Functions and applications- Function: distribution of a high-power supply to several feeders while ensuring continuity of service and reliability.
- Applications: industrial and commercial electrical installations, distribution panels and cabinets requiring controlled power distribution.
- Usage recommendations:
- Select the appropriate configuration based on the number of feeders and required cross-sections.
- Respect the rated current to ensure safety and longevity.
- Use conductors matching the recommended cross-sections for each output.
- Apply correct tightening torques to ensure reliable connections.
- Implement periodic inspection of connections to prevent overheating risks.
