Cylindrical fuse insert CH-10 10x38mm gG 10A 500VAC LF310G

10 A Circuit Protection in Industrial Standard

The 10x38 mm cylindrical fuse link is a key component for the stability of electrical installations requiring protection against overloads and short circuits. This model, designed for mounting in CH-10 holders, offers full versatility thanks to its gG (general application) characteristic. This means it effectively protects both cables and conductors, as well as end-use equipment, from the effects of prolonged overloads and sudden short circuits. With a rated voltage of 500 V AC, this component is suitable not only for typical domestic installations but primarily for more demanding industrial environments where the network may be exposed to higher operating voltages.

High Breaking Capacity and Energy Efficiency

One of the most important features of this fuse is its ability to safely interrupt the circuit even under very high short-circuit currents. According to technical data, the breaking capacity (Icn) reaches 120 kA. This is a critical parameter for installers – it means that in the event of a serious short circuit, the fuse link will not fail explosively but will safely cut off the current, protecting the rest of the system from mechanical damage or fire. It is worth noting that despite such high performance, this component is designed to minimize energy losses. At the rated current of 10 A, the power loss is only 1 W. Such a low value of fuse heating translates into reduced thermal stress on the holder and lower operating costs in systems operating under continuous load.

Ceramic Construction and No Indication of Operation

The construction of the fuse link is based on a ceramic body, ensuring resistance to the high temperatures generated during operation. This is a standard material for cylindrical fuses of this class, guaranteeing durability and safe operation. However, it should be noted that this model has a specific feature: it does not have an operation indicator (so-called "piston"). This means that after the fuse link blows, there is no external visual signal (e.g., protruding plunger or color change), requiring the installer to use a multimeter or visually inspect the holder to confirm the fuse status.

Thanks to its compact dimensions of 10x38 mm and the standard gG characteristic, this fuse link fits perfectly into distribution boards and constructional switchgear. In practice, this means handling a rated current of 10 A at a voltage up to 500 V AC, while maintaining low power losses at the level of 1 W. The high short-circuit capacity of 120 kA ensures reliable operation even under the most demanding network conditions. This is a time-tested solution that requires no complex configuration – it simply fits into dedicated sockets and performs its protective function throughout the entire lifecycle of the installation.
