Monoruptr® Vacuum Interrupters

115 kV Center Vee with SEECO one bottle interrupter



Type: SM, CM and VM

Number of Vacuum Bottles: 1

A single bottle vacuum interruption device for use with both SEECO and non-SEECO group operated switches, including side-break, center-break and vertical-break configurations. 

Provides interruption capabilities in switching applications where the recovery voltage does not exceed 30 kV peak and a maximum interrupting current of 3000 amps.  Common switching applications for single bottle interrupters include:

  • Load dropping - 70% pf of load interruption up to 25 kV on ungrounded systems and 34.5 kV on solidly grounded systems

  • Line dropping - to 25 kV or 72.5 kV with voltage limiter

  • Loop splitting (parallel break) - to 230 kV if recovery voltage does not exceed 30 kV peak

Monoruptr® vacuum interrupters are not designed or rated for fault duty.  Please contact the factory for confirmation of the appropriate interrupter configuration for your specific requirements.
