Technical Parameters

Operation and Maintenance

• High Reliability and Low Maintenance: The design, particularly the vacuum interrupter and solid-sealed insulation, makes the breaker highly reliable and virtually maintenance-free throughout its service life.

• Operating Principle: When the breaker closes, the closing spring releases energy to close the contacts and, in the process, charges the opening spring. To open the circuit, the opening spring is released, separating the contacts.
