Overview

The ABB NMVI3-21-27-66-20-PS is a three-phase, 27kV rated network molded vacuum interrupter designed for medium-voltage switchgear applications. This unit delivers a continuous current rating of 600A, making it suitable for distribution systems requiring reliable fault interruption and load switching. The NMVI3 series integrates a 120VAC motor for automated operation and includes a parking stand for safe storage of the vacuum bottle when not in use. Key specifications include a bushing-type connection, ensuring compatibility with standard switchgear assemblies. The interrupter is rated for 27kV phase-to-phase voltage, providing insulation and arc interruption capabilities in compliance with ANSI/IEEE and IEC standards. The 600A current rating supports medium-voltage distribution systems in industrial plants, substations, and commercial facilities where frequent switching or fault interruption is required. The NMVI3-21-27-66-20-PS includes a network control module for remote monitoring and operation, enhancing system integration and automation. The 120VAC motor drive enables precise control of the vacuum interrupter mechanism, ensuring consistent performance under varying load conditions. The integrated parking stand minimizes mechanical stress on the vacuum bottle during maintenance or storage, extending operational lifespan. This vacuum interrupter is part of ABB’s NMVI3 series, a proven solution for medium-voltage applications requiring high reliability and low maintenance. Typical use cases include primary and secondary distribution switchgear, motor control centers, and industrial power systems where arc interruption and load management are critical. The unit’s compact design and standardized connections simplify installation and replacement in existing systems. For applications demanding high interrupting capacity and long-term durability, the NMVI3-21-27-66-20-PS provides a robust, field-proven solution. ABB’s engineering ensures compliance with stringent electrical and safety standards, making it a trusted choice for utilities, industrial operators, and infrastructure projects.
