SF6 Gas Circuit Breaker

General Information

EFG brand SF6 Gas Circuit Breakers are designed in a sealed pressure structure that does not require SF6 gas supplementation for 30 years, in accordance with TS EN 62271-100 standard.

Working Mechanism

The breaker operating mechanism works with the energy accumulated in a spring arrangement, which provides an “On-Off-On” operation cycle without the need for a separate operation, suitable for the remote control system, can be set up by hand or with a motor. The closing spring is installed by the electric motor, and the opening spring is installed automatically when the breaker is closed. There is a locking system that prevents the breaker from operating if the closing spring is not fully installed.

Opening and Closing Patterns

Opening and closing operations can be done remotely with the help of opening and closing coils and also mechanically with the button on the front of the breaker operating mechanism in case of emergency. There is a mechanical indicator showing the open and closed states of the breaker on the operating mechanism and a mechanical counter that records the number of openings.
