Main Features

This rugged design features show the highest reliability levels endorsed by extensive field use records. The V-Rupt parts are made of brass, silver-plated copper and tin-plated. The materials are chosen with particularly attention to galvanic corrosion.

  • The fuse holder is made with fiber-glass filament wound tubing resistant to UV rays and harsh weather. It is interchangeable and easily traceable due to the specific identification on the stick;

  • The fuse holder is equipped with expendable cap with rupture capacity of 8,275 kPa

  • (1,200lb/po2);

  • The cable terminals are sized for cables with diameter between 5 and 21 mm;

  • The insulator is especially made for the application following very strict specifications to ensure reliability and durability in a wide range of temperature and within harsh environment. Each insulator is identified for easy traceability;

  • Reverse current loop contacts at both line and hinge ends increase contact pressure during high surges preventing pitting and burning;

  • Positive lever operated latch prevents accidental opening;

  • High quality cast bronze construction. Stainless steel utilized in selected pins and springs;

  • Animal proofing;

  • Silver-plated, spring-loaded copper contacts

Design & Specifications

1. Stainless steel hook

  • For loadbreak tools like the LoadBuster

2. Expansion cap

  • Especially design to relief the pressure

  • Easily replaceable

High Strength U''V'' resistant fuse tube

  • Designed to handle the pressure


3. Plastic coated U-Bolt

  • Ensure a stable support

  • Ensure maximum durability at the support level compared to inserts

4. Stainless steel support

  • Dimensioned to facilitate the installation and ensure stability

  • Date code for traceability

5. Link Break Lever

  • All brass lever for easy and safe operation

  • Patented mechanism that ensure the breaking of the fuse

Linkbreak Attachment

The Linkbreak mecanism is designed so that it will break element of fuse links rated from 1/3 through 100 A with a minimum of effort. Fuseholder extinguishes load current as if fuse element had melted due to an overload condition.


  • Low initial cost compared to cutouts with integral loadbreak devices;

  • ​No complicated interrupter device to possibly fail;

  • Can be hookstick operated from ground with standard or extend stick. It is not necessary to climb the pole as it is for portable loadbreak tool in the event bucket truck is not available or location is such that it cannot be reached by bucket truck.

  • The circuit-breaker has a service life of 30 years in the extreme conditions of Quebec (temperature, humidity, salty air).

  •  The circuit-breaker's robustness and versatility enable it to be used in a wide range of applications, such as protection of transformers and capacitive networks. Transformers and capacitive networks

  • Robustness reduces false opening and minimizes maintenance and operator travel costs

  • A single model can be used across an entire electrical network, maximizing inventory management

Operational safety

  • Eyelet design facilitates fuse insertion on the base, especially when using long ground poles

  • Unique locking system ensures the fuse holder closes securely, ensuring the safety of line workers

  • Gripping hook design and position enables reliable use of LoadBuster for fuse opening

  • The expansion plug allows pressure to escape upwards in the event of a short-circuit, minimizing the risk of fire and protecting operators

  • The unique fuse attachment system prevents the fuse from elongating, thus reducing its breaking capacity. It also minimizes the need for operators to travel for maintenance

  • The "linkbreak" allows a lineman to manually break the fuse inside the tube. Although this destroys the fuse it allows the circuit-breaker to be opened, now de-energized, without the use of special tools, and will not create a dangerous arc. The design of the breaking mechanism provides a reliable break that no competitor can offer.
