Список контрольных критериев отбора
Specify the Vacuum Circuit Breaker for the Network
- Define the electrical duty. State rated voltage, continuous current, frequency, short-circuit breaking current, making current and insulation levels.
- Choose the construction. Confirm outdoor or indoor installation, common-box or pole-mounted arrangement, vacuum interrupter and insulation medium.
- Match the operating mechanism. Specify manual, motor or stored-energy operation, trip/close coil voltage, auxiliary contacts and control interface.
- Check the site environment. Provide altitude, ambient temperature, humidity, pollution, wind, seismic and enclosure requirements.
- List documents and quantity. Include drawings, wiring diagram, routine-test evidence, packing, destination market and delivery requirements in the RFQ.
Configuration and supply boundary
Review the Column Configuration
The supplier listing identifies a vacuum-circuit-breaker model family. State the exact model code and switching arrangement so the quotation does not mix ratings or accessories from another series.
Mechanism and controls
Specify stored-energy mechanism, motor and coil voltages, auxiliary contacts, interlocks and local/remote control.
Structure and environment
Confirm pole arrangement, insulation housing, enclosure, altitude, temperature, pollution and installation interface.
Commercial boundary
Quantity, packing, delivery schedule, private label and project documents remain subject to technical review and quotation.

Часто задаваемые вопросы
Column Vacuum Circuit Breaker FAQ
Which values should be matched first?
Start with rated voltage, continuous current, short-circuit breaking capacity, insulation levels, operating sequence and installation environment.
Are ratings interchangeable between vacuum-breaker series?
No. Confirm the exact model code and source table. Do not transfer ratings, dimensions or accessories from a similar-looking series.
Can the controls and fittings be customized?
FUERTE publishes adaptation of mounting hardware and project specifications as an OEM/ODM scope. Availability depends on technical review.
Что должно быть включено в запрос на предоставление предложения?
