- Vendor: Mersen
Specifications
Product Description
The Mersen Fuse 22x58 50A 690V gG is a high-performance cylindrical fuse designed to reliably protect cables, distribution lines, and equipment in low-voltage alternating current installations. Its HRC ceramic construction, with quartz sand filling and silver-plated contacts, ensures rapid arc extinction and a high breaking capacity in the event of severe short circuits. Thanks to its standard 22×58 mm format and gG utilization curve, it provides comprehensive protection (from prolonged overloads to direct faults), fitting perfectly in industrial electrical panels, motor control centers, and service subpanels.
Main Features
- 22×58 mm format: universal standard for cylindrical fuse holders and fuse switch disconnectors on DIN rail.
- Rated current 50 A and voltage 690 V AC: sized for power supplies and branches in industrial environments.
- gG class: general protection of lines and loads with fault energy limitation.
- HRC ceramic body with quartz sand: rapid arc extinction and high thermal resistance.
- Silver-plated terminals: low contact resistance, reduced heating, and long-term reliability.
- Easy integration in 22×58 bases 1P/2P/3P and simple replacement for maintenance.
Advantages or Benefits
- Superior electrical safety: limits thermal and dynamic stress on conductors and equipment during faults.
- Availability and standardization: widely used 22×58 format, ideal for spare parts and maintenance logistics.
- Reduced operating cost: quick replacement without special tools and high material durability.
- Versatility: suitable for general-purpose protection in distribution, machinery supply, HVAC, pumps, and industrial lighting.
- Compatibility: works with most fuse holders and disconnectors for 22×58 cartridges on the market.
Purpose or Applications
Recommended for main and sub low-voltage AC panels, protection of distribution lines, motor outputs with protection coordination, starting and switching, high-power lighting lines, pumps, industrial ventilation, and auxiliary services in process plants, logistics centers, and commercial buildings.
