Mersen Fuse 22x58 40A 690V gG

Product Description

The Mersen Fuse 22x58 40A 690V gG is a general-purpose cylindrical fuse designed to protect lines, cables, and receivers in low-voltage panels. Its HRC technology with a ceramic body and quartz sand ensures rapid limitation of fault energy, reducing thermal and dynamic stress on connected conductors and equipment.

Main Features

• 22×58 mm dimension: universal format for cylindrical fuse holders.
• 40 A at 690 V AC: ideal range for distribution circuits and load supply.
• gG curve: complete protection against prolonged overloads and short circuits.
• Ceramic body and quartz sand filling: high breaking capacity and thermal dissipation.
• Silver-plated contacts: minimal voltage drop and improved long-term reliability.
• Compatible with 22×58 bases on DIN rail for 1P/2P/3P mounting.

Advantages or Benefits

• Greater operational safety thanks to its high breaking capacity.
• Effective protection that limits damage to cables and equipment, reducing downtime.
• Quick and economical replacement due to its standardized format.
• Excellent thermal and mechanical resistance for demanding industrial environments.
• Compatibility with selectivity and protection coordination schemes.

Purpose or Applications

Suitable for main panels, subpanels, protection of machine supplies, HVAC, lighting, pumps, and auxiliary services in commercial and industrial environments. Its gG class makes it versatile for most low-voltage alternating current circuits.
