Overview

The ABB MVS3-21-27-22-MO120A is a subsurface molded vacuum switch designed for medium-voltage applications requiring reliable three-phase operation at 27kV. This switch features 200 Amp bushing well terminations, enabling direct connection to high-current circuits without additional adapters. The integrated 120 VAC motor provides remote or automated operation, eliminating the need for manual switching in underground or enclosed installations. Built for underground distribution systems, this vacuum switch meets the demands of utility substations, industrial power networks, and commercial facilities where space constraints and environmental protection are critical. The molded vacuum interrupter ensures consistent performance in harsh conditions, with no external arc or contamination risks. The 27kV rating aligns with ANSI C37.71 standards for medium-voltage switchgear, ensuring compatibility with standard utility and industrial systems.
  • 27kV three-phase medium-voltage rating for ANSI C37.71 compliance
