GA&DA RO17, fusible cilíndrico de 125 A, 22 x 58 mm

RO17 125A Fuse Link Overview

El GA&DA RO17 125A fuse link is a high-current cylindrical fuse designed for dependable overload and short-circuit protection in low-voltage electrical distribution systems.

Compared with smaller 10x38mm and 14x51mm cylindrical fuse links, the larger 22x58mm format supports higher-current applications while retaining the convenience of a replaceable cylindrical fuse system.

The RO17 series is suitable for electrical distribution equipment, industrial control panels, machinery and OEM assemblies where a compact but higher-capacity fuse solution is required.

For panel builders, electrical contractors and industrial buyers, the RO17 125A model provides a practical option when the circuit requires more current capacity than smaller cylindrical fuse formats can provide.

Características del producto

125A Rated Current

The RO17 model shown is rated at 125 A, making it suitable for higher-current circuits within industrial and commercial low-voltage distribution systems.

This current level is commonly required in feeder circuits, machinery power supplies and larger electrical panels.

22x58mm Cylindrical Fuse Size

The fuse uses a standard Formato cilíndrico de 22 × 58 mm.

Compared with smaller cylindrical fuse sizes, this larger body provides a suitable format for higher current ratings while maintaining simple installation and replacement.

gG Full-Range Protection

El producto está marcado gG, which indicates general-purpose full-range fuse protection.

This type of fuse is designed to protect circuits against both:

• overload currents
• short-circuit currents

Typical protection targets include cables, conductors, feeders and general low-voltage electrical equipment.

500V AC Rated Voltage

The fuse body clearly shows a 500V AC rating.

This allows the RO17 125A fuse to be used in a wide range of industrial and commercial low-voltage systems where the operating voltage is within the specified rating.

100kA Breaking Capacity

The product is marked with a 100kA breaking capacity.

A high breaking capacity is especially important in industrial installations where the prospective short-circuit current can be substantial. The fuse must be capable of safely interrupting the fault current without causing further damage to the electrical system.

Norma IEC 60269

The fuse is marked IEC 60269, indicating that the product is designed for applications covered by the international standard for low-voltage fuses.

Especificaciones técnicas

Typical Applications

El RO17 125A fuse link is suitable for electrical systems requiring higher-current cylindrical fuse protection.

Entre las aplicaciones típicas se incluyen:

• Industrial distribution boards
• Cuadros eléctricos
• Factory power distribution systems
• Armarios de control industrial
• Machinery power circuits
• Feeder protection
• OEM electrical equipment
• Commercial electrical distribution
• Automation systems
• Electrical panel assemblies

The 125A current rating makes the RO17 particularly suitable for circuits that require more protection capacity than typical 32A or 63A cylindrical fuse systems.

At the same time, the removable fuse format allows maintenance personnel to replace the fuse link without replacing the complete fuse holder or switching assembly.

Selection Considerations

When selecting the RO17 125A fuse link, engineers should evaluate the complete electrical system rather than choosing the fuse only by rated current.

Important selection factors include:

• Normal operating current
• Maximum expected load
• Tensión del sistema
• Cable and conductor rating
• Prospective short-circuit current
• Fuse operating class
• Portafusibles compatible
• Upstream and downstream protection
• Equipment starting or inrush current

The 125A rating should only be used where the conductor and connected equipment are designed for the corresponding current level.

For circuits containing motors, transformers or other equipment with temporary inrush currents, the fuse operating characteristics should be checked carefully to prevent unnecessary fuse operation during normal startup conditions.

Correct coordination also helps ensure that the fuse nearest to the fault operates first, reducing unnecessary shutdown of other parts of the electrical system.

Compatible Fuse Holder

The RO17 uses a Formato cilíndrico de 22 × 58 mm and should be installed in a compatible fuse holder.

Within the GA&DA product range, the corresponding option is:

RO17 Fuse Link + RT18-125 Fuse Holder

This combination provides a practical modular protection system for industrial distribution boards and electrical panels.

Using a correctly matched fuse holder helps ensure:

• correct physical fit
• reliable electrical contact
• convenient fuse replacement
• proper installation inside the panel
