Ferrule fuse-links 14x51 gG 500 to
690VAC

LOW VOLTAGE IEC FUSES

IEC CYLINDRICAL FUSE-LINKS

FEATURES & BENEFITS

• Reduced size

• Full range protection

• Striker version available for remote
indication of fuse operation

• Safest and most reliable protection
system

Mersen aM and gG fuse-links cover a wide range of physical sizes and
ampere ratings for 400, 500, and 690VAC for protection in electrical
distribution circuits and various industrial applications. Most ratings
are available in size 8x31 and size 10x38 with an optional indicator,
and in size 14x51 and 22x58 with an optional striker to activate
an auxiliary contact. Size 10x38 is also available with striker. All
cylindrical fuse-links have ceramic bodies and silver-plated contacts.

Cylindrical fuse-links “gG” are used for the protection of cables,
motors and LV-networks. They limit and cut o unacceptable
overcurrents and short-circuit currents up to their nominal breaking
capacity. Cylindrical fuse-links “gG” also protect electrical equipment
and installations against the dynamic eect of high short-currents.

Our technology and process was designed to ensure highly reliable
technical performance.
