Monoruptr® Vacuum Interrupters

Type: SM
Voltage: 46 – 115 KV
Maximum Interrupting Current: 3000 Ampere

Number of Vacuum Bottles: 2 – 4

Description
A multi bottle vacuum interruption device for use with SEECO one-way, phase-over-phase switches. Interrupter is horizontally mounted to minimize phase spacing. Provides full load or reduced voltage interruption capabilities.

Application
Common applications for multi bottle interrupters include:

  • Load dropping
  • Line dropping
  • Loop splitting (parallel break)

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

  • Minimizes phase spacing and pole height
  • Provides arc-less switching
  • Supports load management, remote switching and automatic sectionalizing schemes
  • Full load interrupters provide convenience, flexibility and clarity in switching; reduces confusion about switching “rules” under various operating conditions
  • 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
  • Environmentally friendly – dielectric medium is a silicon oil; no special handling or disposal procedures required
  • Safety – no SF6 that can produce hazardous byproducts, when exposed to an arc
  • Quick, simple field installation
