Solutions

 

1. Stationary (Fixed) Executive Model

The stationary vacuum circuit breakers from METTZ are designed for fixed installations. These robust and secure devices provide a stable integration within the electrical framework. Suitable for scenarios where mobility is not required, they offer consistency and reliability. The fixed model is ideal for permanent structures, ensuring safety and uninterrupted functionality. Here’s what sets it apart:

Stable Performance: Once installed, these devices offer continuous, efficient performance without the need for adjustments or repositioning.

Cost-Effective: Often, the fixed version can be more budget-friendly as it does not include the mechanisms necessary for mobility.

Space Efficient: The stationary configuration typically takes up less space, fitting neatly into the allocated area.

Application Areas: Ideal for power plants, substations, and industrial applications where the configuration remains constant.

 

2.Roll-Out Trolley Model

In contrast, the roll-out trolley vacuum circuit breakers offer flexibility and mobility. This design allows the breakers to be moved and adjusted, providing versatility for different applications or maintenance needs. Here’s what distinguishes this model:

Adaptability: Easily repositioned and adjusted, this version adapts to various configurations and requirements.

Ease of Maintenance: The roll-out trolley allows easy access for maintenance, inspection, and upgrades.

Versatile Applications: From temporary setups to environments that require frequent reconfiguration, this model offers solutions.

Innovation in Design: The roll-out trolley design embodies innovation, offering an intelligent solution for complex requirements.

Conclusion: Tailored Solutions for Diverse Needs

METTZ Group understands that different clients have unique demands, and it’s not always a ‘one-size-fits-all’ scenario. Whether the task requires a solid, stationary setup or a flexible, movable system, METTZ offers solutions that are crafted to meet these distinct needs.

By providing both stationary and roll-out trolley vacuum circuit breakers, METTZ not only offers choices but delivers quality, innovation, and adaptability. This customer-centric approach ensures that you can select the configuration that best aligns with your goals and challenges.
