Cylindrical fuse GL 125 A 22 x 58 HPC 015397

GL HPC cylindrical fuse link - professional installation protection

The LEGRAND GL HPC cylindrical fuse link with a current of 125 A and dimensions of 22×58 mm is a high-end electrical installation protection component, designed for professional installation in industrial switchboards and public utility buildings.

Construction and technical parameters

The ceramic fuse, manufactured using gG (full-range protection) technology, provides comprehensive protection for both cables and electrical devices against overloads and short circuits. The ceramic housing guarantees resistance to high temperatures and industrial conditions, making it an ideal solution for demanding applications.

The device operates at a rated voltage of 400 VAC and a current of 125 A, offering a high breaking capacity of 100 kA. This parameter allows for the safe interruption of even very large short-circuit currents, thereby protecting the entire installation from serious damage.

Power loss at the rated current is only 11,3 W, which translates to energy efficiency and minimization of thermal losses during normal operation.

Application and compatibility

The gG type fuse is characterized by a time-delay action (delayed tripping), allowing it to handle short-term current surges occurring during the startup of electric motors or other inductive loads perfectly. At the same time, it ensures rapid disconnection in the event of actual overloads or short circuits.

The universal AC/DC voltage nature enables use in various power systems - from standard building installations to specialized industrial applications. The operating frequency range of 42-62 Hz covers all standard grid frequencies.

The compact dimensions of 22×58 mm allow for space savings in switchboards, while simultaneously ensuring easy installation and removal by a professional installer.

Normative compliance and operating conditions

The product meets the requirements of the IEC 60269 standard, confirming its high quality and operational safety. The gG utilization category means that the fuse is intended for general use as a protective element for cables and electrical devices.

The fuse does not have a built-in indicator (indicator pin), which is typical for industrial applications where the device status is controlled by external electrical installation monitoring systems.

Thanks to its ceramic construction, the device maintains its parameters even in difficult environmental conditions, providing long-term and reliable protection of the electrical installation against the effects of overloads and short circuits.
