Lindner C214063 Mersen DIIIGG50V35 fuse insert gG DIII AC500V 35A black content_copy

The D-fuse system from Lindner, type DIIIGG50V35, is a screw-type fuse system of the first generation designed for use in low-voltage installations. It provides protection for electrical circuits and installations against excessive overcurrents and short-circuit currents up to the rated switching current. The fuse inserts are designed to be accessible and replaceable even by non-specialists, making them widely used in many industrial and commercial installations. The system includes various sizes, including NDZ, DII, DIII, DIV, and DV, with type DIII specified here. The operating class gG ensures that the fuse can also absorb the electrodynamic effects of high short-circuit currents on electrical equipment and installations. The standard DIN VDE 0636-30 forms the basis for the technical requirements and approval of these fuse inserts.

Applications

The fuse insert DIIIGG50V35 is intended for use in low-voltage installations, particularly in systems where simple and safe replacement of fuse inserts is required. It is commonly used in industrial, commercial, and partially also in municipal electrical installations, where the protective function for circuits and electrical equipment is of central importance. Use in installations maintained by non-specialists requires a robust and reliable fuse that does not fail even with frequent replacement.

Functions and Equipment in Detail

The fuse safely interrupts excessive overcurrents and short-circuit currents, with the rated switching current representing the maximum current value up to which the fuse can still interrupt safely. The operating class gG is intended for the protection of electrical installations and equipment, particularly against the mechanical and thermal stresses caused by high short-circuit currents. The fuse is designed for use in alternating current installations, with a rated voltage of AC 500 V specified. The rated current is 35 A, indicating the maximum current the fuse can carry continuously without tripping.

Technology Explained Simply

The fuse operates on the principle of thermal and electromagnetic interruption. In the event of an overcurrent or short circuit, the fuse element heats up and melts, thereby interrupting the circuit. The operating class gG means that the fuse is suitable for general protection of circuits and installations and can also absorb electrodynamic forces during high short-circuit currents. The protection type DIII refers to the mechanical design and dimensions of the fuse insert, intended for mounting in corresponding fuse holders. The rated voltage AC 500 V defines the maximum voltage operation at which the fuse functions reliably.

Compatibility and Accessories

The fuse insert is designed for use in D-fuse holders of size DIII. It is compatible with fuse holders manufactured according to DIN VDE 0636-30 and meeting the corresponding dimensions and mounting specifications. Use in other fuse sizes is not intended and may lead to malfunctions or hazards.

Mounting and Installation

Mounting is carried out in a suitable fuse holder of size DIII, ensuring that the screw connection is securely and tightly tightened to guarantee a reliable electrical contact. Installation is typically performed by qualified electricians, adhering to the regulations of DIN VDE 0636-30 and relevant safety regulations. The fuse is intended for use in enclosed switchgear, with accessibility for replacement taken into account.

Advantages in Operation

The fuse provides reliable protection for electrical installations and circuits. The simple replaceability allows for quick restoration of power supply after a failure. The operating class gG ensures a high level of protection, especially under high short-circuit currents. Compliance with the standard DIN VDE 0636-30 ensures conformity with applicable safety standards. The rated voltage AC 500 V and rated current 35 A make the fuse suitable for a wide range of applications in low-voltage technology.
