Cylindrical fuse insert CH-10 10x38mm gG 2A 500VAC LF302G

Protection of Low-Current Circuits in Industrial Installations

The 10x38 mm cylindrical fuse link is a key component for protecting control circuits, transformers, or small motors where precise protection against overloads and short circuits is required. This model, designed for 500 V AC, features a gG characteristic (full breaking capacity), meaning it effectively responds to both prolonged overloads and sudden short circuits. Thanks to its ceramic body, this element ensures high thermal and mechanical resistance, which is essential in industrial environments where installations may operate under harsh conditions.

Application and Key Protective Properties

The primary function of this fuse is to disconnect the power supply when current exceeds permissible values, thereby protecting more expensive equipment from damage. The rated current of 2 A makes it an ideal solution for low-power circuits. Note the low power losses at rated current, amounting to only 0.6 W. This ensures minimal heating of the fuse link during normal operation, resulting in stable electrical parameters and reduced load on the rest of the installation.

In the event of a short circuit, the fuse link demonstrates an impressive short-circuit breaking capacity of 120 kA. This value significantly exceeds typical requirements in many industrial and construction applications, ensuring that even under very high short-circuit currents, the fuse will operate safely without explosion or damage to adjacent components.

• Full protection (gG): Protects against all types of overloads and short circuits.
• High breaking capacity: 120 kA enables safe operation in networks with high short-circuit power.
• Low energy losses: Only 0.6 W power losses minimize component heating.
• Body material: Ceramic housing provides resistance to high temperatures and mechanical damage.
• Operating frequency: Designed for networks with a frequency of 50–60 Hz.

Installation and Compliance with Standards

Installation of this fuse link requires the use of appropriate CH-10 type fuse holders (or compatible ones), which are standard in industrial switchboards. The 10x38 mm dimensions are universal and allow for easy replacement in most existing installations without the need to upgrade control cabinets. The product meets rigorous safety standards, including RoHS and REACH directives, guaranteeing the absence of harmful substances in the production and disposal processes.

For installers, this means simple installation and reliable operation in accordance with the electrical design. For the end user, it ensures the safety of connected equipment and the longevity of the installation itself thanks to precise power disconnection during critical failure moments. Regular inspection of the technical condition of switchboards is essential, and fuse links should only be replaced with new elements having identical technical parameters: cylindrical ceramic shape for 10x38 mm dimensions, 2 A current, 500 V AC voltage, gG characteristic, 120 kA breaking capacity, and 0.6 W power losses.
