low cost sf6 circuit breaker Insulated Equipment

The sealed tank, rated IP65, contains the circuit breaker and three position disconnect switch. The equipment is insulated using SF6 gas. Sealed tanks isolate the primary live parts from contaminants and reduce maintenance requirements. Tanks are machine welded at the factory and sealed for life. Tanks do not require any on-site gas filling.
