RMU Circuit Breaker
The SPFV-12D/T630 Vacuum Circuit Breaker is designed specifically for 12 kV SF6 gas-insulated Ring Main Units (RMUs). It integrates three-position functionality: circuit breaking (vacuum interrupter), isolation (disconnector), and earthing (earthing switch). Uses clamp-type structural design to enhance reliability and safety.
