Monoruptr® Vacuum Interrupters

Type: SM, CM and VM

Number of Vacuum Bottles: 1

Description
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.

Application
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.

Features & Benefits

  • Provides arc-less switching
  • Supports load management, remote switching and automatic sectionalizing schemes
  • Interrupter units are out of the main current path when not in operation and are not subject to fault currents
  • Proven vacuum bottle technology with an established history of successful field service
  • Safety – no SF6 that can produce hazardous byproducts, when exposed to an arc
  • Quick, simple field installation
