Cylindrical fuse-links

Product catalog summary

Overview: This document provides detailed specifications and technical information about cylindrical fuses, specifically gG and aM classes, used for general protection and short circuit protection in various electrical applications.

Specifications: The document lists various cylindrical fuses with their respective reference numbers, voltage ratings, breaking capacities, and packaging details. The fuses are categorized by size and type, including gG and aM classes, which are designed for different protection needs.

gG Cylindrical Fuses: These fuses are intended for general protection against overloads and short circuits, suitable for cables, power lines, and equipment. They are made of ceramic tubes with high resistance to internal pressure and thermal shock, ensuring high breaking capacity in compact spaces. The fuses feature silver-plated copper contact caps and are available with fusing indicators or strikers.

aM Cylindrical Fuses: Designed for short circuit protection in motors and transformers, these fuses offer excellent current limiting capabilities and low I2t values. They must be used with an overload protection device. Similar to gG fuses, they are made of ceramic tubes and have silver-plated melting elements and contact caps.

Standards and Approvals: The fuses comply with IEC 60269-1, IEC 60269-2, EN 60269-1, and EN 60269-2 standards. They are also in line with Directive 2002/95/EC.

Technical Characteristics: The document includes detailed technical data such as t-I characteristics, cut-off characteristics, power dissipation, and I2t characteristics for both gG and aM fuses. It also provides information on DC applications, noting that DC performance differs from AC and requires specific considerations.

Dimensions and Compatibility: The document outlines the dimensions of various fuse sizes and their compatibility with different fuse holders, including panel mounting, screw fixing, and modular types.

Contact Information: The document concludes with contact details for the head office and factory in Barcelona, Spain, including phone numbers and email addresses for export and national sales.

CYLINDRICAL FUSES gG CYLINDRICAL FUSES DC APLICATIONS TECHNICAL Fuses are generally suitable for both AC and DC applications. The DC performance of fuse-links is different and AC ratings cannot be used for DC applications. There is no simple rule that safely converts an AC voltage rating of a fuse-link to DC voltage rating. For this reason it is necessary to take into account a lot of aspects in order to determine the DC applications. In the DF ELECTRIC gG cylindrical fuses it is necessary to take into account the following considerations: • The power dissipations are the same in AC (RMS value)...
