Cylindrical fuse insert C 8, 5x32mm gG 10A 400VAC L8532C10

Protection of power circuits in industrial and domestic installations

The cylindrical fuse cartridge with dimensions 8.5x32 mm is a key element for the safety of electrical installations, designed for operation in AC circuits. The device, designated with the code L8532C10, serves to protect against overloads and short circuits, which is particularly important in 400 V power supply systems. Thanks to the gG (general purpose) tripping characteristic, the cartridge effectively protects cables and equipment from long-term overloads and ensures rapid power disconnection in the event of a short circuit.

Construction and operational parameters

The unit is made of ceramic, which guarantees resistance to high temperatures generated during fuse operation. The rated current is 10 A, allowing its use in circuits with moderate loads. It is worth noting that the total power loss at rated current does not exceed 1.10 W, which translates to less heating of the element during normal operation and higher energy efficiency of the system.

The rated short-circuit breaking capacity (Icn) according to standard IEC 60898-1 is 10 kA. This means that the fuse is capable of safely interrupting a short-circuit current of up to 10 000 amperes without the risk of explosion or damage to adjacent installation elements. This is a standard value for this type of cartridge, sufficient for most applications in residential buildings and small production plants.

Application and installation

These cartridges are intended for installation in fuse holders dedicated to the 8x32 mm size (often referred to as size C). Their universal gG characteristic makes them suitable for protecting power cables – preventing overheating during overloads – as well as electric motors, which require tolerance for short-term inrush current spikes. They are also standardly used as protection for final circuits for lighting and socket outlets.

Key technical data can be quickly verified without the need to consult tables: the product handles a rated voltage of 400 V AC at a current of 10 A. Dimensions 8.5 x 32 mm define its compatibility with appropriate holders. The tripping characteristic is gG, and the short-circuit breaking capacity reaches 10 kA. At full load, power losses amount to only 1.10 W, and the housing is made of durable ceramic.

The package usually contains a set of 10 cartridges, facilitating their replacement during maintenance of larger installations or as a spare for service. Thanks to compliance with IEC standards and the EU Declaration of Conformity, the product meets the rigorous safety requirements set for protective elements in Europe. Installation requires only matching the appropriate fuse holder – the cartridge itself does not have additional control mechanisms or tripping indicators (in the standard version), which simplifies its construction and increases mechanical reliability.
