ARCRITZ Opening Device Under Load (DAC)

The ARCRITZ load opening device is designed for energized networks up to 25kV. As well as offering safe maneuvering with fuses and disconnectors, it guarantees reliability on single-phase or three-phase circuits. It uses an insulated operating rod, providing total operator safety even in energized environments.

What’s more, ARCRITZ maintains its performance even in environments with high levels of pollution and humidity.

Compatible with single-phase and three-phase networks, ARCRITZ provides safety and efficiency during preventive and corrective maintenance. It has also been designed to operate in resistive, capacitive and inductive circuits. In this way, the device offers robustness and reliability in the field.

Typical applications

• Overhead power distribution networks
• Operations with fuses and disconnectors
• Corrective and preventive maintenance

Benefits and differentials

• Reinforced insulation: fiberglass body with high electrical and mechanical performance.
• Robust components: durable metal parts with a long service life.
• Efficient arc extinguishing: the internal chamber dissipates the arc quickly. This minimizes operational risks.
• Control of service life: the built-in cycle counter makes it possible to monitor the wear and tear of the equipment. This allows the operator to act with precision.
• Operational safety: operation with an insulated operating rod, protecting the electrician throughout the process.

In this way, electricians gain efficiency and safety in the field, even during critical operations.
