FAQ

Q： What are the precautions for installing indoor vacuum circuit breakers?: A：
Ensure the installation environment is dry, free of corrosive gases, and well-ventilated (meeting the IP4X protection class requirements). Check that the dimensions of the switchgear cabinet match those of the circuit breaker (e.g., withdrawable types need to be compatible with the switchgear rails), and fasten the connection terminals securely to prevent loosening and overheating. The insulation distance of the primary circuit must meet the standards (e.g., for 12kV products, the phase-to-phase and phase-to-ground clearances shall be ≥125mm).

Q： What are the differences between indoor vacuum circuit breakers and SF₆ circuit breakers?: A：
Arc-quenching medium: Vacuum circuit breakers use vacuum for arc quenching (environmentally friendly, no greenhouse gases), while SF₆ circuit breakers use SF₆ gas (requiring attention to gas leakage and environmental treatment). Volume and maintenance: Vacuum circuit breakers are smaller in size and have a longer maintenance cycle (the maintenance-free cycle can reach 10 years); SF₆ circuit breakers require regular detection of gas pressure.
