Two-Way 69 kV Monoruptr(R), Type 2M



Type: 1M, 2M and 3M
Voltage: 15 - 230 KV
Maximum Interrupting Current: 3000 Ampere

Number of Vacuum Bottles: 1 - 8

A vacuum interruption device for use with SEECO one-way, two-way and three-way phase-over-phase switches.  Provides full load or reduced voltage interruption capabilities.

Common applications for single and 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

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

Cost effective - one interrupter unit is shared by all sides of two and three-way switches

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
