, features a rated current of 6 A, making it suitable for control circuits, lighting, or smaller industrial loads. Thanks to its gG characteristic (full-range protection), the device responds to both prolonged overloads and sudden short circuits, ensuring safety for both conductors and connected equipment.

Durability and Electrical Parameters

The effectiveness of this solution is based on its high short-circuit breaking capacity. The fuse link has a short-circuit breaking capacity (Icn) of 120 kA at a rated voltage of 500 V AC. This means that even in the event of very strong short circuits in an industrial network, the element will operate immediately and safely disconnect the current, preventing damage to the installation or fires. The rated voltage of 500 V AC allows its use in typical three-phase and single-phase installations with elevated operating voltages.

It is worth noting the low power losses during continuous operation. At the rated current of 6 A, total power losses amount to only 0.85 W. This parameter is important for installers concerned with the energy efficiency of switchboards – it means minimal heating of the fuse link under normal operating conditions, which translates into the stability of the entire system and reduced thermal stress on adjacent components.

Applications and Construction Features

The fuse is made of ceramic, ensuring resistance to high temperatures generated during operation and mechanical durability. The absence of an operating indicator (in the version without a visual signal) is typical for this type of industrial component, where the fuse status is checked using a multimeter or by observing the operation of the load.

Main areas of application include:

• Protection of cables and conductors in industrial and building installations.
• Protection of low-power electric motors and control systems.
• Low-voltage switchboards where a high short-circuit breaking capacity (up to 120 kA) is required.
• Lighting systems requiring precise overload protection.

Key technical data include: rated current 6 A at 500 V AC and standard dimensions 10x38 mm. The gG characteristic provides full circuit protection, and the short-circuit breaking capacity reaches an impressive 120 kA. Low power losses of 0.85 W at rated current minimize component heating during continuous operation. This element is produced in bulk packaging (typically 10 pieces), facilitating logistics for larger renovation or construction projects. Thanks to compliance with IEC standards and high technical parameters, it constitutes a reliable solution for applications requiring an industrial standard.
